In this paper, the concept of the adaptive multimode interactive interface based on embedded equipments is proposed and its implementation on digital STB is also brought forward, accompanying with the concrete design of the program step and the implementation details of the key component. The adaptive multi-mode interactive interface effectually improves the performance of human-computer interaction on digital STB. This not only effectively promotes the process popularized in the digital STB but also provides a good reference to human-computer interaction on embedded equipments.
