The Wistron Corp invention works as follows
An adjustable virtual-reality device includes a display module with a display unit and an image capture unit. It also has a driving unit for lateral movement, as well as a control unit. The first and second display modules display a respective first and second image. The first and second image capturing units detect the two positions of pupils on two eyeballs. The control unit calculates the distance between two pupils based on the two positions and then controls the lateral driving modules to drive the first and second display modules in a sideways direction. This increases comfort during use.
Background for Adjustable Virtual Reality Device capable of Adjusting Display Modules
1. “1.
The present invention is a virtual-reality device and, more specifically, an adjustable virtual-reality device that can adjust display modules.
2. “2.
A virtual-reality device uses two displays to provide images for the two eyes of a person in order to create a 3-dimensional effect through binocular disparity. The positions of the two displays in a virtual reality device conventionally cannot be adjusted to match the pupil distance between a user’s eyes. It can easily cause dizziness or discomfort. Another conventional virtual reality device is capable of manually adjusting the distance between two displays to reduce discomfort. Since the users adjust the distances between two displays based on visual feelings, it is not possible to match the pupil distance of two user’s eyes exactly. This causes discomfort when the virtual reality device is worn for a short time. The distance between two displays, two eyeballs, or two glasses lenses is not adjustable. Two displays can easily interfere with the eyeballs and lenses of the virtual reality device when the user is wearing it. This causes discomfort. It is also not possible to customize the device for users with a high binocular dispersion.
The present invention aims to solve the problems by providing an adjustable virtual-reality device that can be adjusted with display modules.
The present invention discloses a virtual reality adjustable device that can adjust display modules in order to achieve this objective. The adjustable virtuality device includes a base, housing, first display module with a first detecting module, second display module with a second detection module, at least one driving transverse module and a controller. The base is located inside the housing. The first display module can be moved on the base to display a first picture. The first detecting unit includes a capture module for a primary position of the first pupil in a single eyeball. The second display module can be moved on the base to display a second picture. The second detecting unit includes a capturing module for detecting the second position of an eyeball’s second pupil. The at least transverse driving modules are used to drive the first display module or the second display module in a transverse motion. The control unit is electrically linked to the atleast one transverse module, the first and second image capturing units. The control unit controls at least one transverse module in order to drive the display modules to move independently or synchronously according to the relation between the pupils based on the position of the pupil of the first and second displayed module detected by the image capturing module.
The present invention discloses a virtual reality device that can be adjusted to adjust display modules in order to achieve this objective. The adjustable virtuality device consists of a housing, base, first display module with a first detecting unit, second display module with a secondary detecting unit, longitudinal driving module and control unit. The base is located inside the housing. The first display module can be moved on the base to display a first picture. The first detecting module includes a distance-detecting unit that detects a distance between the display module of the first eyeball and a lens or glasses matching a second eyeball. The second display module can be moved on the base to display a second picture. The second detecting module includes a distance-detecting unit that detects a distance between the second display module, a lens corresponding to a secondary eyeball and a distance between the second display modules. The longitudinal driving unit is used to drive the first and second display modules in a longitudinal direction. The control unit is connected electrically to the longitudinal drive module, first distance detecting units, and second distance detecting units. The control unit drives the longitudinal driving module so that the first display and second display modules move in the longitudinal direction according a reference distance generated from the first distance and second distance.
The adjustable virtual reality device uses the first and second image capture units to detect the two positions where the first and second pupils of the eyeball are located. It then controls the transverse driving unit to drive the display modules to move in the transverse direction based on the distance between the eyeballs of the eyeballs of the eyeballs of the eyeballs of first and second pupils or the positions between the eyeballs of first and second pupils. This allows for the transverse distance of the display modules to correspond to the distance between them It increases comfort when using. The adjustable virtual reality device of this invention also uses the first and second distance detecting units to detect the distances between the display modules and the eyeballs or lenses of the glasses that correspond to the eyeballs, as well as the distances between the display modules and second eyeballs or second lenses of the glasses that correspond to the eyeballs, and then controls the longitudinal driving unit to drive both the display modules to move in the longitudinal direction based on the distances. This prevents the display modules from interfering either with the It also increases comfort when used.

The first image capture unit 170 detects the first position of a pupil in the first eyeball. The second image capture unit 180 detects the second position of a pupil in the second eyeball. The control module 16 calculates the distance between the first and second pupils based on the first and second positions and then controls the transverse driving unit 14 to move the first display module 11, and the 2nd display module 12, along the transverse X direction according to this pupil distance. The first display module 11 moves from the two positions in FIG. The first display module 11 and the second display module 12 move from two positions shown on FIG. The first display modules 11 and 12 are moved away from each other so that the transverse distance between them is equal to the pupil distance. This can prevent the user feeling dizzy or uncomfortable.
The two transverse modules 14 can adjust the first display module 11, and the display module 12, to positions that correspond to the positions of the pupil 170, and pupil 2 detected by the image capturing units 170, and 180, respectively.
