Simultaneous Focus and View Pointing in User Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces require users to switch between distinct modes for scrolling, zooming, and selecting interactive items, leading to inefficiencies and repetitive 'point and click' actions, as they cannot perform these actions simultaneously.
Innovation Solution
A method that allows simultaneous focus pointing and view pointing by detecting movements along predefined axes, enabling seamless navigation and selection of interactive items without the need to alternate between modes, using a combination of vertical and horizontal axis movements to control zooming, panning, and scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distinct modes are used for scrolling, zooming, and selecting interactive items, then each action can be performed with dedicated control, but the user interface complexity increases and multiple actions cannot be performed simultaneously
Solution Approach 1:
The patent combines multiple distinct target-directed movement modes (view pointing, focus pointing, scrolling, zooming) into a single unified interaction framework. A single pointer device and set of input actions can simultaneously or sequentially perform multiple functions without requiring mode switching, thereby reducing device complexity while maintaining operational ease.
Solution Approach 2:
The pointer device and control mechanism are designed to be universal, capable of performing multiple functions (scrolling, zooming, panning, selecting) without requiring separate dedicated controls or mode changes. This multi-functionality eliminates the need for complex mode switching mechanisms while preserving the ability to perform each action effectively.
2Measurement precision
If multiple target-directed movements are performed as distinct modes, then each movement type can be controlled precisely, but the time required to complete navigation and selection increases
Solution Approach 1:
The patent enables continuous target-directed movement where the pointer can smoothly transition between different movement types (view pointing, focus pointing, scrolling, zooming) without interruption or mode switching. This continuity allows the user to perform multiple actions in a single continuous motion, significantly reducing the time required to locate and select target items while maintaining precise control throughout the movement.
Solution Approach 2:
The system performs preliminary actions automatically based on pointer movement intent. As the user moves the pointer toward a target, the system anticipates the desired action (scrolling, zooming, panning) and executes it in advance or concurrently with the pointer movement, eliminating the need for separate sequential actions and reducing overall task completion time.
3Reliability
If separate actions are required for view pointing and focus pointing, then each action can be executed with full attention, but the overall interaction efficiency decreases
Solution Approach 1:
The patent merges view pointing and focus pointing into a single unified interaction process. The pointer device simultaneously handles both tasks - adjusting the view (scrolling, zooming, panning) and positioning the selection target - without requiring separate actions. This combination maintains reliable item selection while dramatically improving interaction efficiency by eliminating redundant movements and mode switches.
Data Source
AI summary
The invention provides a method of interacting with interactive items in a user interface. A user interface is provided which includes a control region and a display region. A plurality of interactive items are displayed in the display region. The user interface tracks the position and movement of a pointer in the control region, and interprets the movement and/or position of the pointer. Movement along a first predefined axis is interpreted as focus pointing only, movement along a second predefined axis is interpreted as view pointing only. Movement having components along both axes is interpreted as both view pointing and focus pointing, enabling both view pointing and focus pointing to be substantially simultaneously performed.
