Method and system for establishing standard calibration model of wearing comfort of VR head-mounted equipment

Abstract

The invention discloses a method for establishing a wearing comfort standard calibration model of a VR head-mounted device. Each preset part of the head surface applies a test pressure that changes gradually according to the preset gradient; receives the feedback signal of each tester's judgment on whether the test pressure of each gradient is comfortable, and detects the human body induction on the head surface of each tester in real time Pressure; record the test pressure and calculate the expected value of the human body's induced pressure, and establish a data model based on this; load the data model on the mean structure model, and solve the model induced pressure on the surface of the mean structure model; according to the model induced pressure and human body induced pressure The difference between the expected values ​​of modifies the property of the mean structure model to bring the two into line. The present invention can make the VR head-mounted device adapt to the wearing requirements of most people, and ensure high wearing comfort.

Description

technical field [0001] The present invention relates to the technical field of VR, in particular to a method for establishing a wearing comfort standard calibration model of a VR head-mounted device. The invention also relates to a system for establishing a standard verification model of wearing comfort of a VR head-mounted device. Background technique [0002] With the development and application of VR, AR and other virtual reality technologies and augmented reality technologies, and the continuous emergence of head-mounted VR, AR and other visual products, people have put forward higher requirements for the wearing comfort of such head-mounted products. The collection and analysis of the somatosensory pressure data of the human head is the key technology to solve the design of this type of head wearing comfort. The data collection and analysis of sensor body pressure has also become a hot topic in the field of scientific research. This research has important research valu...

Problems solved by technology

[0004] In the existing technology, it is often only possible to manufacture VR head-mounted devices based on experience first, and then improve the VR head-mounted devices according to the actual experience feedback of users in the after-sales link. However, this is not conducive to improving user experience. And the user's personal experience is very subjective. When the current user's experience is better, the rest of the user's experience may be completely different.
