Mobile computing devices facilitate the completion of tasks in all aspects of our daily lives. However, mobile displays have been recognized to have adverse impacts on our vision, and they may even cause severe injures to our eyes. Mobile devices cause visual discomfort, not only because of screen glare but also as a result of handheld shake and vibration. To address the aforementioned concerns, we assessed the implementation of an anti-shake mechanism for mobile display to provide users with a comfortable interaction experience and to minimize negative side effects of screen vibrations. The overall process of implementing this mechanism includes analyzing the accelerometer data, predicting the magnitude of device displacement, and adjusting the position of the display area to compensate for vibrations. In this paper, we propose a fuzzy inference model for motion prediction and display stabilization. We verified this model with tumbling E eye exams and subjective 10-point scale questionnaires. The experimental results reveal that the anti-shake mechanism successfully decreases sight fatigue when applied to mobile devices used in dynamically changing environments.

“…The measurement methodologies of visualization quality on a more objective level (i.e., angular resolution of a display system) are given by the International Display Measurement Standard [27]. The related publications of Kovács et al [28] [29] [30] investigate both subjective and objective quality of light field visualization, with emphasis on spatial and angular resolution [31] [32] [33]. In this paper, angular resolution refers to the content itself, which is the ratio of the number of source views and the utilized FOV of the display, as stated in Section I.…”

Abstract-Light field visualization has progressed and developed significantly in the past years. At the time of this paper, light field displays are utilized in the industry and they are commercially available as well. Although their appearance on the consumer market is approaching, many potential applications of light field technology have not yet been addressed, such as video streaming. In this paper, we present our research on the dynamic adaptive streaming of light field video. In order to evaluate the presented concept of quality switching, we carried out a series of subjective tests, where test participants were shown light field videos containing stallings and switches in spatial and angular resolution.

“…This applies to the experiments of Cserkaszky et al [15] [16] and Darukumalli et al [17] as well. As a counter example, Kovacs et al [18] used 2.7H. Greater viewing distances did appear in literature, but smaller ones not even once, due to the front-projection nature of the system.…”

At the time of this paper, research on the quality of lightfield visualization is continuously gaining momentum, as the excellence in visual performance shall be one of the key enablers of the emergence and long-term presence of this technology on the consumer market. Experiments on perceived quality began in parallel with the appearance of commercially available light-field displays. As the techniques of subjective quality assessment on these displays are not standardized yet, certain parameters may greatly vary, such as viewing conditions. Although most of the current research efforts in this area address forms of static visualization, light-field video is also an essential target of quality evaluation. In this paper, we introduce the results of an experiment investigating the viewing conditions of light-field video quality assessment. The tests directly compare the perceived horizontal motion parallax of static viewing positions with motion patterns. The visual quality of the test conditions was degraded by the reduction of content spatial and angular resolution, as they both affect the smoothness of the horizontal motion parallax.
