Touchscreen Grid Layout for Accurate Finger Braille Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile information terminals, such as smartphones, are challenging for visually and hearing impaired individuals to use due to difficulties in recognizing input/output sections on the display screen, leading to tapping errors and limited functionality when combined with external devices like finger braille devices.
Innovation Solution
The display screen is divided into 8 sections by partitions with orthogonality, with fixed positions for input/output sections, aligning with finger braille operations and incorporating external devices for bidirectional communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display screen is divided into multiple sections with flexible positioning, then the information display capability is improved, but the ease of operation for visually impaired users deteriorates due to difficulty in recognizing input/output section positions
Solution Approach 1:
The display screen is divided into 8 equal sections by vertical and horizontal partition lines, creating a grid structure. Each section has a fixed position that corresponds to finger braille operations, allowing visually impaired users to accurately locate input/output sections through tactile feedback from the partition lines without confusion from flexible positioning.
2Adaptability or versatility
If a finger braille device is worn on the finger for bidirectional communication, then the communication capability is improved, but the ease of operation deteriorates because other tactile functions of the finger pads cannot be sufficiently used
Solution Approach 1:
The finger braille device is integrated with the mobile information terminal, combining the communication device with the smartphone into a unified system. This allows bidirectional communication while preserving all tactile functions of the finger pads, as the device works together with the terminal rather than replacing natural finger interaction.
3Reliability
If a dedicated device is used for receiving and transmitting finger braille information, then the communication reliability is improved, but the adaptability deteriorates because the device lacks portability and cannot be constantly utilized in daily activities
Solution Approach 1:
The mobile information terminal serves multiple functions: it acts as a smartphone for general use, a communication device for finger braille operations, and a display device with tactile feedback. This multi-functional design allows the same device to be used constantly in daily activities both as a regular smartphone and as a specialized communication tool for visually impaired users.

AI summary
Provided is a mobile information terminal with a display screen superior in responsiveness that causes few tapping errors for a visually impaired person, and that is capable of operating together with an external device. In the mobile information terminal, input/output sections are formed by dividing an entire display screen into 8 sections with partitions with orthogonality, and each of the input/output sections is positioned within the entire display screen relative it. Representatively, in the mobile information terminal, the input/output sections formed by dividing an entire display screen into 8 sections by partitions with orthogonality has a total number of 8 sections being 1 finger number for each hand having an operation function added to 1 to 6 finger braille numbers assigned to three fingers of each hand of a visually and hearing impaired person, and each of the input/output sections is positioned within the entire display screen relative it.
