Dynamic Gesture Icons for Mobile Device Discoverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile computing devices are often unaware of the gestures required to trigger specific actions, leading to confusion and inefficiency in interacting with these devices.
Innovation Solution
The implementation of visual indicators that represent physical objects associated with predefined gestures, providing feedback to users as they perform actions, such as twisting the device to answer a call, which is represented by a door opening, enabling intuitive learning of gestures that trigger device actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual indicators are provided to guide users through gestures, then gesture discoverability is improved, but device complexity increases
Solution Approach 1:
The system provides real-time visual feedback by displaying dynamic icons that respond to device orientation changes. As the user rotates the device toward the correct gesture position, the icon visually transforms to indicate progress, confirming the user's actions and guiding them toward completing the gesture successfully.
Solution Approach 2:
Dynamic visual icons serve as an intermediary between the user's physical gestures and the device's response actions. The icons translate complex gesture requirements into intuitive visual metaphors (e.g., a door opening, a bottle pouring), making the abstract gesture concepts accessible and understandable to users.
2Loss of information
If dynamic visual indicators are displayed to represent gesture progress, then user understanding is improved, but energy consumption increases
Solution Approach 1:
The visual indicators are updated periodically based on the device's orientation changes rather than continuously. The system detects when the device reaches significant orientation milestones during gesture execution and updates the icon accordingly, reducing unnecessary processing and display refreshes while maintaining effective visual guidance.
3Adaptability or versatility
If multiple gesture options are available, then device functionality is improved, but ease of operation deteriorates due to user confusion
Solution Approach 1:
The system applies different visual indicator types and metaphors tailored to specific gesture contexts and functions. Each gesture type receives a customized visual representation that matches its purpose (e.g., rotational gestures use circular progress indicators, linear gestures use bar indicators), making it easier for users to understand and execute the appropriate gesture for their needs.

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing gesture discoverability with a mobile computing device. In one aspect, a method includes actions of obtaining gesture definition data for a particular gesture. The gesture definition data specifies a predefined onset position associated with commencement of the particular gesture, a predefined motion associated with completion of the particular gesture, a particular action that is triggered upon the completion of the particular gesture, and a visual indicator for visually indicating a progress toward the completion of the particular gesture as the predefined motion is performed. Additional actions include determining that an orientation of a mobile computing device matches the onset position of the particular gesture, providing the visual indicator, determining a motion, determining whether the motion matches the predefined motion, and determining whether to update the visual indicator.
