| dc.description.abstract | Meta CEO Mark Elliot Zuckerberg emphasized at the Facebook Connect conference in 2021 that the Metaverse is the next frontier, and said that ＂from now on, we will prioritize the Metaverse, not Facebook,＂, the main force of future development will be on headset “Oculus”. At the same time, stocks of digital chip-related companies have soared, and people are looking forward to the day when the Metaverse actually takes shape.
Head-mounted devices are an indispensable existence in the Metaverse. After wearing the device, users will have an ＂immersive＂ experience. However, the device has a huge fatal disadvantage. After long-term use, it will feel more tired than ordinary 3C devices, and even have symptoms such as dizziness, headache, nausea, and vomiting. Such devices have been developed for more than 20 years, but there is still no objective evaluation criterion.
This paper proposes a new head-mounted device evaluation system, which mainly uses the high dynamic range Shack-Hartmann wavefront detector developed in our laboratory, and uses a customized super large 23mm square microlens array (MLA) and large format the wavefront detector is used as a measurement tool. The object to be measured uses the mixed Reality (MR) device provided by the medium-intensity photoelectricity. By displaying a white spot with a diameter of 20 pixels on it, and using program control to change the position of the light field to complete different views. Field measurement. Finally, use the angle of incident light to push back the imaging position, and obtain various information such as light intensity and aberration of the light source.
The measurement system is a preliminary structure, and there is still a lot of room for improvement in the future. With the advancement of science and technology, it can have more different objects to be measured, and generate more reference data, in order to establish an objective and general evaluation of head-mounted devices. | en_US |
