Speech Title: Aerial Display Based on High-speed Visual Servoing Using Dynamic Optical Components
Abstract: Recently, aerial display technologies have fascinated people. Dynamic projection mapping on drones is one way to achieve such aerial displays. In this presentation, a method to achieve dynamic projection mapping on a flying screen by drones using high-speed optical gaze controller is introduced. The high-speed optical gaze controller is an optical component consisting of automated rotating mirrors that has been developed by our research group and allows millisecond control of the optical axis direction. This system can control both the gaze direction of machine visions and the projection direction of projectors. We applied this system to continuous projection on a flying screen that was attached on a drone. A prototype system was developed and successfully demonstrated dynamic projection mapping on a screen attached to a flying drone at a distance of about 36 m, which indicated the effectiveness of the proposed method.

Speech Title: User Performance based on the Effects of Low Video Latency between Visual and Haptic Information in Immersive Environments
Abstract: In recent years, many immersive devices have emerged that enable intuitive interaction by projecting the user's body movements into a virtual reality space. However, these devices have an inherent delay between input and output, causing a temporal mismatch between the user's visual information and physical sensation. In existing research, the effect of delay in a highly immersive environment in which the self is projected has not been sufficiently investigated, and there are no concrete indicators.
In this study, we developed a system with a minimum delay time of 4.3 ms from image capture to projection using a high-speed camera and a high-speed projector, and a delay time that can be controlled with a resolution of 1 ms. Using the proposed system, we performed a pointing task based on Fitts' law to investigate the effect of delay on user performance. Experimental results show that performance begins to decline when the delay exceeds 24 ms. In the case of the steering task, in which the user moves the finger along a tunnel-like path, performance dropped when the delay exceeded 64 ms. Thus, this system, which enables the measurement of acceptable delay limits for video presentation, can be applied as an indicator in the design of future interactive immersive devices and in research and development for virtual reality.
