How it Works:
The projection laser displays the keyboard layout, measuring approx. 241 x 106 mm, onto any opaque flat surface. Keystrokes are recognized and then relayed via an invisible infrared layer combined with an optical sensor.
The recognition process works as follows: When the user presses a key on the projected keyboard, the infrared layer is interrupted. This produces UV reflections that are recognized by the sensor in three dimensions, allowing the system to assign a coordinate (keyboard character).
Features and Benefits
Small, easy-to-integrate components: Its compact size and lower power consumption allows manufacturers to integrate the Projection Keyboard directly into their devices without significantly increasing the size or power consumption of the device.
Portability - Fast and accurate data input. The large keys and familiar layout of the Projection Keyboard allows for input speeds greater than that of 50 words-per-minute with error rates similar to that of a standard physical keyboard, thus setting a new benchmark in mobile input performance.
Ease of Use: Projection Keyboard provides users with a comfortable, near fatigue-less way of entering data into their mobile devices. Projection Keyboard can also help reduce the ergonomic risk factors associated with other input alternatives by reducing strain on the wrists
Dual mouse and keyboard functionality: Since the Projection Keyboard Perception Chipset works by optically tracking finger movements rather than registering the physical switches of a regular keyboard, users can use the same surface for both keyboard data entry and mouse functionality.
Customizable solution: Projection Keyboard functionality can serve as a highly visible and distinct differentiating feature in the competitive industry of mobile devices. Device manufacturers can choose to deploy Projection Keyboard using the default Canasta layout or they can develop custom layouts to suit their unique product, branding, and customer needs.
