#Multitouch screens sense software
"It's really how the software is used that makes touch screens usable," says Bruce Gaunt, a mechanical engineer at Product Development Technologies, a product development firm that designs and integrates touch-screen technologies for manufacturers of cell phones and laptops.

The glass touch surface is also more durable, and capacitive technology is more forgiving of surface scratches.Īpple's major innovation with the original iPhone was figuring out how to track the actions of two simultaneous touches, which enabled the development of the iPhone's now-familiar gestures: swipe, rotate and pinch/expand. Projected capacitive screens use a glass touch surface that offers a higher level of transparency than the plastic layer used in resistive technology, resulting in brighter colors. Capacitive touch-sensing technology requires a person's finger (or a specially designed capacitive stylus) to disturb the electrical field unlike resistive designs, it doesn't work with an ordinary stylus or other inanimate objects. The touch panel sits on top of the display media (most commonly a liquid crystal display).
Resistive screens could track the position of just one finger at a time.Īpple chose a competing technology, projected capacitance, which responds to a light touch and can also sense a finger as it enters the electronic field above the touch surface - a technique called proximity sensing. A touch, not a pressīefore the iPhone, most touch screens used pressure-sensitive, resistive touch panels, which required that the user physically press down on the screen. Check back next week for another sizzling display technology.

The device is called TV (TTTV), and it uses a carousel of 10 flavour canisters that spray in combination to create the taste of a particular food.Editor's note: This is the first of a four-part series on red-hot display technologies to watch in 2011. Similarly, a Japanese professor has developed a prototype lickable TV screen that can imitate food flavours, a step towards creating a multi-sensory viewing experience. It has been developing for over a decade, where researchers use electro-vibration to make for a better sensory experience on a smooth touch surface. It’s not the first time we’ve heard about this technology. We have been field testing and providing valuable feedback to the researchers at IIT-M on improving the functionality of the technology." We aim to make a small device, similar to a computer mouse, on everyone's desk to add to the experience. To advance this technology, IIT Madras has collaborated with Merkel Haptics, a start-up housed at the IIT Madras research park.ĬEO of Merkel Haptics, PV Padmapriya, said, “The prototype from Touchlab can be made into a product in a year. Their expectations are different by looking at the images online. Also, around 30 percent of product returns are due to the mismatch of user experience. Further, to make this work, electric fields in the touchscreen are controlled via a physical phenomenon known as 'electroadhesion’.Īccording to a lead researcher and a professor in the department of Applied Mechanics, M.Manicannan, this technology can take online shopping to the next level as we can touch and feel things before we buy them, especially clother. There are no moving parts in iTad however, it has an in-built multitouch sensor that detects finger movement and surface friction and adjusts via software.
It is the next generation of in-touch display technology, said IIT Madras. This new technology is known as iTad - (interactive Touch Active Display), and it can mimic textures such as gritty surfaces and crisp edges. Currently, touchscreens can only sense the position of one’s fingers but offer no feedback. Researchers at the Indian Institute of Technology Madras have claimed to develop a new touchscreen display technology that allows users to feel the texture of images as their finger goes across the touch surface.
