Wearable Camera Circular Buffer for Hands-Free Event Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable video recording (PVR) camera equipment is cumbersome and limits user participation in activities, and existing 'hands-free' solutions are impractical for everyday use, often resulting in missed events due to delayed recording initiation.
Innovation Solution
A video recording camera system with a non-volatile memory configured as a circular buffer, integrated into a wearable headset that records video and audio, allowing continuous recording and wireless transmission of video frames to a communication handset, enabling hands-free operation and real-time event capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional PVR camera equipment is used, then video recording capability is provided, but the equipment is cumbersome and limits user participation in activities
Solution Approach 1:
The system separates the video recording function into a remote wearable camera unit from the control interface located in the user's pocket. This segmentation allows the recording device to be hands-free while the control functions remain accessible, resolving the contradiction between ease of operation and device portability.
Solution Approach 2:
The wearable camera is positioned in the user's field of view, effectively nesting the recording device within the user's personal space. The control phone is then nested within the user's pocket, creating a hierarchical arrangement that minimizes physical burden while maintaining functionality.
2Ease of operation
If hands-free PVR camera equipment is used, then user mobility is improved, but the configurations are cumbersome and impractical for everyday use
Solution Approach 1:
The system uses a universal remote control interface (smartphone) that the user already possesses and is familiar with. This multi-functional device serves as the control interface for the wearable camera, eliminating the need for dedicated controls on the camera itself and simplifying the overall configuration.
Solution Approach 2:
The smartphone acts as an intermediary between the user and the wearable camera. Rather than requiring direct interaction with the camera's controls, the user interacts with the familiar phone interface, which then communicates with the camera wirelessly, simplifying the user experience.
3Loss of time
If traditional PVR camera equipment is carried in pocket, then accessibility is improved, but recording initiation is delayed causing missed events
Solution Approach 1:
The wearable camera is positioned in advance in the user's field of view and kept in standby mode with recording capability immediately available. This preliminary positioning eliminates the delay of retrieving and setting up the camera when an event occurs, as the camera is already in the optimal position and ready to record.
Solution Approach 2:
The system maintains continuous readiness for recording through the wearable camera's persistent presence in the user's field of view. The camera remains active and responsive to recording commands at all times, ensuring that no event is missed due to retrieval or setup delays.
Data Source
AI summary
A video recording camera system provide remote control functionality through a wireless handset interface. In embodiments, a video recording camera includes an optical sensor, a processor coupled to the optical sensor to process an input image signal received from the optical sensor into an encoded video data stream, a non-volatile storage medium coupled to the processor to store, locally in the video recording camera, encoded video data stream as recorded video data, and a wireless transceiver. In embodiments, a cellular-enabled wireless communication handset communicatively couples to the video recording camera over a wireless personal area network (WPAN) supported by the camera's wireless transceiver. The handset serves as a gateway to the camera providing access to recorded video data or functions of the camera, via the WPAN, as determined based on communications conducted by the handset over a cellular communication link.
