Touch Sensor Input Area Segmentation for Versatile Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input apparatuses for display systems, such as remote controllers, are limited in the types of user inputs they can receive, primarily allowing only cursor movement and pointing commands, which restricts user interaction.
Innovation Solution
An input apparatus with a touch sensor that divides its input area into multiple regions, allowing for specific coordinate value changes (X and Y) to be sensed and translated into commands for navigating web pages or controlling setting menus, enabling more comprehensive user input through touch inputs like dragging across the sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the input area is divided into multiple setting areas with specific coordinate sensing, then the versatility of user input is improved, but the device complexity increases
Solution Approach 1:
The input area of the touch sensor is divided into multiple setting areas (first area, second area, third area, fourth area located at top, bottom, left and right sides). Each setting area corresponds to specific coordinate value changes (X or Y), enabling diverse input functions through spatial segmentation. This resolves the contradiction by providing versatile input capabilities through area division rather than complex hardware.
Solution Approach 2:
Different setting areas are assigned different functions based on their location. For example, top and bottom areas control horizontal scrolling (X coordinate), while left and right areas control vertical scrolling (Y coordinate). This local differentiation enables versatile input without requiring complex processing logic throughout the entire device.
2Ease of operation
If coordinate-based commands are used for navigation and control, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The input area is segmented into distinct setting areas that map to specific coordinate changes. This segmentation provides clear operational zones for users (improving ease of operation) while the touch sensor technology inherently handles the precision measurement of touch locations, transferring manufacturing precision requirements to the sensor component rather than the overall device assembly.
Solution Approach 2:
The patent replaces traditional mechanical input mechanisms with a touch sensor-based coordinate system. This substitution improves ease of operation by enabling intuitive touch interactions, while the precision requirements are managed through electronic sensing rather than mechanical tolerances, reducing overall manufacturing complexity.

AI summary
An input apparatus, a display apparatus and a control method thereof are provided. The input apparatus includes a communication transceiver which is configured to communicate with the display apparatus; a touch sensor which is configured to receive a touch input; and a controller which is configured to divide an input area of the touch sensor into a plurality of areas, and in response to the touch sensor receiving a touch input that ends in at least one setting area of the plurality of areas, sense a change in one of coordinate values X and Y with respect to the received touch input, and control the communication transceiver to transmit a command to the display apparatus corresponding to the sensed change.
