HMD (Head Mounted Display) drive control structure under parametrical adaptive control

Abstract

The invention provides an HMD (Head Mounted Display) drive control structure under parametrical adaptive control. The HMD can automatically adjust display parameters (such as brightness, contrast, perspective rate and the like) according to the change of using environments of a user, the requirements of comfort degree and definition of the HMD under various using environments of the user can be furthest met, and the adjustment participated with manual operation is not needed; and aiming at some other defects (such as existing a huge-sized control box and multiple data cables) of the traditional HMD product with adjustable parameters, an optimal design is carried out for the traditional HMD product by adopting a scheme of integrating the wireless data transmission with a hardware module, and thus the advantages of mobility and portability of the traditional HMD product are further enhanced.

Description

technical field [0001] The invention belongs to the field of electronic information, relates to electronic engineering and optoelectronic engineering technology, in particular to a novel head-mounted display (HMD) drive control structure. Background technique [0002] Head Mounted Display (HMD), also known as Helmet Mounted Display (HMD), is a near-eye display device (Melzer, Moffitt 1997). The special human-computer interaction characteristics of HMD make it widely used in scientific research, education, medical treatment, games, industry, military and other fields in combination with augmented reality and wearable computing technology. The basic HMD is composed of the image source subsystem (including the image source device and its drive control circuit), the optical subsystem, and the support subsystem. It can also be extended with auxiliary functional devices such as headsets and cameras on the basic HMD to form a multifunctional HMD. [0003] HMDs using OLED / Lcos and...

Problems solved by technology

However, various HMDs of this type sold on the market have poor adjustability (mostly only have brightness adjustment function), only support user manual key adjustment, single human-computer interaction function (only have display function), and multi-functional products. It needs a huge external control box, bulky lead wires and many cables, etc., such as the Z800 of Emagin Company in the United States: although it supports display brightness adjustment, it only provides users with manual adjustment mode, due to the movement of the head-mounted display itself The stability and portability have resulted in the continuous change of its use environment, so the Z800 cannot automatically adjust the display parameters in real time when the environment changes. To meet the user's requirements for comfort and clarity in various environments, It is necessary to manually adjust the display parameters, which brings great inconvenience to the user (especially in the mobile environment); at the same time, Z800 (most of the existing head-mounted displays that support display parameter adjustment) has an external The larger control box and a large number of cables bring great inconvenience to users and reduce its advantages in mobility and portability
