Cypress Semiconductor is a company that makes the TrueTouch capacitive touchscreen. As reported by Slashgear, the company is now working to add hover support to their finger controlled touchscreens. This would allow a screen to recognize the presence of a user"s finger before it actually makes contact with the screen.
In the video below, you will see how the technology in action. TrueTouch Project Manager, Sherif Hanna, explains the benefits of such a technology and demonstrates how it works. In the real world, for example, the technology could be used to enlarge a link as your finger closes in on it. This could greatly help users with bigger fingers, or those who use smartphones will smaller screens.
Cypress plans to have hover detection available for manufacturers sometime during the second quarter of this year.
