IntroductionIntroduction This is the device that emits infrared

light to detect fingers as they keyboard

HistoryHistory

21

Quarty keyboard-It is based on microprocessor &

microcontroller

Virtual KeyboardVirtual Keyboard Smaller in size & faster Uses sensor technology User work on surface Device detect movement of fingures Input data by typing on image

Technology usedTechnology used System having 3 modules

1.Sensor module

2.IR light source

3.Pattern projector

24

Tech…Tech… 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

25

Tech….Tech…. Pattern projector

-image projected on flat surface

-projected image of QWERTY keyboard

26

WorkingWorking 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

Conti…..Conti….. 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.

28

Adjusting sensitivityAdjusting sensitivity 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

29

Condition to avoidCondition to avoid 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.

30

Conti…Conti… 5. Avoid placing any objects within the

space between the main unit and the laser projected keyboard layout.
