Dual Perspective View for VR Therapy Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems for therapy lack an efficient user interface to simultaneously display both Spectator View and Live Avatar View, which are crucial for monitoring patient safety and therapeutic guidance, often requiring therapists to switch between views or sacrifice display size, leading to reduced visibility and increased complexity.
Innovation Solution
The implementation of a Dual Perspective View that overlays a translucent Live Avatar View onto the Spectator View, allowing both views to be maximized on the same screen without occluding each other, thereby enhancing visibility and simplifying the monitoring process for therapists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If Spectator View and Live Avatar View are displayed on separate screens or windows, then both views can be shown simultaneously, but the display area for each view is reduced and the interface complexity increases
Solution Approach 1:
The patent combines Spectator View and Live Avatar View into a single integrated display interface. The Live Avatar View is overlaid on top of the Spectator View, allowing both views to occupy the same screen space simultaneously. This merging eliminates the need for separate windows or screens, maximizing the use of display area while maintaining visibility of both patient movements and virtual environment.
Solution Approach 2:
The Live Avatar View is nested within the Spectator View display area. The avatar rendering is positioned in the foreground layer while the Spectator View content remains visible in the background layer, creating a nested visual hierarchy. This allows the avatar to be observed without completely blocking the underlying virtual environment and patient movement information.
2Loss of information
If both Spectator View and Live Avatar View are displayed simultaneously on the same screen in separate windows, then both views are visible, but each view's display size is reduced
Solution Approach 1:
Instead of allocating separate window spaces for Spectator View and Live Avatar View, the patent merges them into a unified display where the avatar is overlaid on the virtual environment. This allows the full screen area to be utilized for both views simultaneously, with the avatar occupying only a portion of the display while the Spectator View fills the remaining background space.
Solution Approach 2:
The patent introduces a layered dimensional structure where the Live Avatar View exists in the foreground layer and the Spectator View exists in the background layer. This vertical layering approach allows both views to coexist without horizontally dividing the screen space, effectively utilizing the z-dimension of display layers to maximize two-dimensional screen real estate for both views.
3Reliability
If therapists switch between Spectator View and Live Avatar View to monitor patient safety, then detailed observation is possible, but time is lost and monitoring continuity is interrupted
Solution Approach 1:
The patent merges both monitoring perspectives into a single simultaneous display, eliminating the need for therapists to switch between views. The Spectator View provides the virtual environment context while the Live Avatar View shows real-time patient movements, allowing continuous uninterrupted monitoring of both aspects of patient safety in real-time.
Solution Approach 2:
The integrated display enables continuous monitoring of patient safety without interruption. By showing both Spectator View and Live Avatar View simultaneously, the system maintains unbroken visual feedback to the therapist, allowing continuous observation of patient movements and virtual environment interactions without the breaks that would occur when switching between separate views.

AI summary
Systems and methods are described to render a Live Avatar View third-person view as an overlay of a first person Spectator View, as mirrored from a Virtual Reality headset, in a Dual Perspective View. In some embodiments, a clinician tablet may display Dual Perspective View with a full screen Spectator View, to maximize visibility, and render a translucent avatar from Live Avatar View (LAV) to overlay the Spectator View for simultaneous visibility during a therapy session. Spectator View may be critical to monitor for therapy guidance and an LAV conveys valuable movement and safety data. A translucent avatar overlay and activity cues allows monitoring the avatar from Live Avatar View in a way that would not block the Spectator View or occlude other body parts potentially hidden.
