Indirect Touch Input Region for Touch Screen Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch screen displays require users to touch selectable elements directly, which can obscure the elements and surrounding content, making it burdensome and interrupting the user's experience, especially on larger displays where reaching the selection location is difficult.
Innovation Solution
The solution involves providing an input region proximate to the main display area where touch inputs are received without overlapping with the main display, allowing for the determination of an extrapolated touch input based on the location in the input region, enabling selection of elements without obscuring them, and optionally using visual representations like rays to indicate the touch input location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users touch selectable elements directly on the touch screen display, then selection accuracy is improved, but the selectable elements and surrounding content are obscured
Solution Approach 1:
The patent introduces an intermediary input region adjacent to the main display area where touch inputs are received indirectly. This input region acts as a mediator between the user's touch and the selectable elements on the display, allowing selection without direct contact that would cause obscuration. The system maps touches in the input region to corresponding locations on the display through extrapolation.
2Manufacturing precision
If users touch selectable elements directly on the touch screen display, then selection precision is improved, but user experience is burdened and content consumption is impeded
Solution Approach 1:
The patent extends the input space by adding an adjacent input region that is spatially separated from the main display area. This dimensional extension allows users to interact with elements on the display without physically touching them, creating a new interaction dimension that improves ease of operation while maintaining selection precision through coordinate extrapolation.
3Area of stationary object
If the display size is increased, then content display area is improved, but reaching selection locations becomes difficult
Solution Approach 1:
For large displays where direct touching is difficult, the patent provides an adjacent input region that serves as an intermediary access point. Users can touch this nearby region instead of reaching across the large display, and the system maps these touches to the appropriate selectable elements through extrapolation, making large displays more accessible.

AI summary
Mechanisms are described for receiving touch inputs on a touch screen display in a way that does not obscure the images and content presented on the display. Content, including selectable elements, is displayed in a main portion of a display, where as an input region that does not overlap with the main portion is provided on the display for receiving touch input selecting particular selectable elements. An extrapolated touch input in the main portion of the display is determined based on the location of the touch input in the input region, such that selection of a particular selectable element may be accomplished when the location of the extrapolated touch input coincides with the location of the selectable element.
