Gaze-Contingent Visual Presentation Based on Remote Saccade Detection

Abstract

Pursuing new display techniques based on insights into human visual perception can reveal new possibilities for visual information devices. Here, we propose a novel information presentation technique that exploits the perceptional features during rapid eye movements called saccades by using a fast remote eye-measuring method. When light sources are fixed on a vertical line, and the flashing pattern is changed quickly during a horizontal saccade, 2D images can be perceived due to spatio-temporal integration in the human vision system. We use this phenomenon to present 2D images with only one-dimensional light sources, and to show these images even in midair. The flashing cycle and flash timing of light sources are important elements in developing the design theory for this display technique. The flashing cycle determines the maximum resolution of a perceived 2D image. The flash timing is a crucial issue for our purpose because 2D images are perceived only when the timing of the saccade coincides with the flash timing. Therefore, in this paper, we describe the relationship between a flashing cycle and the maximum resolution of a perceived 2D image, and then propose a concise saccade detection method. By using this method, saccades can be detected and the light sources can be flashed within the saccade interval as it occurs in real time, and 2D images can be successfully presented.

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.…”

Development of 480-fps LED display by use of spatiotemporal mapping

“…When adjacent pixel information is sequentially shown at each pixel in the LED panel, we will perceive a filled image because our small involuntary eye movements fill the gap between LED lamps with the adjacent pixel information. With combination with our eye movements, typically saccades, temporal emitting sequence of LEDs can expended spatially [10], [11]. If this technique is applicable for 3D stereoscopic display of parallax barrier type, afterimages may fill black stripes in the viewed image.…”
