Kinect is an electronic device that tracks body movement without contact. It was developed by Microsoft and released in 2010. There have been two main versions - Kinect for Xbox, which uses a time-of-flight camera for precise depth sensing, and Kinect for Windows, which has gone through several iterations to update its infrared sensor technology. Kinect uses infrared and depth sensing to detect joints, facial expressions, and other body metrics to enable full-body control of applications and games.

• Version 2
- Second-generation Kinect(based on the same core technology as Kinect
for Xbox One) will be released in summer 2014

9. Kinect for Xbox
• Uses wide-angle time-of-flight camera(three times more accuracy than its
previous version using IR sensor)
• Processes 2GB/s to read its environment
• Detect heart rate, facial expression, 25 individual joints(including thumbs),
weight put, speed of movements, etc…..
• Provide voice commands(for navigation, starting games, waking the
concole from sleep mode)

15. IR Sensor
• IR Projecter – Projects a grid of IR dots
• IR Sensor – Detects IR dots and compute the
depth image
• RGBCamera – Similar to a standard webcam

• InfraRed

16. IR Sensor
IR dots
IR Sensor can
detect them
but we can’t

17. ToF CameraVS IR Sensor
ToF Camera
• Compute the depth precisely
• Better resolution
• Expensive
• Big
• Limited Distance
• Cannot detect LED under the sunlight
IR Sensor
• Compute the depth less precisely
• Lower resolution
• Cheap
• Small
• Cannot detect the depth under the sunlight
too
