After unveiling Surface (touch screen) technology for large size displays, Microsoft has joined hands with Mitsubishi to work on a small display. According to Microsoft Touch, input on small screen of a mobile device is problematic because a user’s fingers occlude the graphical element he wishes to work with. LucidTouch is a mobile device that addresses this limitation by allowing the user to control the application by touching the back of the device. Sounds very similar to the patent filled by Apple last month. Looks like everyone is working on the same touch technology but with slight modifications. LucidTouch also supports multi-touch input, allowing user to use all the fingers simultaneously to operate the device. According to Microsoft’s initial study, results indicate that many users found touching on the back to be preferable to touching on the front, due to reduced occlusion, higher precision and the ability to make multi finger input. Well 5 years back Microsoft’s study also found out that everyone will prefer Tablets to Laptops, and two years back they said UMPC will replace most ultra portable laptops but we are yet to see that happen.
