This study compared the visual fatigue caused by two smartphone displays with different blue light distributions based on a 90-min video watching task. The results showed that decreased when using low-blue display, reflected subjective questionnaires, ocular and electroencephalograph signals. display low is recommended for reducing fatigue.

Special Section on the Joint Call for Proposals on High Efficiency Video Coding (HEVC) Standardization THE FIRST commercially successful digital video compression standard emerged 20 years ago in the form of Recommendation ITU-T H.261. MPEG-1 and H.262/MPEG2 video (the latter was jointly standardized by ITU-T and ISO/IEC) were then developed very soon thereafter, and they resulted in an explosi...

Human gestures contain certain characteristics and meanings in communication and represent a link between intention and body. This paper describes a pilot study investigating the role of ancillary musical gestures in understanding musical meaning from the listener’s standpoint. We conducted a perceptual experiment using motion-capture recordings of musicians. Participants were presented video r...

Tiled projector arrays are effective at meeting the needs for scalable, cost effective, higher resolution displays. Increases in PC performance have allowed small tiled displays to be driven from a single PC with multiple graphics cards. In this paper we present a system for automatically aligning the Windows Desktop of a tiled display. This system consists of three primary procedures: detectin...

Advancements in graphics hardware have allowed development of hardware-accelerated imaging displays. This paper reviews techniques for real-time simulation of arbitrary visual fields over still images and video. The goal is to provide the vision sciences and perceptual graphics communities techniques for the investigation of fundamental processes of visual perception. Classic GazeContingent Dis...

This paper presents a system for the automated inference of complex mental states from observed facial expressions and head gestures in video. Head actions are identified from image-based pose estimation. Facial actions, including asymmetric ones, are extracted from motion, color and shape parameters. A multi-level dynamic Bayesian network classifier models complex mental states as a sequence o...

the video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. the objective of this study is to assess the video quality using image features extraction without using reference video. rmse values and processing ...

projection display, is a room-sized, five-screen system that can display both computer graphics and video images. Several Cabins connected via a broadband network form the Cabinet system. Cabinet includes video avatars—a key new technology for sharing virtual worlds. Using video avatars, we have experimentally evaluated the ability to express positional information between distant users. I mmer...

L ow-cost public displays are growing in popularity, appearing in our workplaces, in public spaces, and on university campuses. However, due to their pervasiveness, they present many challenges: How do people encounter public displays? What are the key usability and design factors when creating and deploying applications for such displays? How do local communities adopt pervasive displays, and ...
