Mobile Video Centering via Acoustic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile devices, such as smartphones, face difficulties in maintaining the target subject in the center of the video frame while recording, especially when holding the device at odd angles, as they cannot view the screen, leading to challenges in positioning the device correctly.
Innovation Solution
A computer-implemented method that identifies the intended target and outputs non-visual indications, such as vibrations or audible cues, to guide the user in centering the target within the display, with the indication intensity based on the deviation from the center, allowing for corrective adjustments without visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user holds the mobile device at a high position (e.g., over the user's head) to achieve a desired recording angle, then the recording angle is improved, but the user's ability to view the screen and position the target in the center of the frame deteriorates
Solution Approach 1:
The patent replaces the mechanical visual feedback system (display screen) with an acoustic feedback system (speaker output). The device uses the speaker to provide audio cues about target position and framing, allowing users to record from difficult angles without needing to visually monitor the screen. This substitution enables the user to hold the device in positions that would otherwise make screen viewing impossible.
2Adaptability or versatility
If the user holds the mobile device in positions where screen viewing is difficult, then more recording perspectives are achieved, but the precision of target positioning in the center of the frame deteriorates
Solution Approach 1:
The patent implements an audio feedback mechanism that continuously monitors target position and provides real-time acoustic cues to the user. The speaker outputs directional guidance (e.g., directional arrows or voice instructions) that indicate whether the target is centered or needs adjustment. This feedback loop enables precise target positioning even when the user cannot visually confirm centering on the screen.
3Ease of operation
If an adjustable tilted screen is included to provide visibility at odd angles, then screen visibility is improved, but the device complexity and suitability for compact devices deteriorates
Solution Approach 1:
The patent replaces the mechanical solution of an adjustable tilted screen with an acoustic feedback system. Instead of modifying the physical display structure to accommodate odd angles, the system uses the speaker to provide framing information audibly. This eliminates the need for complex mechanical screen adjustment mechanisms while achieving the same goal of enabling recording from various angles with maintained visibility.

AI summary
A system and method for capturing videos with a mobile device is provided. The method may include identifying, at a computing device, an intended target of a video recording, wherein the intended target is substantially centered within a display of the computing device. The method may include determining, in response to the intended target being out of position, that the intended target is not substantially centered within the display and outputting a non-visual indication that the intended target is not currently substantially centered within the display.
