cell 3D laser ‘virtual keyboard’
The CL850 is portable input device adopting the company’s sensor module which recognizes locations and movements of fingers and transmits the inputs recognized by the sensor to user’s device. As a successor of CL800BT, it adopted Bluetooth and USB connectivity with which you can connect the virtual keyboard to your desktop pc and other mobile devices such as laptop and PMP.
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.
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.
ase 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 Canesta layout or they can develop custom layouts to suit their unique product, branding, and customer needs.
The ‘projection keyboard’ is made possible through the incorporation of the 3D Electronic Perception Technology (EPT). This innovation enables everyday devices to “see” the world around them so they can perceive and interact with it. The EPT tracks your finger movements and translates them into keystrokes in the device.
Different from traditional digital cameras that record images in 2 dimensions so humans can see, EPT collects images the way that machines need to see in 3 dimensions. With the integration of Celluon’s technology in small, low cast, computer chips, virtually any kind of electronic device can perceive and interact with its immediate environment.
Future applications of this technology might include automobiles that can see and avoid obstacles before an
accident occurs, video games that sense the player’s movements without the need for a controller, and even home security systems that can easily recognize the difference between a member of the household and an intruder. Just imagine the new possibilities in an era in which machines and devices are no longer”blind”!
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).
