Description
The Virtual Laser Keyboard (VKB) leverages the power of
laser and infrared technology and projects a full-size
keyboard onto any flat surface. As you type on the laser
projection, detection technology based on optical
recognition enables the user to tap the images of the keys,
complete with realistic tapping sounds, which feed into the
compatible Bluetooth-enabled PDA, Smartphone, laptop or PC.
Unlike many small snap-on keyboards for PDAs, the Virtual
Laser Keyboard provides a full-size QWERTY keyboard. It is
also smaller and more convenient to use than the
folding-type keyboards made by some manufacturers and
similar to them in functionality. There are no mechanical
moving parts whatsoever in the Virtual Laser Keyboard. It
provides a projected image that is the perfect portable
input device for PDAs. It's similar in responsiveness to
regular keyboards.
The light weight device weighs two ounces and is similar in
size to a disposable cigarette lighter. The Virtual Laser
Keyboard includes a self-contained, rechargeable lithium ion
battery. It provides the Virtual Laser Keyboard with its own
internal power supply, so it doesn't drain any battery power
from the PDA or PC. The battery lasts two to three hours,
more than enough time to do some instant messaging and SMS
messaging from the handheld device or to update calendar and
phone book entries.
Technology
Step 1: Template creation
(Projection Module)
A template of the desired interface is projected onto the
adjacent interface surface. The template is produced by
illuminating a specially designed, highly efficient
holographic optical element with a red diode laser. Note:
the template serves only as a reference for the user and is
not involved in the detection process. In a fixed
environment, the template can just as easily be printed onto
the interface surface.
An infra-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.
When the user touches a key position on the interface
surface light is reflected from this plane in the vicinity
of the key and directed towards the sensor module.
Reflected light from user interactions with the interface
surface is passed through an infra-red filter and imaged on
to a CMOS image sensor in the sensor module. Custom hardware
embedded in the sensor chip (the Virtual Interface
Processing CoreTM) then makes a real-time determination of
the location of the reflected light. The processing core can
track multiple reflection events simultaneously and can thus
support both multiple keystrokes and overlapping cursor
control inputs.
Step 4: Interpretation and
communication (Sensor Module)
The micro-controller in the sensor module receives the
positional information corresponding to the light flashes
from the sensor processing core, interprets the events (e.g.
keydown, keyup, mouse or touchpad control etc..) and
communicates them through an appropriate interface to
external devices.
