SENSORS USED IN GAMES

By Wusqa Waqar

What are sensors and how are they used in games?

•A sensor is a converter that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrumen

•A game might track readings from a device's gravity sensor to infer complex user gestures and motions, such as tilt, shake, rotation, or swing.

•Sensors create a connection between the controller and the wii. The player sends commands through the controller. They are sent as signals and the sensors of the wii , for example, inputs the signal and does what it is told to do.

Example Of Game Sensors:Tilt sensors Tilt sensor used in a

joystick• A tilt sensor can measure

the tilting in often two axes of a reference plane in two axes. Typical applications can be found in the industry and in game controllers. They are used for:

i. Indicating pitch and roll of vehicles, sail boats, and aircraft.

ii. Monitoring the boom angle of cranes and material handlers.

iii. Measuring the "look angle" of a satellite antenna towards a satellite and etc.

Where Are Game Sensors Used?Kinect sensor Example

• Kinect is a motion sensing input device by Microsoft for the Xbox 360 video game console and Windows PCs. The device features an "RGB camera, depth sensor and multi-array microphone running proprietary software", which provide full-body 3D motion capture, facial recognition and voice recognition capabilities.

• It was made to interpret specific gestures, making completely hands-free control of electronic devices.

• The software technology enables advanced gesture recognition, facial recognition and voice recognition.

Advantages: •Helps to control

things properly. •Functions are

easily and quickly done.

•They can easily detect if there’s any problem with the game.

•Wireless sensor network are easier to control and avoid a lot of wiring.

•Disadvantages: •Often devices with good game sensors, like playstations or wii, are expensive.
