Remote Medical Face Video Transmission Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remote medical operations struggle to balance the transmission of operation videos with privacy protection, particularly in determining whether to share a patient's face with remote doctors, and ensuring that important facial changes are communicated effectively.
Innovation Solution
An information processing apparatus and method that dynamically select a transmission mode for face videos based on predefined settings for the remote terminal, either transmitting feature points of the patient's face or compressed face videos, to ensure appropriate privacy and communication standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a video showing a patient's face is transmitted to a remote terminal, then the doctor can grasp the change in the patient's face for diagnosis, but the patient's privacy is compromised
Solution Approach 1:
The patent extracts only the necessary facial feature points (coordinates, distances, areas) from the complete face video, transmitting only this extracted information to the remote terminal. This allows the doctor to observe facial changes without exposing the patient's identity or full facial appearance, thus resolving the contradiction between information transmission and privacy protection
Solution Approach 2:
The face video is segmented into discrete feature points (e.g., 68 landmarks) rather than transmitting the continuous video stream. Each feature point represents specific facial characteristics, allowing precise tracking of facial changes while maintaining privacy by not transmitting the complete visual image
2Quantity of substance
If a compressed face video is transmitted instead of feature points, then the transmission data量 is reduced, but the precision of facial change information is lost
Solution Approach 1:
Instead of transmitting compressed video data, the patent extracts specific numerical features (coordinates, distances, areas) directly from the face video frames. This extraction approach transmits only the essential measurement data needed for diagnosis, achieving both data volume reduction and preservation of measurement precision
Solution Approach 2:
The patent transforms visual facial information into numerical parameters (coordinates of feature points, distances between points, areas of regions). This parameter transformation allows precise quantitative representation of facial changes while significantly reducing data volume compared to video transmission
3Object-affected harmful factors
If feature point information is transmitted instead of compressed video, then privacy is better protected, but the data transmission volume is increased
Solution Approach 1:
The patent converts facial visual information into compact numerical parameters (coordinates, distances, areas). Although more detailed than compressed video, these parameters are significantly more efficient than full video data while providing superior privacy protection by not transmitting recognizable facial images

AI summary
The present technology relates to an information processing apparatus, an information processing terminal, an information processing method, and a program each adapted to be capable of appropriately selecting a mode for transmitting information regarding an expression. An information processing apparatus according to a first aspect of the present technology sets, in a case where an operation video requested from a remote terminal is a face video possibly showing a patient's face, a transmission mode on the basis of a transmission setting defined for the remote terminal to which the face video is transmitted, transmits information on a feature point of the patient's face extracted from the face video to the remote terminal in a case where a first transmission mode is set, and transmits the compressed face video to the remote terminal in a case where a second transmission mode is set. The present technology is applicable to a remote operation system for instructing an operator in an operating room on how to conduct an operation from a remote location.
