Multiple-Display Camera Control for Collaborative Self-Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with multiple displays struggle to allow both the capturer and the subject to change camera settings during a selfie or full-body shot, especially when the subject's hand cannot reach the device.
Innovation Solution
An electronic device with multiple displays is configured to display camera application functions on both displays, allowing the subject to change camera settings using gaze or gestures, while the capturer can also manipulate settings on their display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are provided to enhance user convenience and functionality, then the utility and display capabilities of the electronic device are improved, but the complexity of the device increases and it becomes difficult to properly utilize the advantages of multiple displays for collaborative capture operations
Solution Approach 1:
The user interface is segmented across multiple displays (first display for capturer, second display for subject), allowing each user to interact with the system independently on their respective display. This segmentation enables collaborative capture operations while maintaining manageable complexity through distributed functionality.
2Ease of operation
If the subject is positioned to take a selfie with hand reaching the device, then the subject can control camera settings, but the subject cannot properly use advanced functions of the rear camera which requires capturer operation
Solution Approach 1:
The control interface is divided into two independent parts: first screen for capturer operations and second screen for subject operations. Each screen can be independently controlled by the respective user, enabling both capturer and subject to perform their intended operations simultaneously without interference.
Solution Approach 2:
The system transitions from a single-point-of-control interface to a multi-dimensional interface distributed across spatially separated displays. The subject can gesture at the second display while the capturer operates the first display, adding a spatial dimension to the control interaction.
3Ease of operation
If the subject's hand reaches the device to change camera settings, then the subject can adjust settings directly, but the subject cannot remain in the optimal position for capturing themselves where hand reach is limited
Solution Approach 1:
The system replaces the mechanical hand-operated control interface with a gesture-based interaction system. The subject can control camera settings on the second display through hand gestures without needing to physically reach the device, allowing optimal positioning for self-capture while maintaining control capability.
Solution Approach 2:
The second display acts as an intermediary between the subject and the camera control system. Instead of directly manipulating the device, the subject interacts with the displayed interface through gestures, with the system translating these gestures into control commands.
4Ease of operation
If both capturer and subject can independently change camera settings during capture, then user convenience and satisfaction are enhanced, but conflicts may occur when both users attempt to modify the same settings simultaneously
Solution Approach 1:
The setting change mechanism is segmented into independent control paths: capturer controls first screen settings while subject controls second screen settings. The system tracks which user is controlling which settings and prevents conflicts by managing control states across the distributed interface.
Solution Approach 2:
The system provides feedback to indicate whose control is active and whose settings are currently being modified. This feedback mechanism helps coordinate between capturer and subject, allowing them to take turns or work together on setting changes without unintended conflicts.

AI summary
An electronic device is provided. The electronic device includes a camera module, a first display, a second display, and at least one processor. The at least one processor may be configured to display a first screen and a second screen for displaying at least one function of a camera application on the first display facing in a first direction and the second display facing in a second direction opposite to the first direction, respectively, wherein at least one of the first screen or the second screen includes an image obtained through the camera module, identify a first input for selecting a first function of the camera application through the first screen, identify a second input related to a subject's gaze or gesture in a state in which the first function of the camera application is selected through the first screen, and display, on the second screen, in a state in which the first function of the camera application is selected through the first screen, an indication indicating that selection of the first function by the second input related to the subject's gaze or gesture is restricted.
