Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is given to prompt the user to make settings, then the user can be informed about the need for calibration, but the display may annoy the user depending on the orientation of the digital camera
Solution Approach 1:
The patent applies local quality by making the display behavior orientation-dependent. The control unit selectively displays calibration prompts only when the digital camera is in a predetermined orientation (e.g., horizontal position), while suppressing the display in other orientations (e.g., vertical position). This resolves the contradiction by adapting the information provision to the specific operational context, ensuring users are informed when calibration is actually needed without causing annoyance during normal vertical usage.
2Measurement precision
If calibration data is set to match the user's eyeball rotation angle with the gaze point, then line-of-sight detection accuracy is improved, but the setting complexity increases
Solution Approach 1:
The patent implements self-service by enabling the digital camera to automatically perform calibration operations without requiring manual user configuration. The control unit automatically adjusts calibration data based on detected usage patterns and orientation information, matching the user's eyeball rotation angle with the gaze point autonomously. This maintains high line-of-sight detection accuracy while eliminating the complexity of manual calibration settings for the user.
Solution Approach 2:
The patent applies preliminary action by performing calibration in advance during specific orientations or conditions before actual line-of-sight detection is needed. The system proactively adjusts calibration data when the camera is in predetermined orientations, ensuring accuracy is established beforehand rather than requiring complex real-time adjustments during usage.
3Ease of operation
If the electronic device provides setting prompts regardless of orientation, then all users are informed about function settings, but users may be annoyed during certain orientations
Solution Approach 1:
The patent applies dynamics by making the display behavior adaptive and changeable based on device orientation. The control unit dynamically adjusts whether to display calibration prompts according to the current orientation detected by the orientation detection unit. This resolves the contradiction by transitioning from a static always-on display approach to a dynamic context-aware approach that provides information when useful and remains silent when potentially annoying.

AI summary
An electronic device includes setting means configured to set a predetermined function related to control of the electronic device and capable of being performed regardless of an orientation of the electronic device, orientation detection means configured to detect the orientation of the electronic device, and control means configured to perform control such that in a case where the orientation detection means detects that the electronic device is in a first orientation, a first display is given on display means to prompt to set the predetermined function depending on a setting state of the predetermined function wherein the first display includes a display item for instructing to set the predetermined function by a user operation, and in a case where the orientation detection means detects that the electronic device is in a second orientation different from the first orientation, the first display is not given.
