Keyboard is a projection keyboard that is
projected and touched on any surface.
What can you do with a Virtual
Keyboard? :
What can you do with a Virtual Keyboard?
The ground breaking Virtual Keyboard,
uses state of the art infrared & laser
technology to project a full-size keyboard
onto any flat surface.For the first time
mobile device users can actually type
normally on a virtual keyboard , enabling
them to work quickly and effectively,
taking the pain and frustration out of
existing minuscule keyboards and
handwriting recognition software.
How does the Virtual Keyboard Work?
:
How does the Virtual Keyboard Work?
The keyboard watches finger movements
and translates them into keystrokes in the
device. A system called the P-ISM will
combine the virtual technology with a
small video projector to create a portable
computer about the size of a fountain pen.
Technology How does it work?
Technical Terms :
Technical Terms Projection Module – A
template is created of the desired interface
and is projected onto the adjacent interface
surface. This template is produced by
illuminating a specially designed highly
efficient holographic optical element with
a red diode laser. Micro-illumination
Module – An infa-red plane of light is
generated just above, and parallel to the
interface surface. This light is invisible to
the user and hovers a few millimeters
above the surface. Sensor Module –
Reflected light from user interactions with
the interface surface is passed through an
infa-red filter and imaged onto a CMOS
image sensor in the sensor module.
