Wearable Display Using External Entity as Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices providing augmented reality services face challenges in intuitive user input methods, as they require users to carry separate controllers, which can be inconvenient and limit portability.
Innovation Solution
A wearable device equipped with a display, memory, and a processor that detects and recognizes external entities as controllers using cameras, allowing users to control content through gesture inputs or posture changes, enhancing user experience by utilizing external entities as controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate controller is used to control content on the wearable device, then the user can perform precise control operations, but the portability and convenience of the wearable device is reduced
Solution Approach 1:
The patent uses the camera to capture images of the external entity and creates a virtual copy or representation of that entity. This virtual entity is then used as the controller interface, allowing the user to control content by interacting with the captured image rather than requiring a separate physical controller. The camera captures the external entity, and the processor generates a virtual entity based on the captured image data, which serves as the control interface.
Solution Approach 2:
The patent introduces the camera-captured image of the external entity as an intermediary between the user and the content control system. Instead of directly controlling content with a separate controller or touching the display, the user interacts with the virtual entity (image of external entity) which then mediates the control action. This intermediary approach eliminates the need for separate controllers while maintaining intuitive control.
2Measurement precision
If a separate controller is required for user input, then control precision can be achieved, but the user experience and portability are compromised
Solution Approach 1:
The wearable device uses its own camera to capture the external entity, eliminating the need for separate controllers. The device serves itself by using its built-in camera to obtain the image data of the external entity that will be used as the controller interface. This self-service approach maintains input precision while improving ease of operation.
Solution Approach 2:
The camera serves multiple functions: it captures the external entity for use as a controller, and can also be used for other purposes. The external entity itself becomes universal - it can be any object in the environment, and its captured image serves as the control interface. This multi-functionality approach allows precise control without requiring dedicated controller hardware.
3Ease of operation
If natural user interactions like gestures are used, then ease of operation improves, but the ability to clearly distinguish and recognize specific control inputs decreases
Solution Approach 1:
The patent displays the virtual entity (image of external entity) on the transparent display with visual characteristics that make it distinguishable. The visual entity is presented in a form that allows clear recognition of different control inputs. By rendering the captured external entity as a distinct visual element on the display, the system maintains natural interaction ease while improving input recognition accuracy through visual differentiation.
