Video Phone Camera Auto Configuration via VRS PTZ Presets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video phone communication systems require manual camera adjustments at the beginning of each call, wasting time and resources, especially for hearing-impaired users who often need interpreter assistance, as the camera is not optimally oriented for the user's location.
Innovation Solution
A method and system for automatic camera configuration in video phones using pre-set Pan Tilt Zoom (PTZ) values stored in a Video Relay Service (VRS) system, allowing the camera to be automatically adjusted for optimal viewing of the hearing-impaired user, reducing setup time and improving translation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual camera adjustment is used at the beginning of each call, then the camera can be positioned to locate a particular location, but valuable time is wasted during setup and interpreters spend time adjusting the camera
Solution Approach 1:
The system performs preliminary action by pre-storing optimal camera positioning data (PTZ presets) in the VRS system before calls are made. When a call is initiated, the stored preset values are automatically retrieved and applied, eliminating the need for manual adjustment during each call setup.
Solution Approach 2:
The system implements self-service by enabling the video phone to automatically configure its own camera settings through the VRS system without requiring manual intervention from users or interpreters. The automatic retrieval and application of PTZ preset values allows the system to self-configure optimal camera positioning.
2Measurement precision
If interpreters manually adjust the camera to obtain an improved view of the hearing-impaired user, then the viewing quality is enhanced, but the cost of live interpreters is very expensive and time is wasted
Solution Approach 1:
The system enables automatic self-configuration of camera settings by retrieving pre-stored PTZ preset values from the VRS system and applying them automatically, eliminating the need for interpreter intervention in camera adjustment while maintaining optimal viewing quality.
Solution Approach 2:
The system replaces the mechanical manual adjustment process performed by interpreters with an automated electronic control system that retrieves and applies stored PTZ preset values, substituting human physical adjustment with automated digital positioning.
3Productivity
If the camera is manually aligned at the beginning of each call, then the camera can be positioned to focus on the user, but the same alignment process must be repeated for every subsequent call
Solution Approach 1:
The system performs preliminary action by pre-storing optimal camera positioning data (PTZ presets) in the VRS system before calls are made. When a call is initiated, the stored preset values are automatically retrieved and applied, eliminating the need for manual adjustment during each call setup.
Solution Approach 2:
The system recovers and reuses previously determined optimal camera positioning data by storing PTZ preset values in the VRS system and retrieving them for subsequent calls, avoiding the waste of repeatedly performing the same camera alignment process.

AI summary
A method and system for automatic camera configuration, upon establishment of a communication session is described. A number is entered into a video phone and a first segment of a communication session is established between the video phone and a service system. The service system retrieves and stores a current default pan, tilt, zoom (PTZ) setting from the video phone camera. The service system transmits the video phone's corresponding camera PTZ preset settings and the video phone configures the camera according to the preset. Upon termination of the communication session, a video relay service (VRS) transmits the default PTZ setting to the video phone and the video phone reconfigures the camera according to the original camera setting.
