iTad is unlike anything else on the market today because it combines multi-touch sensing with haptics on the same layer.” When we add feedback, the interaction with computers becomes experiential. Manivannan said“Currently computer touchscreens can only sense your position of your fingers on the screen, but offers no feedback. Home automation, medical, industrial and gaming,Īid for visually challenged, among other areasĮxplaining how this ‘iTad’ differs from contemporary technologies, Prof. We have been field testing and providing valuable feedback to the researchers at IIT Madras on improving the functionality of the technology.”Īutomotive, Consumer Electronics, and Digital Signage Padmapriya, CEO, Merkel Haptics, said, “The prototype from the Touchlab can be made into product in an year’s time.Our aim is to make a small device, similar to a computer mouse, on everyone’s desk to add to the experience. Around 30 per cent of returns to the online shopping are due to the mismatch of user experience, their expectation is different by looking at the images online.”Įlaborating on the current status of ‘iTad’ and a timeline for hitting market with possible application in the real world, Dr. The technology can take online shopping experience to the next level.We can touch and feel things before we buy from e-commerce platforms. Manivannan, Department of Applied Mechanics, IIT Madras,“This is the era of iTad. Highlighting the impact this technology could have on Electronic Appliances, Prof. Merkel Haptics, a start-up incubated at the IIT Madras Research Park, has been working with the Touchlab researchers to take the technology forward.

By controlling electric fields via a physical phenomenon known as ‘electroadhesion,’ the software modulates friction locally as fingers travel across a smooth plane. Instead, an in-built multi-touch sensor detects the movement of the finger and surface friction is adjusted via software. A new level of interaction comes alive on smooth physical surfaces. Through the use of software, the researchers can create different textures such as crisp edges, switches and rich textures that range from smooth to gritty. Existing touchscreens can only sense your location of finger touch.Ĭalled ‘iTad,’ for interactive Touch active display, it is the next generation in Touch Display technology. Surface capacitive touch screens are especially popular in amusement fields such as casino gaming due to its high durability and visibility.Indian Institute of Technology Madras Researchers have developed a new touchscreen display technology through which a user can feel the textures from images as the finger moves across the touch surface. They are used on ATM, ticketing machine, kiosk, POS, office automation, factory automation, arcade games, and medical and food industry. Surface capacitive touch screens tend to be employed for applications that are large size (over 12inch), used by general public, and requiring high-quality looking, high resolution and high durability.Recently, tolerance for noise has been improved with various methods such as noise shielding. Surface capacitive touch screen is likely to be affected by noise.Surface capacitive technology does not support multi-touch.Some surface capacitive touch screens support pen writing, but they usually does not support combination use of finger touch and pen writing. Some surface capacitive touch screens may detect touches by thin-gloved hand, but they do not support the combination use of bare finger and gloved finger. Basically, surface capacitive can detect touches by fingers only.Surface capacitive has high resolution and high response speed.Parallax is minimized in surface capacitive.Surface capacitive does not get affected by moist, dust, or grease.Surface capacitive is structurally tough as it is made of one sheet of glass.Visibility is high because structure is only one glass layer.Surface capacitive sensor can respond to light touch, and no pressure force is needed for detection.Surface capacitive technology is suitable for large size monitors.
