Real-Time Gesture Feedback for Input Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of gesture-based user interfaces face challenges in understanding the required inputs to interact with electronic devices effectively, leading to accidental activations and precision issues with selecting icons or buttons, especially for those unfamiliar with the interfaces or unable to concentrate on the screen.
Innovation Solution
A method and device that detect user input via an input interface, generating display data with a display object representing the action to be performed, allowing users to determine the outcome of their input in real-time, with the display object appearing at a different rate than the input is detected, providing additional information and guiding the user on input completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture-based user interfaces are used to enable diverse input types, then the device becomes more versatile and easier to control, but users become confused about required inputs leading to accidental activations
Solution Approach 1:
The system provides real-time visual feedback by displaying a representation of the upcoming action during the input sequence. This feedback mechanism allows users to see what action will be triggered before completing the gesture, enabling them to prevent accidental activations by stopping the input sequence if the displayed action is not desired.
2Measurement precision
If precise input commands are required for selecting icons or buttons, then control precision is improved, but users who are unfamiliar or unable to concentrate on the screen cannot execute the required motions with necessary precision
Solution Approach 1:
The system displays the representation of the action to be performed during the input sequence, allowing users to plan and adjust their input motion in real-time. This preliminary visualization of the outcome helps users who are unfamiliar with the interface or unable to concentrate, as they can see what their input will achieve before completing the precise motion required.
Solution Approach 2:
By providing real-time visual feedback during the input sequence showing the upcoming action, users can adjust their input precision dynamically. If the displayed action indicates they are targeting the wrong icon or button, they can modify their gesture mid-execution, making precise selection easier for users who struggle with motor precision or concentration.
Data Source
AI summary
A method for generating display data comprises detecting user input via an input interface. A processor is in communication with the input interface to generate display data comprising a display object for display by a display device. The display object is representative of an action that will subsequently be performed by the processor on continuation of the user input. The display data on the display device is output whilst the user input is being detected. Alternatively, the display object is caused to appear on the display device over time as the user input is being performed, wherein the rate at which the display object appears is different to the rate of performance of the user input. A device and executable computer program for performing the steps of the method is also provided.
