Combined Touch Input and Offset Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-sized screens on user devices limit interactive input capabilities, requiring repeated actions for tasks like scrolling, zooming, and obscuring the screen with touch inputs.
Innovation Solution
Concurrently capturing touch input data and non-touch gesture data using sensors like ultrasound, cameras, or depth sensors to create combined input commands without obstructing the screen view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch interactions are used on small-sized screens, then input capabilities are limited and repeated actions are required, but screen space is obstructed and visibility is reduced
Solution Approach 1:
The patent extends interaction beyond the two-dimensional screen surface by detecting gestures in three-dimensional space. Sensors capture hand gestures performed off-screen, allowing users to control the interface without physically touching the display, thus preserving screen visibility while enhancing input capabilities through spatial dimensionality.
Solution Approach 2:
The patent introduces sensors (ultrasound, camera, depth sensors) as intermediary devices that detect gestures in the air. These sensors act as mediators between the user's hand movements and the system response, enabling control without direct screen contact and maintaining full screen visibility throughout the interaction.
2Measurement precision
If multiple touch inputs are used to perform tasks, then input precision is improved, but screen obstruction increases and user comfort decreases
Solution Approach 1:
The patent replaces mechanical touch-based input with non-contact gesture recognition. By using sensors to detect hand gestures in the air, the system eliminates the need for repeated physical touches on the screen, improving user comfort while maintaining input precision through sophisticated gesture parsing and recognition algorithms.
3Adaptability or versatility
If sensors are added to detect non-touch gestures, then input versatility is enhanced, but device complexity increases
Solution Approach 1:
The patent implements sensors with multi-functionality, where the same sensor system (ultrasound, camera, depth sensors) detects both touch inputs and non-touch gestures. This universal approach allows a single sensor system to handle multiple input modalities, enhancing versatility while minimizing the complexity increase that would result from adding separate dedicated systems for each input type.
Data Source
AI summary
Methods and systems according to one or more embodiments are provided for combining touch inputs and offset non-touch gestures. In an embodiment, a method includes concurrently capturing touch input data on a screen of a user device and non-touch gesture input data, the non-touch gesture input data being indicative of a gesture performed in an area offset from the screen of the user device to inhibit obstruction of a user's view of the screen. The method also includes determining an input command based at least in part on a combination of the concurrently captured touch input data and the non-touch gesture input data. In addition, the method further includes affecting an operation of the user device based on the determined input command.
