It can be applied to various sports or dance performances even if the target moves so quickly. Although a gray scale high-speed projector is used in this video, a color expression can be implemented by using a new color high-speed projector we have developed　recently.

The projector will be commercialized by companies in near future. I hope DPM system will be transferred to commercial companies.

Beautiful expression onto moving or deforming 3D objects can be implemented by using combination of the 24bit high-speed color projector and a high-speed 3D shape measurement. Last demo of cats is also 24 bit color.

Perfect projection without misalignment has been obtained by a key technology based on synchronization among position of gaze point, high-speed projector, and Galvano mirror which controls projection point. We will make a color version of the system in near future.

Everybody can feel this projection phenomenon at high reality.

By our technology, we applied to a moving 3D rigid body using well-aligned dynamic projection mapping with a high-speed projector based on high-speed physical simulation without latency and real-time adaptation to environmental lighting.

[Ishikawa Group Laboratory @IshikawaLab_e]

Although basic principle was a technology used in the deformation lamps developed by NTT Communication Science Laboratories,

In addition, we developed high-speed actuators and high-speed displays. We can develop new high-speed intelligent systems by using 1ms high-speed devices including encoders and force sensors which are originally high-speed.

[Ishikawa Group Laboratory @IshikawaLab_e]

Under the concept that all robot sensors should have 1ms sampling rate, our laboratory and Shimojo laboratory have developed high-speed tactile sensors, high-speed vision sensors including 3D vision, and the high-speed proximity sensor.
