00:18I am involved in AR-VR system development at R&D Center, Sony Group Corporation.
00:24I also work at the R&D Center, where I develop microdisplays.
00:28The COVID-19 pandemic has dramatically changed both our lifestyles and work styles.
00:35One such change is an increase in demand for remote capabilities.
00:40To collaborate and share experiences remotely, high-resolution technologies for realistic
00:45images and low-latency systems for seamless video are necessary.
00:54The VR head-mounted display for demonstration can project a realistic high-definition 3D space
01:01without pixelization.
01:06Our HMD achieves 4K with one eye and 8K with both eyes.
01:11This is the demonstration video.
01:19The video on the right is an image from the demonstration.
01:23From detailed letters and material textures, you can tell the image is so close to the reality.
01:31With VR, we have expanded the display using lenses to extend the image throughout the visual
01:38field of human eyes.
01:40If pixel dots are recognized, users feel like they are looking at display due to pixelization.
01:45For realistic visual experience, it requires many dots to be invisible when they are enlarged.
01:52The panel size also needs to be small enough to fit into the limited form factor.
01:58For these two requirements, we developed a 4K OLED micro-display, which is an ultra-high 4K per
02:05inch resolution.
02:09This 4K OLED micro-display has more than double the number of dots compared to smartphone OLED
02:16and reduces the panel size by almost 20 times.
02:20For high number of dots in a smaller display, we use Sony's fine processing and advanced packaging
02:27technologies gained from CMOS image sensor.
02:31For high image quality, we leverage the OLED device and circuit technologies.
02:38The real-time image display with low latency aligned with user's head movement is vital to
02:45to provide a 3D appearance and a sense of distance in the VR viewing.
02:50Normally, it takes about 0.1 second for processing.
02:53To avoid a user feels dizzy, the processing time must be shorter than 0.01 second.
03:00Perceived delay is reduced by combining multiple sensor data and latency compensation technology.
03:06The image is converted according to the latest position or direction of user's head before
03:11display projection.
03:14The combination of high-resolution OLED displays and low-latency HMD would be leveraged in a
03:21broad range of domains in addition to games and videos such as design where detailed texture
03:26depiction is required or virtual communication where you can feel the other person is in the
03:32same room or live entertainment to capture the detailed facial expressions of artists or in
03:38medical trainings and manufacturing operation supports.
03:43We aim to achieve smaller, lighter, ultra-high-resolution head-mount displays and to create spaces for
03:50people can interact over the network.
03:52Ultimately, we would like to create an astonishing sense of immersion for remote collaboration and sharing.
03:58Thank you for your time.
