Adaptive display control of exhibits in a distributed haptic museum

This work proposes an adaptive display control scheme for touchable exhibits in a distributed haptic museum in order to improve the output quality of haptic media as well as audio and visual media. The proposed scheme carries out LoD (level of detail) control of exhibited objects and proactive transfer control of information files. The LoD control of objects dynamically changes the granularity of object display according to the network load, CPU processing load, and importance of an object, which is determined by the distance, direction, etc. from a user's viewpoint to the object. The proactive transfer control of information files transmits the object's haptic information (e.g., weight and form), visual information (e.g., color and pattern), and explanatory information (e.g., voice, video, and text) from a server to clients in advance according to the file size, network load, and CPU processing load. A method of implementing the scheme is discussed in the paper.
