Motion based

        MOTION  BASED GAMES

We know about motion based games in Android,Windows,iphone  like Asphalt series. Most of us are interested in these motion based games and me too crazy about it.These motion based games works with the help of sensors .

How it works?

Motion based games  mandatorily needs Accelerometer sensor  which are also known as G-sensors.Depending on games,types of sensers  are needed.Accelerometer  measures tiltation angle and linear acceleration.So that’s how this sensor got name as accelerometer sensor.It also makes mobile screen portrait to landscape i.e., however we rotate  smartphone ,the picture or photo doesn’t change it’s position.we  can also say that it follow gravity.Comparing to accelerometer sensor we have more sensors but all sensors are not used.Fundamental  sensors like Accelerometer,Gyroscope,Magnetic sensors and Pressure sensors.

Gyroscopes

Gyroscope sensors are also known as Gyros. Gyros measures angular rotation rate about one or more axis.It doesn’t depend on anything like accelerometer depends on gravity.

Magnetic Sensors

Magnetic compass sensor  tells about directions(NEWS).Magnetic sensors are useful whenever one navigates  to  new place. Magnetic sensors are also known as E-compasses.

Pressure Sensors

Pressure sensors measures pressure in terms of altitude.This will be useful when user moves to different floors in same building.The apps which supports pressure sensor are known as location based applications(pressure).

Technology behind touch screen working

HOW TOUCH SCREEN WORKS:
     
   Touch screen works on one of three principles:-

 1. Resistive system 
 2. Capactive System
 3.Surface Acoustic Wave


RESISTIVE SYSTEM:

It consists of glass panel which is covered with conductive and resistive metallic layer. These two layers are held apart by spacers. Electrical current moves through these two layers.When touch the screen ,voltage difference appeared at that spot, immediately OS recognises coordinates of spot and does it's operation.

CAPACTIVE SYSTEM:

It consists  a layer on galss panel which stores electrical charge. when we touch the screen,it transfers some of charge to user .Thereby capactive layer charge decreases,within short span OS recognises the cordinates where the charge is decreased and applies it operation overthere.

SURFACE ACOUSTIC WAVE( pen tip):

This works with two transducers( one receiver and one transmitter). Electrical signal is sent from one to other transducer.

When user touch the screen ,passing electrical signal is disturbed.

Receiving transducer  recognises wave disturbance and tells to OS, then OS traces the spot and does it's operation overthere.

eg: Smartphones uses pen sticks.
