Human computer interaction system and human computer interaction method

A human computer interaction method, comprising:

• obtaining first motion sensing data based on a first sensor, wherein the first motion sensing data is related to a first operating portion of a user and generated based on a determination whether an analysis result of a motion of the first operating portion based on one of a first motion sensor and a first image sensor is reliable, the first sensor comprises the first image sensor and the first motion sensor, the first motion sensor is acted with the first operating portion of the user, and the first image sensor captures images of the first operating portion of the user, and the step of obtaining the first motion sensing data further comprises:
• using the images captured from the first image sensor as the first motion sensing data in response to the analysis result of the first operating portion of the user based on the first image sensor being reliable;
• and
• using data obtained from the first motion sensor as the first motion sensing data in response to the analysis result of the first operating portion of the user based on the first image sensor being unreliable;
• obtaining second motion sensing data, wherein the second motion sensing data is related to a second operating portion of the user different from the first operating portion and generated based on a second sensor;
• and
• triggering an event according to both the first motion sensing data and the second motion sensing data.
