Display Controller for Near-Field Communication Contact Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of near-field wireless communication in user interfaces for image forming apparatuses can lead to unintended operations when a wireless communication device comes into contact with the display, causing incorrect activation of functions due to simultaneous detection of contact and communication.
Innovation Solution
A detection apparatus comprising a display, a communication unit, and a controller that uses a light detecting unit to determine the position and intensity of a detection target, allowing the controller to differentiate between intended user operations and communication-induced contacts, and cancels operations based on predetermined thresholds to prevent incorrect activations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If near-field wireless communication is integrated in the user interface, then communication functionality is improved, but unintended operations occur when a wireless communication device contacts the display
Solution Approach 1:
The control unit determines whether a detected contact operation should be executed before the wireless communication device completes contact with the display. By performing preliminary determination of operation intent, the system can prevent unintended operations from occurring, thus resolving the contradiction between adding communication functionality and maintaining operation accuracy.
2Ease of operation
If contact detection is enabled on the display, then user interaction capability is improved, but communication-induced contacts cause incorrect activations
Solution Approach 1:
The control unit uses feedback from both the contact detection unit and the wireless communication unit to determine whether to execute an operation. By综合分析 contact timing, position, and communication state, the system can distinguish between intentional user contacts and accidental contacts caused by wireless devices, thus preventing incorrect activations while maintaining ease of operation.
3Speed
If the system responds to all contact detections, then responsiveness is improved, but false operations are triggered by communication devices
Solution Approach 1:
The control unit performs preliminary judgment about operation validity before executing any contact-based operation. By determining whether the contact was intentional based on timing and context information, the system maintains fast responsiveness to valid operations while filtering out false triggers from communication devices.

AI summary
A detection apparatus includes a display, a communication unit, and a controller. The display displays an image and receives an operation corresponding to the image in such a manner that a user comes into contact with the image. The communication unit communicates with a wireless communication apparatus performing near-field wireless communication. Before or after the communication unit senses the wireless communication apparatus, when contact with the display is detected, the controller exercises control in such a manner that an operation of the detection apparatus based on the detection result is canceled.
