View-independence and user-independence are two fundamental requirements for hand posture recognition during natural human-robot interaction. However only a few research concerns on the two issues simultaneously. The difficulty for natural gesture-based human-robot interaction lies in that appearances of the same hand posture vary with different users from(More)
This paper presents a general gaze control algorithm for humanoid robot head. Gaze control is an essential visual behavior for human-robot interaction. Calculation of the distance to fixation point is a first step to accomplish coordinated head-eye movements on humanoid robot head. We solved the problem of obtaining depth information under the condition of(More)
The MEMS-based micro surgical tools are a kind of new devices applied in the minimally-invasive surgery. This paper introduces their application background and basic technology first, and then lays emphasis on the typical research accomplishments in the world. Finally, the research activities in China and some of the difficulties about the work are(More)
