Virtual Object Manipulation with Gaze and Hand Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with augmented and virtual reality environments are cumbersome, inefficient, and place a significant cognitive burden on users, requiring multiple inputs and leading to errors, thus wasting energy and being suboptimal for battery-operated devices.
Innovation Solution
Improved user interfaces for computer systems that utilize a combination of touch-sensitive displays, eye-tracking, hand-tracking, and tactile output generators to facilitate more intuitive and efficient interaction with virtual objects, reducing the number and complexity of user inputs and providing enhanced feedback.

Engineering Contradiction Analysis
1Ease of operation
If conventional input methods (multiple buttons, menus, and gestures) are used to interact with virtual objects, then the system can achieve precise control and manipulation, but the user experiences cognitive burden, increased error rates, and longer interaction time
Solution Approach 1:
The system provides immediate visual feedback by highlighting the selected virtual object and showing possible actions, helping users understand system state and reduce cognitive burden. This feedback mechanism allows users to navigate and manipulate objects more efficiently without needing to remember complex command sequences.
Solution Approach 2:
The system automatically presents relevant actions and information based on the current context and user selection, eliminating the need for users to search through menus or remember available commands. The interface adapts to user needs, showing only relevant options and reducing interaction steps.
2Productivity
If conventional input methods requiring multiple sequential inputs are used, then the system can perform complex manipulations, but the energy consumption increases and battery life decreases
Solution Approach 1:
The system maintains continuous tracking of the user's gaze and hand position, allowing for seamless transitions between viewing and manipulating virtual objects. This continuity eliminates the need to re-acquire targets or re-establish context, reducing the number of discrete input actions required and thereby lowering energy consumption.
Solution Approach 2:
The system extracts and utilizes natural user behaviors (gaze direction, hand movement) as input signals, eliminating the need for deliberate button presses or complex gesture sequences. By taking out the cognitive overhead of traditional input methods, the system reduces both interaction time and energy consumption while maintaining manipulation efficiency.
3Measurement precision
If detailed feedback mechanisms are implemented to guide users, then user understanding and precision improve, but the interface complexity and cognitive load increase
Solution Approach 1:
The system provides feedback and information locally at the point of interaction, highlighting the selected object and showing actions contextually near the object. This localized feedback approach improves selection accuracy without requiring global interface changes or increasing overall complexity, as each area of the interface provides only the information relevant to that specific context.
