Motion Input Device with Visual Feedback for Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices fail to provide users with intuitive feedback on how their motions are recognized, leading to unintended operations due to misinterpretation of gestures or poses.
Innovation Solution
An input device with a motion detector and display unit that synchronizes graphical user interface (GUI) changes with detected user motions, providing visual feedback on recognized actions to prevent unintended operations by displaying motion positions and necessary gestures for intended operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion detection is implemented without visual feedback, then device operation capability is provided, but user understanding of gesture recognition is lost leading to unintended operations
Solution Approach 1:
The patent implements a feedback mechanism by displaying a graphical representation of the user's detected pose or motion on the display unit. This visual feedback allows users to confirm whether their gesture was correctly recognized before the operation is executed, preventing unintended operations while maintaining ease of use.
Solution Approach 2:
The patent introduces an intermediary visual representation (graphical display of detected pose/motion) that mediates between the user's physical gesture and the system's interpretation. This intermediary provides users with information about how their motion is being recognized without requiring direct system feedback communication.
2Adaptability or versatility
If gesture recognition system is added to provide motion input, then operation capability is enhanced, but complexity of the device increases
Solution Approach 1:
The patent makes the display unit serve multiple functions: it displays both the graphical user interface for operation and the visual feedback of detected poses/motions. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while enhancing adaptability.
Solution Approach 2:
The patent merges the gesture recognition system with the existing display unit, combining the functions of motion detection and visual output into an integrated system. This merging approach enhances motion input capability while avoiding the complexity increase that would result from separate dedicated feedback hardware.
3Reliability
If visual feedback of detected motion is displayed, then user understanding of gesture recognition is improved, but processing time increases
Solution Approach 1:
The patent performs motion detection and generates the visual feedback representation in advance of the actual operation execution. By preparing the feedback display during the detection phase rather than after recognition, the system minimizes additional processing time while improving reliability through timely visual confirmation.
Solution Approach 2:
The patent implements continuous motion detection and continuous update of the visual feedback display, creating a seamless flow of information. This continuous action approach ensures that users receive timely feedback without noticeable delays, maintaining fast response times while improving gesture recognition reliability.

AI summary
An input device includes an input unit for inputting a predetermined motion image signal, a motion detector for detecting a motion on the basis of the motion image signal inputted into the input unit, a video signal processor for outputting a predetermined video signal, and a controller. The controller controls the video signal processor so that, when a motion detector detects a first motion, the video signal processor outputs a video signal to explain a predetermined second motion to be next detected by the motion detector after the detection of the first motion to a user.
