Terminal Device Tactile Vibration Encoding for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with visual or auditory impairments face challenges in obtaining information efficiently and accurately in environments with dim light or loud noise, as traditional methods like Braille or auditory perception are inefficient in such conditions.
Innovation Solution
A method and apparatus that convert screen output content into vibration codes, using different frequencies to represent characters, allowing terminal devices to generate vibrations that can be sensed tactilely, enabling information access through touch in challenging environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual or auditory perception methods are used to obtain information, then information can be obtained in normal environments, but efficiency and accuracy significantly decrease in special environments with dim light or loud noise
Solution Approach 1:
The patent replaces visual and auditory perception systems with a tactile perception system. The terminal device converts screen content into vibration patterns that can be perceived through touch, substituting the traditional sensory channels (sight and hearing) with a mechanical tactile channel that is not affected by light or noise conditions.
Solution Approach 2:
The patent changes the parameter of information transmission from visual/auditory signals to tactile vibration signals. By encoding characters as vibration frequencies and patterns, the system transforms the physical form of information delivery to one that is independent of environmental lighting and acoustic conditions.
2Measurement precision
If traditional Braille or auditory methods are used for information access, then information can be obtained, but the efficiency and accuracy significantly decrease in challenging environments
Solution Approach 1:
The patent replaces Braille (a mechanical tactile system requiring physical contact with raised dots) and auditory methods with an electronic vibration system. The terminal device generates controlled vibrations through its haptic motor, providing a more convenient and accurate tactile interface that works in environments where Braille would be difficult to read or auditory methods would be ineffective.
3Loss of information
If visual display methods are used, then information can be presented clearly in normal conditions, but information access becomes difficult in dim light environments
Solution Approach 1:
The patent replaces the optical display system with a mechanical vibration system. Instead of presenting information through light on a screen that becomes invisible in dim conditions, the system presents information through tactile vibrations that can be perceived through touch regardless of lighting conditions, eliminating the dependency on illumination intensity.

AI summary
Some aspects of the disclosure provide a method for information processing. The method includes receiving an output content for a screen display of a terminal device. The output content includes at least a first character. The method includes converting the output content to one or more vibration codes, the first character in the output content is converted into a first vibration code of the one or more vibration codes. The method further includes generating, according to the one or more vibration codes and a set of preset vibration parameters, a device vibration instruction corresponding to the output content, and controlling, according to the device vibration instruction, the terminal device to generate at least a first vibration with a first vibration frequency and a second vibration with a second vibration frequency that is different from the first vibration frequency. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
