AR Content Projection on Body Surfaces for Tactile Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) technologies face challenges in rendering realistic and interactive AR content, as they often lack appropriate physical surfaces for projection, leading to a diminished user experience due to the need for complex gestures and potential obstruction of the physical environment.
Innovation Solution
The approach involves projecting AR content onto readily available and determinable surfaces of a user's body parts, such as hands or forearms, allowing for tactile interaction and simplified gesture recognition, thereby enhancing realism and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR content is displayed at a distance from physical objects or surfaces, then the device can render content without requiring specific physical surfaces, but the perceived realism of the augmented reality experience is detracted
Solution Approach 1:
The system uses the user's body as the projection surface for AR content, eliminating the need for external physical surfaces. The body serves itself as the display medium, providing both the surface for content and the interaction interface, thereby maintaining realism without requiring environmental surfaces.
2Reliability
If traditional AR projection surfaces are used, then environmental context is maintained, but complex gestures are required for interaction and environmental obstruction occurs
Solution Approach 1:
The user's body serves as both the projection surface and the interaction device. Tactile feedback from the body surface itself provides natural interaction without requiring complex hand gestures or external controllers, simplifying operation while maintaining environmental context through body-aware AR rendering.
3Ease of operation
If body surfaces are used for AR content placement, then tactile interaction and simplified gestures are enabled, but the system must detect and track body parts in the environment
Solution Approach 1:
The system uses an intermediary body detection module that processes camera images to identify and track body parts. This intermediary layer translates complex visual data into simplified body part representations, enabling the system to manage the detection complexity while providing simple tactile interaction interfaces.

AI summary
Parts of the body of a user can be used as surfaces for rendering content, such as augmented reality (AR) content. A computing device executing an AR application can detect body parts in an augmented reality view, such as a hand within a field of view of a camera capturing image data for the application. A type of content to be displayed can be determined based on the type and orientation of the body part, in addition to the location and orientation of the device. The content can vary with changes in the orientation of the body part or motion to cause another body part to be visible. A user can make a selection or input for the content by contacting the surface of the body part onto which the content is projected, providing tactile feedback to the user as well as a determinable action for the device.
