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]As shown in FIGS. 1-2 , 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 source fo...

Abstract

A touch-based simulated false-vision positioning system in the technical field of visual prostheses comprises a helmet display, an auxiliary head positioning device, a touch screen, a computer, a touch navigation device and a touch panel. Firstly, the helmet display which is used as a stimulating source provides simulated false vision stimulation; with the auxiliary head fixing device, the head of a user is fixed opposite to where the touch screen is fixed; simulated false-vision generating software with an appropriate stimulating mode is selected and facilitates the computer to produce simulated false vision; after judging the positions of simulated false visions in the helmet display, the user points out the localization on the touch screen with the help of the touch navigation device or the touch panel; after feedback data is processed with corresponding software, analysis and evaluation on information such as localization accuracy, dispersion, etc. of simulated false visions sensed by touch can be obtained.

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...
