Multipoint technology allows pressure simultaneously in several points on a touch screen, its success in the market comes from the hand of Apple and its revolutionary iPhone, in which technology made his debut with an original interface based on gestures and multiple keystrokes.
Microsoft, similar to other companies is not shown to be unrelated to the technology, it in fact works long surface, a multimedia touch surface the size of a table based on the same idea, and in all likelihood the next version of its mobile operating system, Windows Mobile 7, It can be compatible with multi-touch screens.
In this field, other companies such as RIM and your BlackBerry Storm are beginning to integrate touch screens, the case that we are discussing is not a conventional touch screen, but the presentation of a new interface called multipoint SideSight, in which its use goes beyond the own screen of the device.
To present SideSight, Microsoft has used a smartphone HTC Touch with sensors that detect movements of the fingers around the mobile phone, with the advantage to be able to use the system without requiring a touch screen. Can orient their use not only terminals, but other devices such as watches and MP3 players, which can not integrate touch screen, because of its size.
The demonstration showed a virtual cube that revolved as the user moved his fingers around the device. The idea of Microsoft It is to combine this technology with touch screens, we already know, so accordingly we do not lose the possibilities of touch, as well as add new capabilities.
The system is based on infrared rays (proximity sensors) that depart from the phone to the outside, are spaced 10 mm between them, and capture the interference of our fingers by placing them on their way. Users can use the device with both hands, without even touching the phone, making displacement vertical and horizontal, rotations, and even with a quick movement toward the device could be interpreted as a ‘click’.
The system presents an initial problem, only detects a single finger, since you can not consistently differentiate between fingers that have an impact on the control, Microsoft He decided to leave it at that. An important detail but it is overshadowed by the possibility that we can see perfectly what happens herein, without our hands or gestures hinder vision.
Looking to the future, there are some things to fix, is intended to improve energy consumption, improved sensors, and prepare a prototype specific, in addition to studying more applications, all necessary to succeed commercially.
