Telepresence Robot Camera View Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telepresence robots fail to provide users with a strong sense of presence, as they cannot move in concert with the user at the remote location, limiting the feeling of the partner's presence during communication.
Innovation Solution
A remote communication system that includes a robot capturing an image of a user in one location and transmitting it to a presentation device in another location, which detects changes in the user's position and orientation, allowing the robot to adjust its camera view to mimic the movement, thereby creating a sense of presence as if the user were present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot remains stationary to maintain stable image capture, then the communication system is simple to operate, but the user cannot experience the feeling of presence as if the partner were physically present in the remote location
Solution Approach 1:
The robot transitions from a stationary state to a dynamic state by automatically moving to positions that correspond to the remote user's movements. The robot's movement is dynamically adjusted based on position change information received from the remote side, allowing the local user to experience presence feelings while maintaining automatic control that preserves operational simplicity.
Solution Approach 2:
The system implements a feedback loop where the robot receives position change information from the remote user's movements and automatically adjusts its position and camera orientation accordingly. This feedback mechanism enables the robot to respond to remote user actions, creating a synchronized experience that enhances the sense of presence without requiring complex manual operation.
2Reliability
If the robot automatically moves to follow the remote user's position changes, then the user experiences a strong sense of presence, but the system complexity increases due to automated movement control and coordinate transformation
Solution Approach 1:
The system creates a virtual copy of the remote user's position and orientation data and applies it to control the robot's movement and camera orientation. Instead of complex direct control, the robot replicates the remote user's spatial behavior through automated coordinate transformation and position mapping, simplifying the control architecture while achieving realistic presence effects.
3Stability of the object's composition
If the camera view remains fixed to provide stable image quality, then the communication connection is stable, but the local user cannot perceive the remote user's movements and orientation changes
Solution Approach 1:
The camera system transitions from a fixed static view to a dynamic view that automatically adjusts based on remote user position changes. The camera's orientation and position are dynamically modified to follow the remote user's movements, allowing the local user to perceive motion and spatial changes while maintaining continuous stable communication connection.
Solution Approach 2:
The camera receives feedback information about the remote user's position and orientation changes, and automatically adjusts its viewing angle and position accordingly. This feedback-driven camera control enables the local user to perceive the remote user's movements and spatial relationships while maintaining image quality and connection stability.

AI summary
A remote communication method of a remote communication system including a first robot deployed in a first place and a first presentation device deployed in a second place, includes capturing an image of a first user in the first place with a camera, transmitting the captured image of the first user from the first robot to the first presentation device, receiving the captured image from the first robot, displaying the captured image, detecting a first amount of change indicating a change in a position of a second user in the second place with reference to a second robot that virtually represents the first user, transmitting the first amount of change to the first robot, receiving the first amount of change from the first presentation device, and moving the first robot to change a point of view of the camera in response to the first amount of change.
