Virtual Shutter Button for One-Handed Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to operate electronic devices with large screens for photography or video recording, as pressing a shutter button often blocks the preview picture and requires two hands, leading to a poor user experience.
Innovation Solution
A virtual shutter button is displayed on the electronic device's screen, which can be moved to a convenient position for one-handed operation, allowing users to perform photography or video recording without obstructing the preview image, and can be disabled based on specific conditions or user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shutter button is displayed on the photographing preview interface, then the user can perform photographing operation, but the user's hand blocks the preview picture during operation
Solution Approach 1:
The shutter button is extracted from the center of the photographing preview interface and relocated to the edge region. This separation removes the obstruction from the preview picture area while maintaining the photographing function, allowing users to operate with one hand without blocking the view.
Solution Approach 2:
The shutter button is moved from the two-dimensional center position to the edge region, utilizing the spatial dimension of the interface layout. This repositioning allows the button to be accessible for one-handed operation while keeping the preview picture area clear.
2Ease of operation
If the shutter button is positioned in the center of the screen, then it is easily accessible, but it obstructs the preview picture for large screen devices
Solution Approach 1:
The shutter button is extracted from the center position and relocated to the edge region. This removes the obstruction from the preview picture area while maintaining accessibility through the edge location, which is still easily reachable for users.
Solution Approach 2:
Different regions of the interface are assigned different qualities: the edge region accommodates the shutter button for accessibility, while the center region maintains a clear preview picture area. This local differentiation optimizes both accessibility and preview quality.
3Adaptability or versatility
If multiple shutter buttons are displayed on the interface, then users have more operation options, but the interface complexity increases
Solution Approach 1:
The shutter button function is segmented into different types (first shutter button for photographing, second shutter button for video recording) displayed at different positions. This segmentation provides multiple operation options while keeping each button simple and the interface organized.
Solution Approach 2:
The interface design accommodates multiple shutter buttons with different functions at different positions, allowing a single interface to serve multiple photographing needs (still image, video recording) without requiring separate applications or complex navigation.

AI summary
This application provides a photographing method and an electronic device. In the photographing method, a virtual shutter button is provided on a photographing preview interface, and a user implements a photographing or video recording function by tapping the virtual shutter button. The virtual shutter button has a same function as a shutter button of a camera application. When the user uses the photographing function of the electronic device, the virtual shutter button may move on the photographing preview interface based on a touch input of the user, thereby improving photographing experience of the user. In addition, the user may complete a photographing operation by touching and tapping the virtual shutter button, and therefore, shake caused by taking a photo by pressing a mechanical button (for example, a volume button) is avoided, and quality of a captured photo is ensured. In this way, different photographing requirements of the user can be met, thereby improving photographing experience of the user.
