The document discusses two input devices: the Evo Mouse, which turns any flat surface into a touchpad using infrared sensors and image processing, and the Magic Cube projection keyboard, which projects a virtual keyboard that can be typed on using infrared detection of finger movements. Both devices connect via USB and work on various operating systems. They provide portable, space-saving alternatives to traditional mice and keyboards.

1.Sensor module
2.IR light source
3.Pattern projector

25. TTeecchh……
 Sensor module
-operates by locating user’s finguers in 3D
space & tracking intended keystrokes.
 IR-Light source
-emits infrared light
-helps to recognize hand movements &
pressing of keys

26. TTeecchh……..
 Pattern projector
-image projected on flat surface
-projected image of QWERTY keyboard

27. WWoorrkkiinngg
 emits infrared light from the lower end to
detect objects such as fingers.
 object passes through the area
illuminated by the infrared light source,
any infrared light reflecting off the object
is detected by the sensor.
 To perform operation movement of
fingure neccessry.
27

28. CCoonnttii……....
 No problem of detecting fingure while
infrared reflected wave in appropriate
amount
 amount of reflected infrared light is too
high, the keystroke become too sensitive
or a “hovering” effect may occur.
 Hovering: keystroke is recognized before
your finger touches the projection
surface.

29. AAddjjuussttiinngg sseennssiittiivviittyy
 Magic Cube features sensitivity
adjustment for better accuracy
 To increase sensitivity, press and hold
FN key and tap .> key
 To lower sensitivity, press and hold FN
key and tap < key

 1. Avoid direct sunlight.
 2. Avoid low color temperature light
source, such as tungsten, halogen, or
incandescent lamp.
 3. Avoid uneven or irregular surfaces.
Place the product on flat surfaces.
 4. Avoid a table or surface that is as
transparent or reflective as glass or
mirror.
