Touch Operation Surface with Downward Movement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch sensing type input apparatuses require multiple operations for scrolling and page turning, which are inconvenient and often necessitate additional mechanical switches, increasing the size of the operation apparatus.
Innovation Solution
An operation apparatus with a touch operation surface that moves in up and down directions, featuring a sensor and an outer frame element or dead zone that distinguishes between finger touches on the surface and the frame or dead zone, allowing for simplified scrolling and page turning operations without additional mechanical switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If scroll switches (mechanical switches) are provided separately in addition to the touch panel, then scroll operations become easier, but the operation apparatus upsizes
Solution Approach 1:
The touch panel is designed to perform multiple functions: it serves as both the display interface and the scrolling mechanism. By detecting touch positions and movements on the touch panel itself, the system eliminates the need for separate mechanical scroll switches, thereby maintaining ease of operation while reducing apparatus size.
Solution Approach 2:
The patent replaces mechanical scroll switches with a touch-based sensing system. The touch panel uses electrical or capacitive sensors to detect finger touches and movements, substituting the mechanical switching mechanism with an electronic sensing and processing system that achieves the same scrolling function without additional mechanical components.
2Measurement precision
If multiple operations are required for scrolling (selection operation followed by enter operation), then the touch panel can identify precise selection targets, but the operation process becomes more complex and less convenient
Solution Approach 1:
The system performs preliminary detection of touch position and movement direction on the touch panel. By analyzing the touch coordinates and movement trajectory in advance, the system can determine the intended scroll direction and target area, allowing it to execute scrolling operations automatically without requiring a separate enter operation, thus maintaining precision while simplifying the operation process.
Solution Approach 2:
The system provides visual feedback on the display showing the current touch position, selection target, and scroll direction. This feedback mechanism allows users to confirm their selection intent before the scrolling action is executed, ensuring precise target identification while reducing the number of required operations through intuitive visual confirmation.

AI summary
An operation apparatus includes a touch operation surface configured to move in up and down directions, with a sensor for outputting a signal representing a touch of a finger thereon, and with an outer frame element or a dead zone; a downward movement detection part that outputs a signal representing a movement of the touch operation surface in the down direction; and a control device that executes, when the movement of the touch operation surface in the down direction is detected while the touch of the finger on the touch operation surface is not detected, at least one of scrolling lists in an image area or the image area itself displayed in a display that is located remotely with respect to the touch operation surface, changing the image area displayed on the display to another image area, and successively moving a cursor in the image area displayed on the display.
