Joshua Blake is back with an update to his Kinect PowerPoint Control project...

Kinect PowerPoint Control v1.2

Updated for Kinect SDK v1.7...

This project shows how to use the Kinect SDK to do basic gesture recognition to control PowerPoint.



  1. Compile and run the application
  2. Point the Kinect at you and stand at least five feet away
  3. You can see yourself in the application window and the three ellipses will track your head and hands.
  4. Extend your right arm to activate the "right" or "forward" gesture. Extend your left arm to active the "left" or "back" gesture. These gestures will send a right or left arrow key to the foreground application, respectively.
  5. Run your PowerPoint show so PowerPoint is the foreground application, and the right and left gestures will go forward and back in your deck.

The ellipses grow and change color when your hand exceeds the threshold of 45 centimeters. The gestures will only activate once as your hand exceeds the threshold, and only one of the gestures can be active at once. You must bring your hand back closer to your body to activate the gesture a second time.
The gestures will also work for any other application. For example, open Notepad and type some text then use the gestures to move the cursor left or right one character at a time.

Speech recognition

By default voice recognition is disabled due to false positives, but you can uncomment the call to the StartSpeechRecognition() in MainWindow_Loaded() to enable speech recognition. The recognizer is set up to recognize and respond to the following commands:

  • computer show window
  • computer hide window
  • computer show circles
  • computer hide circles
