3
Stewart Platform Consists of a fixed base and a moving platform connected by six extensible actuators. Provide sensation of motion by tracking desired trajectory. Incorporate wash-out filter that improves the capability and performance. Current Achievement
4
System Diagram of Motion Platform Current Achievement
5
Stewart Platform Demo Current Achievement
6
Human Figure Recognition(1) 1.Extract foreground object from background image. 2.Identify if the foreground object is a human figure. Current Achievement
7
Human Figure Recognition(2) Current Achievement
8
Human Limb Tracking(1) Future Work Use calibrated camera system to track the configuration of upper body limbs.
9
Human Limb Tracking(2) Detect head position first. Use 3D kinematic model to help recover the posture of upper body. Future Work Head Torso Left Upper Arm Left Forearm Right Upper Arm Right Forearm shoulder elbow neck
10
Human Limb Tracking(3) Future Work The human limb configuration can intuitively manipulate objects displayed in large screen or immersive environment.
11
Context-Aware Interactive Media Humans are good at conveying ideas to each other because they use context information to increase the conversational bandwidth. Context-aware interactive applications can make HCI more natural. Context-awareness is the essential feature of next generation interactive media. Future Work
12
Intelligent Agents for Interactive Media Traditional Media : Direct Manipulation System only do something if we explicitly tell it to. Interactive Media : Agent-based Interaction We work with computer as peers, each carry out parts of work. Agents can do works according to their experts, or negotiate with other agents on behalf of user. Agents can issue appropriate commands to the actuator / display according to user’s intention autonomously. Asking other agents to help (via Web Services), if the commands are out of local agent’s ability.(Ex: Hotel Reservation, emergent situation…) Future Work
