39 Phygital Hardware & Software Challenges Transition from smartphone-first to AR glasses-first mobile computing. Release of a mass-market end user device (near-eye display device, likely in the form of AR glasses) with the appropriate characteristics: wide viewing angle cones (field of view), long-lasting battery life, proper panel resolution, comfortable form factor, advanced imaging performance, brightness and resolution density among others. The latter two tackle the issue of displaying AR objects in bright light or outdoor daylight, when the picture in glasses does not provide a sufficient level of quality. AL Vergence-accommodation conflict (VAC): instead of a stereo sensation when viewing 3D objects in real life, AR glasses use fixed display plane where different rendered contents for each eye is adopted, which leads to visual fatigue and discomfort, sabotages stereo acuity, and distorts perceived depth. Improving the quality of spatial tracking (SLAM) to ensure that 3D objects perfectly fit into any space in a very fast OF PHYGITE and invisible for the end user manner. AT Independence of tracking quality from lighting conditions, movements and external shaking: overall subjects ST stability is not lost, there is no shaking of objects and their displacements. Enhancement of device performance, which can be solved by transferring all processing to the cloud via 5G (now processing mainly takes place on the edge device (smartphone), which causes restrictions in use. 2021
