Adaptive Display Area Control via Back Touch Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in viewing information on an information processing device when holding it with one hand, as displayed information can be obscured by their hand, and existing solutions do not effectively adapt the display area based on hand orientation.
Innovation Solution
The device incorporates a front touch sensor overlapped on the display and a back touch sensor to detect hand orientation, identifying prohibited areas on the display and positioning information outside these areas for optimal visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If information is displayed in the lower right area of the display when the user holds the device with the left hand, then the display area is utilized, but the information is hidden by the user's hand and becomes difficult to see
Solution Approach 1:
The display area dynamically changes based on detected hand orientation. The control section identifies prohibited areas and adjusts where information is displayed according to the detected position by the back touch sensor, making the display adaptive rather than static.
Solution Approach 2:
The back touch sensor detects the user's hand position and provides feedback to the control section. This feedback loop allows the system to continuously monitor hand orientation and adjust the display area accordingly, ensuring information remains visible.
2Device complexity
If the display area is fixed regardless of hand orientation, then the device structure is simple, but the information may be obscured by the user's hand
Solution Approach 1:
The back touch sensor serves multiple functions: it detects hand orientation and enables dynamic adjustment of the display area. This multi-functionality allows the system to maintain simplicity while improving ease of operation through adaptive display control.
3Loss of information
If a back touch sensor is added to detect hand orientation and adjust display area, then visibility is improved, but the device complexity increases
Solution Approach 1:
The back touch sensor acts as an intermediary that detects hand orientation without requiring direct contact with the front display. This indirect detection method provides necessary information for display adjustment while maintaining a simple overall structure.

AI summary
The present invention is to allow change of the area in which information as a display target is not displayed in a display according to a detected position by a touch sensor disposed opposed to a touch sensor that is so disposed as to be overlapped on the display. An information processing device (1) includes a touch panel (12) that is so configured as to include a display and a front touch sensor that is so disposed as to be overlapped on the display and detects the position of an object on a detection surface, a back touch sensor (18) that is disposed opposed to the front touch sensor and detects the position of an object on a detection surface, and a control section. The control section identifies, as a prohibited area, one of two areas that each occupy part of the display and are disposed on the left and right sides based on at least one detected position by the back touch sensor (18), and causes information as a display target to be displayed in an area outside the prohibited area in the display.
