Gaze-contingent visual presentation technique with electro-ocular-graph-based saccade detection

Abstract

When a single column of light sources flashes quickly in a temporal pattern during a horizontal saccade eye movement, two-dimensional images can be perceived in the space neighboring the light source. This perceptual phenomenon has been applied to light devices for visual arts and entertainment. However, a serious drawback in exploiting this perceptual phenomenon for a visual information display is that a two-dimensional image cannot be viewed if there is any discrepancy between the ocular motility and the flicker timing. We overcame this drawback by combining the saccade-based display with an electro-ocular-graph-based sensor for detecting the saccade. The saccade onset is measured with the electro-ocular-graph-based sensor in real time and the saccade-based display is activated instantaneously as the saccade begins. The psychophysical experiments described in this article demonstrates that the method that we used can detect saccades with low latency and allows the saccade-based display to convey visual information more effectively than when the light sources continuously blink regardless of the observer's eye movements.

Multimodality with Eye tracking and Haptics: A New Horizon for Serious Games?

“…In videogames, real-time performance is important, so the latency of detecting a saccade needs to be as small as possible for seamless experience. New saccade detection methods have been proposed for reducing latency, therefore, leading to the possibility of achieving real-time performance and enhanced visual experience [39][40][41]. Furthermore, using saccadic behaviour to predict fixation location can provide the capacity for seamless implementation of LOD graphic rendering [42], as previously applied in high performance flight simulators.…”

Aesthetic Aspects of Technology-Mediated Self-awareness Experiences

“…In the interface technology, I and my colleague (H. Ando) and supervisors (T. Maeda and S. Tachi) focused on the information that is discarded and leveraged this information to develop a novel visual information presentation method [2,11,12]. To describe the principle of the technology, let us first consider the scheme illustrated in Fig.…”

Two-Dimensional Grouping Affects Perisaccadic Perception of Depth and Synchrony

“…However, little attention has been paid to the perception of images induced by a saccade [ie an image presented on the retina during a saccade at the speed of the eye movement-hereafter called a saccade-induced image (SiI)]. The perceptual features of the SiI remain poorly understood, although the SiI has been applied for a novel visual display (Watanabe, Maeda, & Ando, 2012) and in the field of visual arts (Bell, Parks, & Post, 1986). Here we examine how the object's configuration in a SiI affects the perception of the SiI, as investigated for perisaccadic spatial compression of flashed stimuli (Matsumiya & Uchikawa, 2001;Sogo & Osaka, 2005).…”
