Crossing-Based Gesture Interface for Multi-Touch Secondary Tasks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-touch devices face challenges in efficiently performing less frequent tasks due to the allocation of primary gestures, leading to cumbersome user experiences and the need for mode switching or additional hardware, which can be costly and consume valuable display space.
Innovation Solution
Implementing a crossing-based interface with activation points near the display edge, allowing gestures between these points and targets on the screen to perform actions, such as selection, annotation, and editing, without interfering with primary gestures and minimizing display space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If primary gestures are allocated to essential interactions (dragging, zooming, tapping), then navigation and viewing functions are improved, but multiple selection and editing tasks become cumbersome and require mode switching
Solution Approach 1:
The display area is segmented into a primary interaction area for standard gestures and a peripheral area for additional functions. The peripheral area is further divided into multiple zones, each associated with different actions (selection, annotation, editing). This segmentation allows primary gestures to remain unchanged while providing access to secondary functions through the peripheral zones.
Solution Approach 2:
The patent introduces a spatial dimension to gesture interpretation by considering the origin point of the gesture. Gestures originating from the peripheral area are interpreted differently than those from the central area. This dimensional addition (spatial origin) enables the system to distinguish between primary navigation gestures and secondary selection/editing gestures without requiring mode switching.
2Adaptability or versatility
If additional hardware or mode switching buttons are added to enable multiple selection, then functionality is improved, but device cost and complexity increase
Solution Approach 1:
The touch display serves multiple functions: it acts as both the display surface and the input interface for all gestures. The peripheral areas of the display are reused to provide additional functionality (selection, annotation, editing) without requiring separate hardware controls. This multi-functionality approach eliminates the need for additional buttons or hardware while expanding device capabilities.
Solution Approach 2:
The display itself provides the control interface for all operations. By utilizing the peripheral areas of the existing display, the system enables multiple selection and editing functions through gestures that originate from these zones. The display serves its own control needs without requiring external or additional hardware components.
3Adaptability or versatility
If virtual buttons are used for mode switching, then functionality is added, but valuable display space is consumed
Solution Approach 1:
Different functional qualities are assigned to different spatial locations on the display. The central area maintains its primary navigation function, while the peripheral areas are assigned specific secondary functions (selection, annotation, editing). This local differentiation allows the system to provide multiple functions without adding visible controls, as each peripheral zone activates its function contextually based on gesture origin.
Solution Approach 2:
The patent extracts the control function from traditional button forms and embeds it into the peripheral areas of the display. Instead of adding separate control elements, the control functionality is extracted and integrated into the existing display boundaries, utilizing otherwise unused peripheral space for functional purposes.
4Adaptability or versatility
If timeouts are used to synthesize additional input states, then multiple selection is enabled, but gestures are penalized with delay
Solution Approach 1:
The system prepares multiple possible input states in advance by defining distinct peripheral zones for different actions. When a gesture originates from a specific peripheral zone, the corresponding action is immediately activated without requiring timeout-based state synthesis. This preliminary arrangement of functional zones enables instant response based on gesture origin, eliminating delays.
