Smart Glasses Temple Arm Gesture Hierarchy for Easier Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of augmented-reality headsets face challenges in remembering and learning a large number of input gestures, limiting their ability to perform diverse operations efficiently.
Innovation Solution
Implementing a multi-tiered input gesture hierarchy that allows users to perform multiple operations using fewer gestures by switching between multi-modal and non-multi-modal gestures based on the availability of input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input gestures are provided to perform diverse operations, then the versatility of the user interface is improved, but the complexity of learning and remembering gestures increases
Solution Approach 1:
The patent implements a universal gesture system where a single input gesture (e.g., temple arm tap) can perform multiple operations depending on the current context and mode. The system switches between multi-modal gesture mode (when coupled device is available) and non-multi-modal gesture mode (when coupled device is unavailable), allowing the same gesture to trigger different actions based on system state rather than requiring users to learn separate gestures for each function.
Solution Approach 2:
The gesture interpretation is made dynamic by changing the meaning of gestures based on the availability of the coupled device. The system dynamically switches between two operational modes: multi-modal gesture mode where gestures control the coupled device, and non-multi-modal gesture mode where gestures control local functions. This dynamic reassignment allows versatile operation with a limited gesture set.
2Ease of operation
If a multi-tiered input gesture hierarchy is implemented to reduce the number of gestures, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The gesture system is segmented into two distinct modes or tiers: multi-modal gesture mode and non-multi-modal gesture mode. Each mode has its own gesture interpretation rules and operational context. The system divides the gesture processing logic into separate handling paths based on the availability state of the coupled device, making the overall system manageable through clear segmentation of functionality.
Solution Approach 2:
The system introduces an intermediary layer (the mode switching mechanism) that sits between the gesture input and the action execution. This intermediary determines which gesture interpretation rules to apply based on the coupled device availability state. The mode switch acts as a mediator that translates the same physical gesture into different logical commands depending on system context, managing complexity by adding a controlled decision layer.

AI summary
An example method of interacting with a pair of smart glasses, includes receiving a swipe gesture at a location on a temple arm of the pair of smart glasses, and in response to receiving the swipe gesture, performing an operation at the pair of smart glasses associated with the swipe gesture. The method also includes receiving a different input at the location on the temple arm of the pair of smart glasses, and in response to receiving the different input at the location, invoking a virtual assistant that is configured to execute voice commands. The method further includes receiving another input at a different location on the temple arm, and in response to receiving the other input, performing another operation at the pair of smart glasses associated with the other input.
