Bistable Display Proximity Detection for Handwriting Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bistable displays used in information processing apparatuses face responsiveness issues during handwriting input due to competition between redisplaying and drawing processing, especially when increasing bit depth, leading to delayed response times.
Innovation Solution
The apparatus detects the proximity of an operating object to a detection plane and switches display modes based on the detected distance, executing drawing processing when close and redisplaying processing when the object is beyond a threshold distance, thereby avoiding competition between the two processes.

Engineering Contradiction Analysis
1Manufacturing precision
If the bit depth is increased to display images with higher quality, then the image display quality is improved, but the display response time becomes longer
Solution Approach 1:
The display mode is dynamically changed based on the detected state of the operating object. When the operating object is in proximity to or contacting the detection plane, the system switches to a first display mode with shorter response time. When the operating object is away from the detection plane, the system switches to a second display mode with higher image quality. This dynamic adaptation resolves the contradiction by adjusting display quality and response time according to operational context.
2Speed
If the display mode is temporarily changed to improve handwriting input responsiveness, then the handwriting input responsiveness is improved, but processing competition between redisplaying and drawing processing occurs
Solution Approach 1:
The system performs preliminary switching to the first display mode when the operating object approaches or contacts the detection plane, before handwriting input occurs. This preparatory action ensures that the display is already optimized for fast response when the user begins writing, eliminating the need for competitive processing during actual handwriting input. The switch to the second display mode is performed preliminarily when the object moves away, preparing for potential subsequent operations.

AI summary
[Object] To propose an information processing apparatus, an information processing method, and a program, which are capable of preventing deterioration in responsiveness of handwriting input.[Solution] Provided is an information processing apparatus including: an acquisition unit configured to acquire a detection result from a detector that detects proximity of an operating object to an operation subject; and a display controller configured to, in a case where the display controller recognizes that a distance between the operation subject and the operating object, which are spaced apart from each other, exceeds a threshold on the basis of the detection result, cause a display to display an image in a display mode different from a display mode used in a case where the distance is less than or equal to the threshold.
