Abstract
Technology is presented for providing feedback to a user on an ability of an executing application to track user action for control of the executing application on a computer system. A capture system detects a user in a capture area. Factors in the capture area and the user's actions can adversely affect the ability of the application to determine if a user movement is a gesture which is a control or instruction to the application. One example of such factors is a user being out of the field of view of the capture system. Some other factor examples include lighting conditions and obstructions in the capture area. Responsive to a user tracking criteria not being satisfied, feedback is output to the user. In some embodiments, the feedback is provided within the context of an executing application.
