10 Best Touchscreen Laptops in The World

2011-10-22T11:43:00.000-07:00

What's the best touchscreen laptop?

The touchscreen has truly arrived, and you only need to take one look the success of the iPad and the army of Android tablets bursting onto the market, such as the Samsung Galaxy Tab, to see that.

However, if you'd rather have a keyboard for writing emails, and then a touchscreen for a natural way to surf the web and browse your photos, then a laptop could be a much more sensible purchase.

There are plenty of great touchscreen laptops on the market, and there's a model to suit every need. From swivel screens on tiny netbooks, to full size laptops with touch capability, we take you through the best touchscreen laptop options.

1. Samsung NB30 – £268

touchscreen laptops

Samsung's netbook range has always impressed us, and the NB30, boasting tactile touchscreen technology is no exception. It's easy to carry, and the touchscreen gives it a near tablet feel, although the screen doesn't twist around to give the true form factor.

The 10.1-inch screen has a 1,024 x 600-pixel resolution, and it's sharp and bright, and there's no shiny Super-TFT screen coating causing irritating reflections in bright light. What's more, this is the cheapest touchscreen PC you're likely to find.

Buy the Samsung NB30 touchscreen netbook

2. Vye V-91015 Touch Screen Netbook – £379

touchscreen laptops

There are a number of twistable tablet-style netbooks on the market featuring multi-touch screens but, at under £400, the Vye V-91015 is one of the cheapest around. The 10-inch screen rotates from the standard laptop form, to enable it to be carried like a tablet, which is where the multi-touch display comes into its own.

It compromises on specs a little, and there's only 1GB of RAM and a 160GB hard drive at your disposal, but you do get a decent touchscreen netbook that weighs only 1.3kg.

3. Asus EeePC Netbook T101MT – £442

touchscreen laptops

If you're looking for a true tablet feel, but with the convenience of a laptop, then the Eee PC T101MT is a fantastic choice. The 10.1-inch touchscreen is tactile, and Asus's built in software helps you get the most from your touchscreen netbook.

ASUS Eee PCs are a pedigree of netbook, with fantastic build quality backed up with supreme portability. The Intel Atom N450 is adequate for most basic web surfing and YouTube video watching, and the 320 GB hard drive is one of the biggest you'll find on any netbook.

4. Asus T91MT – £459

touchscreen laptops

If you've been bitten by the tablet bug, but don't want to do without a keyboard and mouse, then Asus' smaller netbook offering, complete with multi-touch screen will be right up your street.

The T91MT has a petite 8.9-inch screen, which is no bigger than most of the Android tablets that are swamping the market this Christmas. However, instead of Android, you get Windows 7 and a full keyboard. The multi-touch is fantastic, enabling you to fold the screen back and use a range of gestures, as well as using the supplied stylus.

5. Packard Bell Butterfly Touch LX.BL502.011 – £529.95

touchscreen laptops

Continuing the run of touchscreen laptops to arrive on the scene in the first half of this year, Packard Bell has released the Butterfly Touch, which offers full touchscreen usability and up to a claimed eight hours of battery life in a convertible-tablet, clamshell design.

Weighing 1.6kg and featuring an 11.6-inch WXGA screen, it promises to provide ample mobility for frequent travel use. Operating as a standard clamshell laptop when opened, the screen can then be turned 180 degrees and folded down over the keyboard for full tablet use.

6. Toshiba Satellite U500-1EX – £584.97

touchscreen laptops

Toshiba's Satellite U500 Series is aimed at mobile professionals and previous models have impressed us with their blend of style, comfort and quality. The Satellite U500-1EX comes with an impressive range of features and only a couple of flaws that hold it back.

The U500's impressive touchscreen usability and strong range of features lifts it above other laptops of a similar calibre, with the touch-sensitive screen and media bar offering a great means of control. Touch control is responsive and great for simply viewing documents or playing basic games.

7. Acer Aspire 5738PG-644G32Mn – £644.93

touchscreen laptops

The Acer Aspire 5738PG-644G32Mn boasts a 15.6-inch screen that features touch functionality and is designed to make using the laptop as intuitive as possible.

Acer has succeeded admirably in implementing this with the Windows 7 operating system and, while it's obviously early days for the technology on laptops – rather than tablet PCs – this machine is certainly a step in the right direction.

We like the Acer Aspire 5738PG-644G32Mn a lot and while, realistically, you'll be using the keyboard and touchpad as much as you did before, the touchscreen technology is well implemented and very intuitive to use.

8. Acer 1825PT – £679

touchscreen laptops

The new 1825PT is an 11.6-inch netbook with a swivel-style screen that enables you to convert it into a tablet-style device in a jiffy.

The Aspire's swivel-screen multitouch panel features up to 1,366 x 768 resolution, and the machine packs in up to 8GB of RAM, a 1.3GHz Intel Core 2 Duo SU7300 processor, and a 250GB or 320GB hard drive.

The 1825PT also has a 6-cell battery to give you eight hours of work and play time, so you can spend more time getting touchy feely with your laptop.

Buy the Acer 1825PT

9. HP Touchsmart TM2-1010ea – £863.53

touchscreen laptops

The HP TouchSmart tm2-1010ea is another laptop with a swiveling screen that converts into a tablet PC, much like many in our round up.

The touchscreen is well supported by a host of software. Artists can create finger-painted masterpieces with Corel Paint It! Touch, while Magic Desktop provides children with a cartoon-based interface and access to various games and child-friendly applications.

With a strong range of touch software installed as standard, the HP TouchSmart tm2-1010ea has a sharp and well-supported touchscreen display. Its solid build, incredible portability and impressive features round off this strong contender.

Read our full HP Touchsmart TM2-1010ea review

10. Fujitsu Lifebook T4410 – £1115.99

touchscreen laptops

Like the HP TouchSmart tm2-1010ea, this laptop features a screen which twists 180 degrees to convert into a tablet PC. In this form you can hold the machine in one hand while manipulating the touchscreen with your other.

The sharp 12.1-inch screen is quite small in comparison to some other touchscreen laptops, but to counter this, Fujitsu has included a stylus that tucks neatly into the chassis for storage. This can be used instead of your fingers for more accurate interaction, while a pair of configurable buttons on the side can be set up to simulate mouse-button clicks.

The display is extremely sensitive and registers the stylus tip hovering over an inch from the screen, although this does show where you're about to press and helps to minimise mistakes.

Acer reveals Iconia dual-screen laptop

2011-10-20T08:07:00.000-07:00

Here in New York at Acer's Global press event, the company's talking touch. Lots and lots of touch. It'll be introducing a veritable smorgasbord of equipment as the minutes roll on, but it's kicking things off with its Windows 7-based Iconia dual-screen laptop / tablet, a device we've seen before. For all intents and purposes, this is Acer's version of the Toshiba Libretto W105 (or that far-flung ASUS concept we saw at CeBIT 2009), boasting a pair of glossy touchscreens and no hard specifications to speak of. Naturally, you won't find a keyboard here -- rather, a virtual one will emerge from the secondary panel. There's also a fairly slick media management system that's obviously gesture based -- some real potential there.

We'll be digging for details surrounding a price point and release date, but for now, have a gander at the image above and just imagine how it could revolutionize your life.

In related news, the company also teased its new Clear.fi media sharing system. As the story goes, it's a cloud-based system that's designed to play multi-format content over multi-platform devices, enabling any number of gadgets to talk to one another in order to make content visible and shareable with any other device. So far, it looks as if that could apply to movies, games, photos and music, but it's a single-house affair for now. So long as there's a router and a WiFi connection nearby, any Clear.fi-enabled device should be able to share, search and consume.

Update: The full PR is now after the break, and we've gone hands-on with the device right here! We've also scored the specifications -- she's running Windows 7 Home Premium (64-bit) and is equipped with an Intel Core i5-480M / 560M / 580M CPU, up to 4GB of DDR3 memory, a pair of 14-inch multitouch displays (1366x768 resolution), integrated Intel HD graphics (128MB RAM), VGA / HDMI outputs, an inbuilt microphone and a S/PDIF interface. There's also a 320/500/640/750GB hard drive, Acer's CrystalEye webcam (1280x1024 resolution), 802.11b/g/n WiFi, Bluetooth 3.0+HS, integrated 3G WWAN, gigabit Ethernet, a four-cell battery and a total weight of 6.18 pounds. Closing things out, there are a pair of USB 2.0 ports, a single USB 3.0 jack and a one-year warranty.

Latest Communication System

2011-10-09T07:20:00.000-07:00

Unliquited is a new communication system consisting of two main parts, a mobile phone and a server, wireless connected with each other.

This division allows moving the main electronic components like CPU, and memory from the phone to the server which implies that only the basic hardware stays part of the mobile device. The server processes the software and applications that you can transfer to your phone by touching the screen which works as the interface of the server.

This displacement reduces the components inside the phone so that less materials and energy is required to produce and introduce the phone on the consumer market.

There are apertures on the lateral surfaces in the middle of the fixing tapes, which can be used to craft new forms. Wow! A special adapter is required, which will fuel the touch screen with necessary kinetic and thermal energy for successful operation. The productivity and working of Mobikom increases when more elements are connected to the device. So, enjoy the benefits of a mini cell phone and a full sized tablet with Mobikom.Designer Kamil Izrailov

IPOD TOUCH Apple

2011-10-05T10:43:00.000-07:00

“It’s an iPhone without phone calls”, is how few of the reviewers describe Apple iPod Touch. Well, it is the next best against IPhone if it is not within the reach of your pocket levels. It`s always better to start the product by describing it’s key appealing and not so appealing features.
Thinner the better!

Apple`s products are always known to be thinner than their predecessors. The version is 7.2mm in thickness as compared to its older version which was 8.5mm thick. You would feel like you are holding a glass panel in your hand! Surely you know you aren’t!

The volume control:

While the earlier feature is surely and appealing one, this is the one which surely puts you off! This is especially true for the right handed people who have to train themselves to use the player as it is quite difficult to operate the player with the right! Keeping this apart, the keys are too small and almost flat. Also, they are a bit hard to press. Other button which is considerably ignorable is the power button on the top. Nevertheless, the convenience is how often a person uses the button.

Key features which put light on the model include:

Super slim design
Terrific display
Front facing VGA camera for FaceTime
Rear camera for HD video recording
Super fast, iOS 4.1 with App Store
iTunes Store and iBooks Store
Built-in loudspeaker
Gyro+accelerometer,
Excellent battery life

Key features which are likely to put the users off include:
Volume Control Keys
Poor quality still image capture
No FM radio
Poor earphones with original pack
Not enough loudspeaker volume for FaceTime calls

Since we have compared the phone to the IPhone or are calling it a sister concern of the phone, you should be ready to pay a hefty price for same. The product is available in two forms – 32 GB and 64 GB. While the 32 GB model can range anywhere between Rs 15,000 – Rs 20,000, the 64 GB can cost in the range of Rs 20,000-25,000. Now that

Wrap-up:

All in all, the Ipod touch is not a good option for a person who is already using a smart phone. It is however worth an option if the touch one has yet to make a jump from a ordinary handset. This is especially true for its features like HD video shooting, the new Retina Display, and a faster A4 processor which have been a contributing factor in making the product from just “nice to have” to a totally irresistible one.

Virtual Retina Display

2011-09-25T12:46:00.000-07:00

The Virtual Retinal Display (VRD) is a personal display device under development at the University of Washington's Human Interface Technology Laboratory in Seattle, Washington USA. The VRD scans light directly onto the viewer's retina. The viewer perceives a wide field of view image. Because the VRD scans light directly on the retina, the VRD is not a screen based technology.

The VRD was invented at the University of Washington in the Human Interface Technology Lab (HIT) in 1991. The development began in November 1993. The aim was to produce a full color, wide field-of-view, high resolution, high brightness, low cost virtual display. Microvision Inc. has the exclusive license to commercialize the VRD technology. This technology has many potential applications, from head-mounted displays (HMDs) for military/aerospace applications to medical society.

The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality, the image is on the retina of its eye and not on a screen. The quality of the image he/she sees is excellent with stereo view, full color, wide field of view, no flickering characteristics.

Our window into the digital universe has long been a glowing screen perched on a desk. It's called a computer monitor, and as you stare at it, light is focused into a dime-sized image on the retina at the back of your eyeball. The retina converts the light into signals that percolate into your brain via the optic nerve.

Here's a better way to connect with that universe: eliminate that bulky, power-hungry monitor altogether by painting the images themselves directly onto your retina. To do so, use tiny semiconductor lasers or special light-emitting diodes, one each for the three primary colors-red, green, and blue-and scan their light onto the retina, mixing the colors to produce the entire palette of human vision. Short of tapping into the optic nerve, there is no more efficient way to get an image into your brain. And they call it the Virtual Retinal Display, or generally a retinal scanning imaging system.

The Virtual Retinal Display presents video information by scanning modulated light in a raster pattern directly onto the viewer's retina. As the light scans the eye, it is intensity modulated. On a basic level, as shown in the following figure, the VRD consists of a light source, a modulator, vertical and horizontal scanners, and imaging optics (to focus the light beam and optically condition the scan).

The resultant imaged formed on the retina is perceived as a wide field of view image originating from some viewing distance in space. The following figure illustrates the light raster on the retina and the resultant image perceived in space.

In general, a scanner (with magnifying optics) scans a beam of collimated light through an angle. Each individual collimated beam is focused to a point on the retina. As the angle of the scan changes over time, the location of the corresponding focused spot moves across the retina. The collection of intensity modulated spots forms the raster image as shown above

Digital Scent Technology

2011-09-25T12:42:00.000-07:00

Technology has till date be able to use our sense of site and sound quite successfully in bringing virtual reality and nearer to reality. Consequently you have realistic-looking games, and graphic cards that are capable of rendering them; mice that let you experience the terrain you are traversing, whether in an application, on the internet, or on a CD-ROM; and sound and music, thanks to MP3 and the like, which bring alive your experience in the virtual world. Virtual reality has, since the onset several decades ago, been dominated by visual stimuli, with tactile and auditory information research and added to the sense in the latter years.

Olfactor information has been mainly ignored as input to the virtual environment participant, in spite of the fact that olfactory receptors provide such a rich source of information to the human. To enhance this virtual experience, technology now targets on nose and tongue for the experience of smell and taste. That is, you will soon the able to smell and taste the virtual world's offerings, and not just see or hear them.

Now with the digital scent technology we are able to sense, transmit and receive a smell-trough the internet, smell a perfume online before buying them, check to see if food you are buying is fresh, smell burning rubber in your favorite racing game, or sent scented e-cards from scent enable websites. As this technology gains mass appeal , there is no stopping it from entering into all areas of virtual world. Imagine being able to smell things using a device that connects to your computer. Digital scent technologies is making this a reality.

There is a complete software and hardware solution for scenting digital media and user. It includes a personal scent synthesize for reproducing and electronic nose for the detection of the smell. These two peripheral components connected to the computer and the communication network for the transmission of the digitized smell data does comprise the digital scent technology and communication.

Digital scent technology digitizes the scent by digitizing the scent along two parameters the chemical make and its place in scent spectrum then digitized into a small file which can be transmitted to the internet attached to the enhanced web content. Then with the help of digital synthesizer connected to the computer the transmitter scent can be reproduce from the palette of primary odors following the guidelines of the digital file.

Digital scent technologies find its wide range of applications in scentertinment-movies, music and games, in communication which includes websites which is enhanced with scent. It also has its relevance in E-commerce which will make online-shopping compelling and fun. This technology also helps in advertising fields in making the advertisement more memorable and engaging. Many companies working in the field of digital scent technologies are developing a new technology for identifying dementing brain disorders, including Alzheimer's, Hunting tone's, and parkingson's and for differentiating them from other mental disorders. This method is based on detecting the olfactory deficits that are diagnostic of the deminating diseases.

Physiological Aspects Of Smell

Olfaction is defined as the act of smelling, where as to smell is to receive the scent of something by means of the olfactory nerves. Odorants are substances who characteristics can be determined by chemical analysis. A person's olfactory system operates in a fashion similar to other sensing processes in the body. Air bone molecules of volatile substances come in contact with membranes of receptor sells located in the upper part of the nostrils. The olfactory epithelium, the smell organ covers a 4-10 cm^2 area and consists of 6-10 million olfactory hairs, cilia, that detect different smells of compounds. Excited receptors send pulses to the olfactory bulbs, a part of cortex with a pattern of receptors activity indicating a particular scent.

Because the airways are bent and thus the airflow past the receptors normally is low, we sniff something to get a better sensation. In addition to the cilia, the fifth cranial nerve (trigeminal)has free nerve endings distributed through out the nasal cavity. These nerve endings serve as a chemoreceptor and react to irritating and burning sensations. The trigeminal nerve connects to different region of the brain and provides the pathway for initiation of protective reflexes such as sneezing and interruption of inhalation. If the concentration is high enough both the olfactory and trigeminal sensors will be triggered by most odorants.

Space Mouse

2011-09-25T12:03:00.001-07:00

Every day of your computing life, you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment.

Space Mouse is a professional 3D controller specifically designed for manipulating objects in a 3D environment. It permits the simultaneous control of all six degrees of freedom - translation rotation or a combination. . The device serves as an intuitive man-machine interface

The predecessor of the spacemouse was the DLR controller ball. Spacemouse has its origins in the late seventies when the DLR (German Aerospace Research Establishment) started research in its robotics and system dynamics division on devices with six degrees of freedom (6 dof) for controlling robot grippers in Cartesian space. The basic principle behind its construction is mechatronics engineering and the multisensory concept. The spacemouse has different modes of operation in which it can also be used as a two-dimensional mouse.

How does computer mouse work?

Mice first broke onto the public stage with the introduction of the Apple Macintosh in 1984, and since then they have helped to completely redefine the way we use computers. Every day of your computing life, you reach out for your mouse whenever you want to move your cursor or activate something. Your mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately

Inside a Mouse

The main goal of any mouse is to translate the motion of your hand into signals that the computer can use. Almost all mice today do the translation using five components:

SPACEMOUSE

Spacemouse is developed by the DLR institute of robotics and mechatronics.

DLR- Deutsches Zenturum far Luft-und Raumfahrt

4.1 Why 3D motion?

In every area of technology, one can find automata and systems controllable up to six degrees of freedom- three translational and three rotational. Industrial robots made up the most prominent category needing six degrees of freedom by maneuvering six joints to reach any point in their working space with a desired orientation. Even broader there have been a dramatic explosion in the growth of 3D computer graphics.

Already in the early eighties, the first wire frame models of volume objects could move smoothly and interactively using so called knob-boxes on the fastest graphics machines available. A separate button controlled each of the six degrees of freedom. Next, graphics systems on the market allowed manipulation of shaded volume models smoothly, i.e. rotate, zoom and shift them and thus look at them from any viewing angle and position. The scenes become more and more complex; e.g. with a "reality engine" the mirror effects on volume car bodies are updated several times per second - a task that needed hours on main frame computers a couple of years ago.

Parallel to the rapid graphics development, we observed a clear trend in the field of mechanical design towards constructing and modeling new parts in a 3D environment and transferring the resulting programs to NC machines. The machines are able to work in 5 or 6 degrees of freedom (dot). Thus, it is no surprise that in the last few years, there are increasing demands for comfortable 3D control and manipulation devices for these kinds of systems. Despite breathtaking advancements in digital technology it turned out that digital man- machine interfaces like keyboards are not well suited for people to use as our sensomotory reactions and behaviors are and will remain analogous forever.

4.2 DLR control ball, Magellan's predecessor

At the end of the seventies, the DLR (German Aerospace Research Establishment) institute for robotics and system dynamics started research on devices for the 6-dof control of robot grippers .in Cartesian space. After lengthy experiments it turned out around 1981 that integrating a six axis force torque sensor (3 force, 3 torque components) into a plastic hollow ball was the optimal solution. Such a ball registered the linear and rotational displacements as generated by the forces/ torques of a human hand, which were then computationally transformed into translational / rotational motion speeds.

The first force torque sensor used was based upon strain gauge technology, integrated into a plastic hollow ball. DLR had the basic concept centre of a hollow ball handle approximately coinciding with the measuring centre of an integrated 6 dof force / torque sensor patented in Europe and US.

From 1982-1985, the first prototype applications showed that DLR's control ball was not only excellently suited as a control device for robots, but also for the first 3D-graphics system that came onto the market at that time. Wide commercial distribution was prevented by the high sales price of about $8,000 per unit. It took until 1985 for the DLR's developer group to succeed in designing a much cheaper optical measuring system.

4.2.1 Basic principle

The new system used 6 one-dimensional position detectors. This system received a worldwide patent. The basic principle is as follows. The measuring system consists of an inner and an outer part. The measuring arrangement in the inner ring is composed of the LED, a slit and perpendicular to the slit on the opposite side of the ring a linear position sensitive detector (PSD). The slit / LED combination is mobile against the remaining system. Six such systems (rotated by 60 degrees each) are mounted in a plane, whereby the slits alternatively are vertical and parallel to the plane. The ring with PSD's is fixed inside the outer part and connected via springs with the LED-slit-basis. The springs bring the inner part back to a neutral position when no forces / torque are exerted: There is a particularly simple and unique. This measuring system is drift-free and not subject to aging effects.

The whole electronics including computational processing on a one-chip-processor was already integrable into the ball by means of two small double sided surface mount device (SMD) boards, the manufacturing costs were reduced to below $1,000, but the sales price still hovered in the area of $3,000.

The original hopes of the developers group that the license companies might be able to redevelop devices towards much lower manufacturing costs did not materialize. On the other hand, with passing of time, other technologically comparable ball systems appeared on the market especially in USA. They differed only in the type of measuring system. Around 1990, terms like cyberspace and virtual reality became popular. However, the effort required to steer oneself around in a virtual world using helmet and glove tires one out quickly. Movements were measured by electromagnetic or ultrasonic means, with the human head having problems in controlling translational speeds. In addition, moving the hand around in free space leads to fairly fast fatigue. Thus a redesign of the ball idea seemed urgent.
