Accelerated and Optimized Search of Imperceptible Color Vibration for Embedding Information into LCD images
Shingo Hattori, Takefumi Hiraki
Large, high-resolution displays are installed throughout the city as public displays. By superimposing invisible information on the images of these displays, large numbers of devic…
ChromaGazer: Unobtrusive Visual Modulation using Imperceptible Color Vibration for Visual Guidance
Rinto Tosa, Shingo Hattori, Yuichi Hiroi +2
Visual guidance (VG) is critical for directing user attention in virtual and augmented reality applications. However, conventional methods using explicit visual annotations can obs…
HaptoFloater: Visuo-Haptic Augmented Reality by Embedding Imperceptible Color Vibration Signals for Tactile Display Control in a Mid-Air Image
Rina Nagano, Takahiro Kinoshita, Shingo Hattori +3
We propose HaptoFloater, a low-latency mid-air visuo-haptic augmented reality (VHAR) system that utilizes imperceptible color vibrations. When adding tactile stimuli to the visual…
Measurement of the Imperceptible Threshold for Color Vibration Pairs Selected by using MacAdam Ellipse
Shingo Hattori, Yuichi Hiroi, Takefumi Hiraki
We propose an efficient method for searching for color vibration pairs that are imperceptible to the human eye based on the MacAdam ellipse, an experimentally determined color-diff…
