Non-Contact Display Selection Using Memory Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses with touch panels require direct user interaction for screen operations, limiting convenience and efficiency in scenarios where physical contact is not feasible.
Innovation Solution
Implementing a non-contact mode of operation where a memory device, such as an IC card or smartphone, is used in proximity to a reader to perform screen operations by detecting its presence and absence, allowing selection of display elements without physical touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct user interaction with touch panel is required for screen operations, then operation reliability is ensured, but ease of operation deteriorates in scenarios where physical contact is not feasible
Solution Approach 1:
The patent introduces a memory device as an intermediary between the user and the information processing apparatus. The memory device stores operation information and transmits it to the apparatus via a reader, enabling non-contact operation. This mediator allows users to perform screen operations without physically touching the touch panel, resolving the contradiction between ease of operation and device complexity by adding a simple external component rather than complicating the apparatus itself
2Ease of operation
If non-contact operation mode is implemented using memory device, then ease of operation improves, but device complexity increases due to additional reader and detection mechanisms
Solution Approach 1:
The reader component is designed with multi-functionality, serving both as an authentication device for reading memory devices and as an operation input device for detecting presence/absence states. By making the reader universal, the patent avoids adding separate dedicated components for non-contact operation, thereby reducing the increase in device complexity while maintaining improved ease of operation
3Productivity
If presence and absence detection of memory device is used for screen navigation, then productivity improves through faster operations, but measurement precision requirements increase for accurate detection
Solution Approach 1:
The patent extracts the operation information from the physical touch interaction and stores it in the memory device. The reader only needs to detect the presence or absence of the memory device and read its identification, rather than precisely measuring touch position or force. This extraction of the detection requirement from precise spatial measurement to simple presence detection reduces measurement precision requirements while maintaining high productivity through fast operation execution

Data Source
AI summary
An information processing apparatus includes a processor configured to: detect, via a reader, a memory when placed in close proximity to the reader or when spaced apart from the reader after being in close proximity to the reader; and at each timing when the memory is detected, perform display control such that a selection element, out of multiple selection elements displayed on a display, is in a selected display state.
