Camera UI Gesture Switching for Mobile Photography Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera-equipped mobile computing devices face usability challenges due to the limitations of traditional camera controls on presence-sensitive displays, which cannot easily accommodate dedicated buttons and physical widgets, making it difficult to seamlessly switch between standard-lens and wide-angle photography modes.
Innovation Solution
Implementing a method that allows users to switch between standard-lens and wide-angle photo capture UIs by receiving specific input gestures, such as 'zoom-out' or 'zoom-in' commands, to adapt the UI to the device's focal length, enabling intuitive and discoverable transitions between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional camera controls with dedicated buttons and physical widgets are used, then camera operation is straightforward and reliable, but the controls are not feasible or wieldy on mobile computing devices with presence-sensitive displays
Solution Approach 1:
The patent replaces physical camera controls (buttons, widgets) with gesture-based controls on a presence-sensitive display. Users perform gestures such as rotating their hand clockwise or counterclockwise in front of a sensor to switch between photo capture modes, eliminating the need for physical camera control hardware on the mobile device.
Solution Approach 2:
The patent introduces an intermediary sensor system that detects hand gestures and translates them into camera control commands. The sensor acts as a mediator between the user's physical gestures and the camera software, enabling indirect control of photo capture modes through gesture recognition rather than direct button presses.
2Adaptability or versatility
If multiple photo capture modes (standard-lens and wide-angle) are integrated into a single device, then device versatility is improved, but the user interface becomes more complex and harder to navigate
Solution Approach 1:
The patent implements dynamic gesture recognition where the direction of hand rotation determines the photo capture mode transition. Rotating clockwise switches to wide-angle mode, while rotating counterclockwise switches to standard-lens mode. This dynamic gesture system provides an intuitive and easy-to-remember method for navigating between multiple photo capture modes without complex menus or buttons.

AI summary
The disclosed technology includes switching between a normal or standard-lens UI and a panoramic or wide-angle photography UI responsive to a zoom gesture. In one implementation, a user gesture corresponding to a “zoom-out” command, when received at a mobile computing device associated with a minimum zoom state, may trigger a switch from a standard lens photo capture UI to a wide-angle photography UI. In another implementation, a user gesture corresponding to a “zoom-in” command, when received at a mobile computing device associated with a nominal wide-angle state, may trigger a switch from a wide-angle photography UI to a standard lens photo capture UI.
