VR Drone Haptic Feedback Body Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems fail to adequately immerse users through the sense of touch, often relying on stationary mechanical devices that constrain user motion and do not provide comprehensive body-wide haptic feedback.
Innovation Solution
A virtual reality system incorporating a drone with a rotor, display, audio speaker, and adjustable body harness, where processors control the drone's audio-visual content and rotor operations to provide immersive haptic feedback without constraining user motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If stationary mechanical devices are used to provide haptic feedback, then tactile sensation is improved, but user motion freedom deteriorates
Solution Approach 1:
The patent replaces stationary mechanical devices with a dynamic drone system that can move freely in three-dimensional space. The drone is suspended by cables from overhead tracks, allowing it to position itself dynamically around the user and adjust its location in response to virtual environment events, thereby providing haptic feedback without constraining user motion.
Solution Approach 2:
The patent substitutes traditional mechanical haptic devices (robotic plates or arms) with an aerial drone system. This replacement eliminates the need for ground-based mechanical constraints while maintaining the ability to deliver tactile feedback through the drone's position changes, movements, and interactions with the user's personal space.
2Ease of operation
If handheld controllers with vibrations are used, then tactile feedback is provided, but body-wide immersion deteriorates
Solution Approach 1:
The patent transitions haptic feedback from the handheld controller dimension to a three-dimensional aerial space. The drone operates in the user's personal space above and around them, creating a spatially distributed haptic experience that engages the entire body rather than just the hands, thereby achieving body-wide immersion.
Solution Approach 2:
The drone serves multiple functions simultaneously: it acts as a visual element in the virtual environment, a haptic feedback device through its movements and position changes, and an audio delivery system. This multi-functionality replaces the limited tactile feedback of handheld controllers with a comprehensive sensory experience.

AI summary
A virtual reality system includes a drone including a rotor, a display, an audio speaker, a body harness having adjustable straps, and one or more processors in operative communication with the display, the audio speaker, and the drone. The drone may be fixed to the body harness. The one or more processors may be configured to issue audio-visual content to the display and audio speaker and control the rotor based on the issued audio-visual content.
