Problems solved by technology

Its shortcoming is: since one hand must be used as a reference point, when indicating some positions on the hemisphere, the hand as the reference point must be bypassed, which constitutes the systematic error of this method

Embodiment Construction

[0027] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following implementations example.

[0028] Such as Figure 1-2As shown, this embodiment includes a head-mounted display HMD1 , a head positioning aid 2 , a touch screen 3 , a computer 4 , a tactile navigation device 5 and a touchpad 6 . The head auxiliary positioning device 2 is fixed on the edge of a platform. After the user puts on the head-mounted display 1, the front of the head-mounted display 1 faces the head auxiliary positioning device 2, and the head auxiliary positioning device 2 is adjusted to fix the position of the user's head. The head-mounted display 1 is connected with the computer 4 as a stimulus so...

Abstract

A tactile-based simulated visual hallucination positioning system in the field of visual prosthesis technology includes a helmet-mounted display, a head auxiliary positioning device, a touch screen, a computer, a tactile navigation device and a touch panel. First, the head-mounted display is used as the stimulus source to provide simulated visual hallucination stimulation, the user's head is fixed at a fixed position relative to the touch screen by the head auxiliary positioning device, and the simulated visual hallucination generating software with the appropriate stimulation mode is selected, and the simulated visual hallucination is generated by the computer , after the user judges the position of the simulated visual illusion in the head-mounted display, with the assistance of a tactile navigation device or a touch pad, the user indicates the location on the touch screen, and after the corresponding software processes the feedback data, the simulated visual illusion using tactile perception can be obtained Analysis and evaluation of positioning accuracy, dispersion and other information.

Description

technical field [0001] The invention relates to a system in the technical field of visual prosthesis, in particular to a tactile-based simulated visual illusion positioning system. Background technique [0002] The formation of vision requires a complete visual pathway, including the refractive system of the eyeball, the retina, the visual pathway and the occipital lobe of the cerebral cortex. Lesions in any part of the visual pathway can affect vision and lead to blindness in severe cases. Primary retinitis pigmentosa (RP) and age-related macular degeneration (ARMD) are the leading causes of blindness in the elderly. Visual prosthesis technology is to use the characteristics that most blind people often only have a part of the visual pathway with lesions, while the structure and function of the rest of the nervous tissue are still intact, and apply specific artificial electrical stimulation to the intact part of the visual pathway to excite nerve cells. Simulate the effec...
