Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2 together, fig. 1 is a block diagram of a head-mounted display apparatus 100 according to an embodiment of the invention. As shown in fig. 1, the head-mounted display apparatus 100 includes a display device 10, a processor 20, and a sensor unit 30.
The display device 10 includes a display screen 11 and an optical lens 12. The display screen 11 is used to output a display screen including a pointer. The optical lens 12 is located in an output path of the display. That is, when the user wears the head-mounted display device 100, the optical lens 12 is located on a side of the display screen 11 close to the eyes of the user, so that the display image output by the display screen 11 will pass through the optical lens 12 before reaching the eyes of the user.
As shown in fig. 2, the sensor unit 30 is configured to detect a distance between the optical lens 12 and the display screen 11 to obtain a detected distance D1. Wherein, the sensor unit 30 is disposed on the display screen 11 and the optical lens 12.
The processor 20 is configured to adjust the sensitivity of the pointer movement at least according to the detection distance D1 detected by the sensor unit 30.
In some embodiments, the processor 20 adjusts a pointer sensitivity factor (factor) according to at least the detected distance detected by the sensor unit 30 to achieve the adjustment of the sensitivity of the pointer movement. Wherein the moving distance of the pointer on the display screen 11 is equal to the physical moving distance of the input device 200 (shown in fig. 4) multiplied by the pointer sensitivity factor, and when the pointer sensitivity factor is changed, the moving sensitivity of the pointer is also changed accordingly, so that the adjustment of the pointer moving sensitivity can be realized by adjusting the pointer sensitivity factor.
The optical lens 12 is movable according to a user operation, for example, when the user adjusts the diopter of the head mounted display device 100, the optical lens 12 moves to different positions, and when the positions of the optical lens 12 are different, different corrective power effects can be generated. Therefore, when a user, such as a user with myopia, uses the head-mounted display device 100, the position of the optical lens 12 is adjusted, and at this time, the sensitivity of the pointer movement can be automatically adjusted according to the detected distance between the optical lens 12 and the display screen 11, so as to be suitable for different people.
As shown in fig. 2, in an embodiment, the processor 20 obtains an actual distance W1 between the display screen 11 and an exit pupil position C1 of the display device 10, calculates a difference between the actual distance W1 and the detected distance D1 to obtain an exit pupil distance Dc, calculates a ratio of the exit pupil distance Dc to a first preset distance J1 to obtain a target pointer sensitivity factor, and adjusts a current pointer sensitivity factor to the target pointer sensitivity factor. That is, the target pointer sensitivity factor is equal to the ratio of the exit pupil distance Dc to the first preset distance J1. The exit pupil position C1 is a position where the user's eyes are located when the head-mounted display device 100 is worn by the user. The first preset distance J1 is the distance between the optical lens 12 and the exit pupil position C1 when the optical lens 12 is at the initial position. In some embodiments, an eyepiece is disposed at the exit pupil position C1, which may be referred to as an eyepiece at exit pupil position C1.
That is, in the illustrated embodiment, the processor 20 calculates the target pointer sensitivity factor according to the formula Dc/J1. Wherein, as previously described, Dc-W1-D1, J1 is the first predetermined distance. When the optical lens 12 is at the initial position, the optical lens 12 does not perform power correction, and the display image viewed through the optical lens 12 by the user is a normal display image without performing vision correction.
In another embodiment, the processor 20 determines the correction degree Y1 of the optical lens 12 to the human eye at the current position according to the detected distance D1, calculates the zoom factor of the display viewed through the optical lens 12 according to the detected distance D1 and the correction degree Y1, determines the reciprocal of the zoom factor as the target pointer sensitivity factor, and adjusts the current pointer sensitivity factor to the target pointer sensitivity factor. The detecting distance D1 and the correcting degree Y1 have a preset corresponding relationship, and the correcting degree Y1 corresponding to the detecting distance D1 can be obtained according to the corresponding relationship. The preset corresponding relation can be obtained in advance through a plurality of times of test tests or through a specific relational expression.
Specifically, the processor 20 calculates the zoom factor F1 according to the formula F1 ═ P1/P2 ═ (D1 × Y1) × ppi S1/D × Y2 × ppi S1, where D1 is the detection distance, Y1 is the correction degree, and D is the distance between the optical lens and the display screen 11 when the optical lens is at the initial position. Ppi is picture pixel density, and S1 is the physical movement distance of the input device 200 (shown in fig. 4) controlling the pointer movement. Y2 is normal diopter, typically 1.
Therefore, the scaling factor F1 ═ P1/P2 ═ D1 × Y1 × ppi S1/D × Y2 × ppi S1, which can be simplified to F1 ═ D1 × Y1)/D.
Wherein, P1 (D1Y 1) ppi S1 is the moving distance of the pointer on the display screen when the input device 200 moves the distance S1 when the distance between the optical lens 12 and the display screen 11 is D1. P2 is d Y2 ppi S1, which is the moving distance of the pointer on the display screen when the input device 200 moves the distance S1 when the distance between the optical lens 12 and the display screen 11 is the initial distance d.
Wherein, P1/P2 is the ratio of the moving distance of the pointer in the zoomed display screen to the moving distance in the normal/initial display screen when the input device 200 moves the same distance, which is equivalent to the zoom multiple of the display screen. The larger the amplification factor is, the lower the sensitivity factor needs to be adjusted, so as to avoid the problem that the moving distance is amplified too much to cause the sensitivity to be too high.
Therefore, the scaling factor is inversely proportional to the sensitivity. The processor 20 determines the inverse of the scaling factor as the target pointer sensitivity factor. Thus, the target pointer sensitivity factor is D/(D1Y 1).
As shown in fig. 1, the sensor unit 30 includes a signal generating unit 31 and a signal receiving unit 32. One of the signal generating unit 31 and the signal receiving unit 32 is disposed on the optical lens 12, the other of the signal generating unit 31 and the signal receiving unit 32 is disposed on the display screen 11, the signal generating unit 31 is configured to generate a specific signal, and the signal receiving unit 32 is configured to receive the specific signal and determine a distance between the optical lens 12 and the display screen 11 according to the received specific signal.
For example, in some embodiments, the signal generating unit 31 is an infrared transmitter for transmitting an infrared signal, and the signal receiving unit 32 is an infrared receiver for receiving the infrared signal and determining the distance between the optical lens 12 and the display screen 11 according to the time interval between the receiving of the infrared signal and the transmission of the infrared signal by the infrared transmitter and the speed of the infrared signal.
For another example, in some embodiments, the signal generating unit 31 is a magnet, and the signal receiving unit 32 is a magnetic force receiving sensor, configured to detect or receive a magnetic force generated by the magnet, and determine a distance between the optical lens 12 and the display screen 11 according to a strength of the received magnetic force.
As shown in fig. 1, the display device 10 further includes a driving unit 13, where the driving unit 13 is connected to the optical lens 12 and is configured to drive the optical lens 12 to move along the output path of the display screen in response to a user operation so as to increase or decrease the distance between the optical lens 12 and the display screen 11.
The optical lens 12 is mounted on an axis (not shown) parallel to the user's sight line and/or parallel to the output path of the display screen and is driven by the driving unit 13 to move along the axis so as to move closer to or away from the user's eye/exit pupil position C1 (i.e., move away from or close to the display screen 11) for focusing, and exists as a corrective lens having a corresponding correction power.
In the present embodiment, the optical lens 12 is a magnifying lens, such as a convex lens, and the magnification of the display screen on the display screen 11 entering the human eye when the optical lens 12 moves in response to the driving of the driving unit 13 is changed to change the correction power.
Referring to fig. 3, when the optical lens 12 is driven to move to enlarge the display image, the image that the display screen 11 outputs the display image and enters the human eye after passing through the optical lens 12 is an enlarged virtual image M1, and the effect seen by the human eye is an enlarged display effect.
Please refer to fig. 4, which is a schematic diagram of the overall structure of the head-mounted display apparatus 100. The head-mounted display apparatus 100 is also connected with an input device 200. The input device 200 is used for controlling input control such as movement of a pointer. The input device 200 may be a touch pad, a mouse, or a touch screen of a mobile phone, a tablet computer, or the like.
The processor 20 adjusts a pointer sensitivity factor according to the detected distance detected by the sensor unit, so as to adjust the sensitivity of the pointer movement, including: when the input apparatus 200 controls the pointer to move, the physical movement distance of the input apparatus 200 is multiplied by the pointer sensitivity factor to obtain the movement distance of the pointer on the display screen, and the control target pointer moves a corresponding distance on the display screen, and the sensitivity of the pointer movement is adjusted accordingly. Thus, the adjustment of the sensitivity is achieved by adjusting the sensitivity factor.
When the input device 200 is a mouse, the physical movement distance is a movement distance of the input device 200 itself, and when the input device 200 is a touch pad or a touch screen, the physical movement distance may be a movement distance of a finger, a touch pen, or the like touching the input device 200.
As shown in fig. 4, the head-mounted display device 100 further includes an adjustment button 40, and the adjustment button 40 is located outside the head-mounted display device 100 and can be operated by a user. The driving unit 13 drives the optical lens 12 to move in response to the user's operation of the adjustment button 40. For example, the adjusting button 40 may be a knob, and the adjusting button 40 may be directly connected to the driving unit 13, so that the adjusting button 40 moves the driving unit 13 in response to the rotation of the user, and the driving unit 13 drives the optical lens 12 to move.
In some embodiments, the adjustment button 40 generates an adjustment signal in response to a user operation, and the processor 20 is further connected to the adjustment button 40 and the driving unit 13, and controls the driving unit 13 to drive the optical lens 12 to move correspondingly after receiving the adjustment signal.
Therefore, in the invention, when the user wears the head-mounted display device 100 and adjusts the position of the optical lens 12 according to the degree of eyes of the user so as to zoom the display picture, the sensitivity of the pointer is correspondingly adjusted, so that the degree of the user can be adjusted to be matched with the normal sensitivity no matter how much the display picture is zoomed, and the requirements of different user groups are met.
As shown in fig. 4, the head-mounted display device 100 further includes an earphone device 60, where the earphone device 60 includes an earphone band 61 and two earphone earphones 62, and the earphone band 62 is used for electrically connecting the two earphone earphones. Wherein the adjustment button 40 may be disposed on the headphone 62.
The processor 20 may be a microcontroller, a microprocessor, a single chip, a digital signal processor, or the like.

Wherein, the step S503 specifically includes: and adjusting a pointer sensitivity factor (factor) at least according to the detection distance detected by the sensor unit 30 to realize the adjustment of the sensitivity of the pointer movement. Wherein the moving distance of the pointer is equal to the physical moving distance of the input device 200 multiplied by the pointer sensitivity factor, and when the pointer sensitivity factor is changed, the moving sensitivity of the pointer is also changed accordingly, so that the adjustment of the pointer moving sensitivity can be realized by adjusting the pointer sensitivity factor.
Wherein, in some embodiments, the input control method further comprises the steps of: the optical lens 12 is controlled to move along the direction of the light outgoing path of the display screen displayed on the display screen 11 in response to a user operation. The steps can be executed before the step S501, and when the position of the optical lens 12 moves, the detection distance D1 detected by the sensor unit 30 will also change accordingly.
