Title: Low-Latency Projectors for Dynamic Interactive Systems
Keywords: Low-latency display, augmented reality, high-speed vision, projection mapping
Abstract: One of the key challenges in developing interactive systems using projectors is how to minimize display latency. A straightforward approach is to increase the video frame rate, but this significantly raises the overall system cost and complicates content production. Alternatively, by carefully exploiting the mechanism of the projection device, it is sometimes possible to reduce the perceived latency without increasing the frame rate. This talk will introduce implementations that enable this approach, with a particular focus on systems using Digital Micromirror Devices (DMDs). The talk will also present projection mapping systems designed for dynamic scenes, along with their applications.
