Presentation Device Control Using Head-Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-person meetings often require tedious and time-consuming adjustments of presentation devices, leading to inefficiency and potential distraction or power waste due to inadequate control of multiple devices during transitions.
Innovation Solution
An electronic device that monitors attendee head positions to determine which presentation device is being used and controls device settings like illumination and audio volume based on these positions, optimizing device usage and minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustments of presentation devices are performed during meetings, then device control can be achieved, but meeting efficiency decreases due to tedious and time-consuming operations
Solution Approach 1:
The system enables presentation devices to automatically adjust their own settings based on detected head positions of attendees. The electronic device monitors head positions and autonomously controls illumination levels, audio volume, and device switching without requiring manual intervention from presenters or attendees, thus resolving the contradiction between device control and meeting efficiency
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated electronic control system that uses camera-based head position detection and electronic signaling to control presentation devices. This substitution eliminates the need for physical interaction with device controls during meetings, thereby improving efficiency and reducing time loss
2Adaptability or versatility
If multiple presentation devices are kept on during meetings, then device availability is maintained, but energy consumption increases
Solution Approach 1:
The system periodically monitors head positions of attendees and dynamically adjusts the operational state of presentation devices based on detected usage patterns. Devices are turned on or off in periodic cycles according to actual need, maintaining availability when required while reducing energy consumption during periods of non-usage
Solution Approach 2:
The system applies different operational states to different presentation devices based on local conditions - specifically, which device is currently being viewed by attendees. Only the relevant presentation device maintains full power and illumination, while other devices are dimmed or turned off, thereby preserving adaptability while reducing overall energy consumption
3Ease of operation
If presentation devices are adjusted manually during transitions, then device switching can be performed, but attendee distraction increases
Solution Approach 1:
The system detects head positions in advance and anticipates which presentation device the presenter intends to use next. By proactively preparing and switching devices based on predicted intent rather than waiting for manual commands, the system performs adjustments before they would disrupt the meeting flow, thereby maintaining ease of operation while minimizing attendee distraction
Solution Approach 2:
The system continuously monitors head positions of attendees and presenters as feedback signals to determine when device switching is needed. This real-time feedback mechanism enables automatic, context-aware device transitions that occur smoothly without requiring manual intervention that would distract attendees from the presentation content

AI summary
In examples, an electronic device comprises a camera to capture an image of a space and a processor coupled to the camera. The processor is to receive the image of the space from the camera; identify a person in the image and a presentation device in the image; identify a head position of the person based on the image; determine whether the person is viewing the presentation device based on the head position; and perform an action relating to the presentation device based on the determination.
