Electronic Device Orientation Control for Line-of-Sight Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with line-of-sight detection accuracy and user annoyance due to orientation-dependent displays prompting for settings, which can disrupt the user experience.
Innovation Solution
An electronic device with orientation detection means that controls the display of setting prompts based on the device's orientation, providing a first display for setting a function in a specific orientation and omitting it in others, ensuring timely and user-friendly setting prompts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is given to prompt the user to make settings regardless of device orientation, then the user is informed about the need for calibration, but the display may annoy the user depending on the orientation of the device
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 device is in a first orientation (e.g., horizontal position), while suppressing the same prompt when the device is in a second orientation (e.g., vertical position). This localized approach to information display ensures that calibration reminders are shown only in contexts where they are useful and not annoying to users.
2Measurement precision
If calibration data is set to match user's eyeball rotation angle with gaze point, then line-of-sight detection accuracy is improved, but the user cannot recognize the discrepancy when calibration is not set
Solution Approach 1:
The patent implements feedback by having the control unit monitor the calibration status and provide visual feedback to the user through display prompts. When calibration data is not set or is incomplete, the system displays a prompt on the display unit to inform the user that calibration is needed. This feedback mechanism bridges the information gap, allowing users to understand when calibration is necessary without directly observing the internal calibration status.
3Reliability
If setting prompts are displayed in all orientations, then the function setting is ensured, but the display may be annoying and disrupt user experience in certain orientations
Solution Approach 1:
The patent applies dynamics by making the display behavior adaptive to device orientation. The control unit dynamically adjusts whether to display calibration prompts based on real-time orientation detection from the orientation detection unit. This dynamic approach ensures that setting prompts are displayed reliably when needed (in the first orientation) while automatically suppressing them when they would be disruptive (in the second orientation), thus maintaining both reliability and user experience.

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.
