Techniques for a visual disability detection system that employs virtual reality to assess visual performance of a patient based on activities of daily living are described. The virtual reality platform can integrate the testing of different components of visual function based on activities of daily living to provide a direct and clinically relevant measure of the impact of any visual disability on a patient's daily life. By simulating daily tasks for evaluation of visual disability, clinicians can better understand from a patient's perspective how visual impairment affects their daily tasks and quality of life.

A feeding bottle includes a body, a temperature sensing and measuring plate on a lateral wall portion of the body, and a plate-shaped warning device covered by the temperature sensing and measuring plate; the temperature sensing and measuring plate can change colors with temperature to indicate the temperature for the users such as the parents, nursing persons, and diners; the warning device can give a certain kind of sound effect according to the temperature so that the parents/nursing persons can easily make sure that the food contents of the feeding bottle isn't too hot before they feed little children/persons with disabilities; little children, the elderly, and persons with visual disabilities also can be directly warned by the warning sound effects given by the warning device if the temperature is too high.

The invention relates to a liquid crystal display device critical point disability test method, comprising the steps of: inputting a check voltage different from a normal working range into a liquid crystal display device; collecting the display picture output by the liquid crystal display device, and judging the uniformity sharpening degree of the check image to obtain the liquid crystal display device critical point disability result. The invention inputs a check voltage different from a normal working range, to represent the electric disability and visual disability of difficult discovery, thereby effectively detecting the critical point disability of a liquid crystal display device.

The method is suitable for the technical field of password auxiliary input. The invention provides a password input method and a terminal device. The terminal device is provided with an auxiliary device matched with a virtual keyboard. The auxiliary device comprises: a first support provided with a touch mark, and a second support provided with a touch mark. The password input method comprises thefollowing steps of: after a person with visual impairment is monitored to find a column where a target key is located by touching a touch mark on the first bracket, the first preset gesture sliding along the column where the target key is located; or, after the visual impairment person finds the row where the target key is located by touching the touch mark on the second support, after a first preset gesture sliding along a row where a target is located is detected, sending out voice information, and after a second preset gesture is detected, characters at the contact position of the first preset gesture can be input, so that a person with visual impairment is assisted in inputting a password through a touch screen.

The invention relates to assessing the level of visual contrast between foreground and background in visually presented information, and more particularly, to a method and apparatus for determining whether a given set of foreground and background colors creates sufficient visual contrast to ensure legibility for the general population, as well as for individuals with visual disabilities, including color blindness/deficiency.

In 2019, the World Health Organization stated that globally, approximately 2.2 billion people live with some form of vision impairment. Visual impairment limits the ability to perform everyday tasks and adversely affects the ability to interact with the surrounding world, thus discouraging individuals navigating unpredictable and unknown environments. The present invention is a method and a system to define and develop a smart navigation intelligent cane (i-Cane) that enables a visually impaired person to navigate his or her environment. The method and the system detects objects along the path of the visually impaired person, measures the distance of the objects from the person, identifies the objects, uses speech to alert the person of the approaching objects, the type of objects obstructing the path, and the distance between the objects and the person.
