Movable Touch Block Object for Unintentional Hit Rejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch input-based devices often misidentify unintentional touches, such as a resting palm, as intentional input, and require inconvenient arm movements to access edge features, especially since keyboard shortcuts are not easily accessible.
Innovation Solution
A touch block object is displayed on the screen to block unintentional touches and provide easy access to editing features, which can be moved and reconfigured based on user input, offering a movable and interactive shortcut toolbar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a touch block object is displayed to block unintentional touches, then unintentional touches are prevented from being registered, but the device complexity increases due to the additional interface element
Solution Approach 1:
The touch block object serves as an intermediary element between the user's hand and the editing canvas. It selectively blocks touch input in its overlay area while allowing touches outside this area to pass through to the canvas, thereby preventing unintentional touches without requiring complex system-level changes
Solution Approach 2:
The touch screen interface is segmented into two distinct zones: a touch-blocked area where the touch block object overlays (preventing input) and a touch-responsive area where the editing canvas remains accessible. This segmentation allows the system to differentiate between intentional and unintentional touches based on location
2Area of stationary object
If editing features are placed at the edge of the screen, then more canvas space is available, but inconvenient large arm movements are required to access these features
Solution Approach 1:
The touch block object is made movable and repositionable on the screen. Instead of fixing editing features at the edge of the screen, the touch block can be moved to bring editing features into more accessible positions while still maintaining adequate canvas space, adding the dimension of dynamic repositioning to the interface
3Ease of operation
If the touch block object is made movable and repositionable, then accessibility to editing features is improved, but the device complexity increases due to additional interaction mechanisms
Solution Approach 1:
The touch block object can be repositioned by simple user gestures (such as dragging with a finger or stylus). The object responds directly to touch input for repositioning itself, eliminating the need for separate menu systems or complex configuration mechanisms to change its position

AI summary
Techniques and systems for facilitating the creation of electronic content on an editing canvas are disclosed. One example involves displaying an editing canvas on a touch screen of an electronic device, displaying a touch block object overlaying a portion of the editing canvas, wherein the touch block object blocks unintentional touches in an area of the touch screen associated with the touch block object, and changing a position of the touch block object with respect to the editing canvas responsive to receiving touch input on the touch screen to change the position of the touch block object. The touch block object may provide easy and convenient access to one or more editing tools or other feature for editing content on the canvas.
