Electronic Device Thermal Alerts Using Grip-State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices, such as mirrorless cameras, face challenges in effectively notifying users of temperature rises or abnormalities without obstructing the view of the live view image, leading to user disturbance during photography.
Innovation Solution
An electronic device equipped with a processor and memory that executes measurement, detection, and control processes to provide a first notification if a specific state is detected, and a more conspicuous second notification if the state is not detected, ensuring user awareness of temperature thresholds without obstructing the live view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large guidance is always displayed to reliably notify the user of temperature warnings, then the notification reliability is improved, but the user's ability to confirm the object (live view image) deteriorates
Solution Approach 1:
The notification display dynamically changes its characteristics based on the detected state of the user. When the user is not holding the camera, a large guidance is displayed for reliable notification. When the user is holding the camera, the display switches to a smaller format that does not obstruct the live view image. This dynamic adaptation resolves the contradiction between notification reliability and ease of operation.
Solution Approach 2:
The display parameters (size, position, or type of notification) are changed based on the detected user state. The system transitions between different notification modes: full-screen or large guidance when the user is absent, and subtle icons or small warnings when the user is present. This parameter change allows the system to maintain notification reliability while preserving the user's ability to view the live image.
2Reliability
If a warning display is performed regardless of whether a video is being recorded, then the notification completeness is improved, but the user disturbance increases
Solution Approach 1:
The notification strategy is localized according to the specific operational context. Different notification behaviors are applied based on whether the device is in photo mode or video recording mode. During video recording, the system suppresses certain notifications to avoid disturbing the user's workflow, while maintaining notification completeness for critical warnings by using subtle, non-intrusive display methods that do not interrupt the recording process.
