Virtual displays for 360-degree video
In this paper we describe a novel approach for comparing users' spatial cognition when using different depictions of 360degree video on a traditional 2D display. By using virtual cameras within a game engine and texture mapping of these camera feeds to an arbitrary shape, we were able to offer users a 360-degree interface composed of four 90-degree views, two 180-degree views, or one 360-degree...
متن کاملLearning Compressible 360{\deg} Video Isomers
Standard video encoders developed for conventional narrow field-of-view video are widely applied to 360° video as well, with reasonable results. However, while this approach commits arbitrarily to a projection of the spherical frames, we observe that some orientations of a 360° video, once projected, are more compressible than others. We introduce an approach to predict the sphere rotation that...
متن کاملAnalysis of 360° Video Viewing Behaviours
In recent years there has been a significant interest in Virtual Reality applications, including 360° videos. 360° video streaming via the network typically consumes a lot of bandwidth due to the file size of these kind of videos being up to 6 times larger than traditional videos. Due to the nature of 360° videos, a user only utilizes about 20 % of the transmitted data; that is, the part of the...
متن کامل360-Degree Video Head Movement Dataset
While Virtual Reality applications are increasingly attracting the attention of developers and business analysts, the behaviour of users watching 360-degree (i.e. omnidirectional) videos has not been thoroughly studied yet. This paper introduces a dataset of head movements of users watching 360-degree videos on a Head-Mounted Display (HMD). The dataset includes data collected from 59 users watc...
متن کاملWeb Accessibility Requirements for Media Players
Video Content continues to strenghten on the Web, because of that fact, it is neccessary to include video content with suitable accessibility requirements to be used by all people. User Agent (such as player, browse), also have to include accessibility requirements. In this paper a set of basic guidelines is included for profesionals who want to embed video players on their Web.
