IRTOUCH Offers New Solution with an infrared touch screen interface

Beijing IRTOUCH Systems Co., Ltd. successfully made technical breakthrough, will deliver new infrared multi-touch product with the most thin border in the world at COMPUTEX 2012.

IRTOUCH Systems Co., Ltd, the world leading touchscreen provider, has been focus on research, development, and manufacturing of infrared and optical touch products for many years, provides customized solutions to different customers in various industries.

IRTOUCH has made significant structural changes, developed super-thin boarder infrared touch screens, the width of boarder is reduced to 14mm, and the thickness of product is reduced to 4.1mm while height of touch side is lower than 1.6mm. This new design provides simplified view and better integration capacity with monitor manufacturer, increased end user experiences and touch responsiveness.

Besides the structural changes, IRTOUCH implements multi-touch capacity on all product lines. The new large and super-large infrared touch screen with multi-touch, multi-people operation and multi-gestures will also be available in this COMPUTEX 2012. As the only large screen provider in China mainland, IRTOUCH build a solid foundation for those customers who need large amounts of products.

IRTOUCH has the world leading infrared and optical touch technologies, provides high quality human-machine interactive touch solutions with rapid respond speed, high stability, long lifetime, free of maintenance and free of drift.

Touch Screen Technology Research To Become More Genius

The touch screen interface on a device typically used to respond to taps and also a touch of the two-dimensional, but sheering forces across the display, could open up a new paradigm of tablet and phone control, research has suggested. Rather than conjuring up pop-up toolbars and other screen-dominating UI elements, a press-and-pull gesture could be used to cycle through options, select different colored pens or drawing tools, or perform speedy copy & paste.

The project, handiwork of Chris Harrison and Scott Hudson of Carnegie Mellon University, describes “Using Shear as a Supplemental Input Channel for Rich Touchscreen Interaction.” Their prototype uses a moving panel on top of a touchscreen tablet device, which can be pulled in multiple directions if the user presses down and drags their finger across it. That, it’s argued, introduces a whole new input method that next-gen platforms could take advantage of.

“Touch input is constrained, typically only providing finger X/Y coordinates. To access and switch between different functions, valuable screen real estate must be allocated to buttons and menus, or users must perform special actions, such as touch-and-hold, double tap, or multi-finger chords. Even still, this only adds a few bits of additional information, leaving touch interaction unwieldy for many tasks. In this work, we suggest using a largely unutilized touch input dimension: shear (force tangential to a screen’s surface). Similar to pressure, shear can be used in concert with conventional finger positional input. However, unlike pressure, shear provides a rich, analog 2D input space, which has many powerful uses” Harrison and Hudson

So, in the researchers’ demo apps, by using sheering forces in one of several directions, different options can be selected; a touch and sheer-up gesture can copy text, with a touch and sheer-down then pasting it. A prototype music player controls play/pause and track skip with sheering movements, while circular sheer-dragging motions can be used for scrolling or zooming.

One obvious practical issue is the nature of the hardware: the current prototype, for instance, requires a screen which can move on top of the device itself. However, some touchscreen manufacturers – such as Neonode - are already working on sensors which can pinpoint not only points of touch but angle of touch, pressure and more. That would presumably support the researchers’ sheer system, without requiring an awkward panel on top.

Touche: Smart Touch Sensing Technology Developed

Just about everybody in the United States is familiar with capacitive touchscreens, but not with how they work. A small electric voltage is applied to the screen, and when you touch it (or nearly touch it) the voltage changes.

This is because the capacitance of the system changes, because of your presence. Normally this technology in a binary fashion, where just one frequency is monitored, and if it changes enough, a touch is recognized.

Researchers at Carnegie Mellon University and Disney Research, Pittsburgh have expanded on this technology by making a touch system that monitors multiple frequencies, and therefore multiple kinds of touches.

By monitoring multiple frequencies, the Touché system is able to distinguish between touch events with different number of fingers, or different parts of the body. In one of the demos for the system, a table was setup to track whether someone had their hands on it, their elbows, and even if someone was sitting near it, without touching the table. To achieve this, the system has to process a lot of data, which is now possible thanks to the ever smaller processors being developed for mobile and embedded technologies.

It may still be awhile before we get smart doorknobs, which recognize different grasps, but the technology is almost completely accurate right now, so the wait may not be long. Of course, it will likely be smartphones where this first becomes relevant as a way to control the device while it is still in your pocket.
