E-Ball is designed to be placed on two stands , opens by simultaneously pressing and holding the two buttons located on each side
It has a button when you press this button a projector will pop and it focus the computer screen on the wall which can be adjusted with navigation keys.
Whenever you press the keyboard button, it is projected optically on the flat surface and, as the user touches the image of the key, the optical device detects the stroke and sends it to the computer.
Virtual keyboard basically consists of three components:-
Module serves as the eyes of the
Keyboard Perception technology.
The Sensor Module operates by
locating the user's fingers in
3-D space and tracking the
IR-light source:-The Infrared Light Source emits a beam of infrared light. This light beam is designed to overlap the area on which the keyboard pattern projects. This is done so as to illuminate the users fingers by the infra-red light beam.
These devices use dichroic mirrors to split the light from the input source into red, green, and blue components. Each then passes through the corresponding panel, where pixels form an image. The three colors are then recombined in a prism before being projected through a lens. LCD projectors use separate panels for each color because it results in better color saturating than using a single panel for all three.
There are two primary methods by which DLP projection systems create a color image, those utilized by single-chip DLP engine, and those used by three-chip-engine. In projection cube industry, Most of manufacturer uses
