Input Device Tactile Feedback for Hidden Data Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of input devices, such as mobile phone terminals, face difficulties in recognizing the existence of data set to a non-display setting, leading to re-registration of hidden data and mistaken searches, especially as the number of secret settings increases.
Innovation Solution
An input device equipped with a touch sensor, display unit, tactile sensation providing unit, and control unit that provides a tactile sensation when data set to a non-display setting is detected, allowing users to easily recognize its presence through contact and pressure thresholds, and cancels the non-display setting upon specific touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-display setting is applied to hide data, then data security is improved, but user awareness of hidden data deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the display unit provides visual feedback (displaying 'non-display setting data exists') and the tactile sensation providing unit provides haptic feedback when the user presses on a display item that has hidden data. This feedback system informs users about the existence of non-display setting data without compromising its hidden nature, resolving the contradiction between data security and user awareness.
Solution Approach 2:
The patent introduces an intermediary mechanism through the tactile sensation providing unit that acts as a mediator between the user and the hidden data. When the user presses on a display item, the intermediary (tactile sensation unit) provides feedback about the existence of non-display setting data associated with that item, allowing users to become aware of hidden data through a intermediate haptic channel rather than direct visual exposure.
2Reliability
If non-display setting is set for multiple data items, then data protection is improved, but operation complexity deteriorates
Solution Approach 1:
The patent applies local quality by providing differentiated tactile feedback based on the specific display item being pressed. Each display item that has non-display setting data associated with it provides a specific tactile sensation when pressed, allowing users to identify which specific items have hidden data. This localized approach makes it easier to manage multiple protected data items individually rather than dealing with them as a uniform complex system.
3Reliability
If user must cancel non-display setting to view data, then data security is maintained, but time consumption increases
Solution Approach 1:
The patent implements preliminary action by providing advance information about the existence of non-display setting data through visual feedback (displaying 'non-display setting data exists') and tactile feedback before the user needs to access the data. This allows users to plan their actions in advance, understand what data is hidden and where it is located, and prepare for the cancellation process, thereby reducing overall time consumption while maintaining security until explicit cancellation occurs.

AI summary
To support a non-display setting for each piece of data corresponding to a display item, and to easily allow the user to recognize the existence of data set to a secret setting, the input device (101) according to the present invention includes a touch sensor (104) that detects contact, a display unit (103), a tactile sensation providing unit (107) that provides a tactile sensation to a contacting object in contact with the touch sensor (104), and a control unit (108) that controls the tactile sensation providing unit (107) to provide the tactile sensation to the contacting object in contact with the touch sensor (104) when, for a display item being displayed on the display unit (103), data set to the non-display setting exists in correspondence with the display item.
