Wireless Communication Apparatus Dynamic Button Sizing for Remote Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies in digital cameras, such as Bluetooth Low Energy, have insufficient communication speed for transmitting live view images, making it difficult for users to capture images remotely without looking at the camera's screen, leading to potential missed opportunities due to inaccurate button touches.
Innovation Solution
A communication apparatus with a control unit that allows for remote control of an imaging device through both high-speed and low-speed wireless communication modes, featuring a display unit that adjusts button sizes and detection for touch operations, enabling users to capture images more accurately even without looking at the mobile phone screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Bluetooth Low Energy wireless communication is used for remote control, then power consumption is reduced and compatibility is improved, but communication speed becomes insufficient for transmitting live view images
Solution Approach 1:
The system dynamically changes communication parameters by switching between two distinct communication modes: a first mode using high-speed wireless communication (e.g., Wi-Fi) for transmitting live view images, and a second mode using low-speed wireless communication (e.g., Bluetooth Low Energy) for basic remote control operations. This parameter change allows the system to optimize between power consumption and communication speed based on operational requirements.
2Ease of operation
If shutter button size is increased for easier touching, then ease of operation is improved, but display space for other controls is reduced
Solution Approach 1:
The shutter button display size is made dynamic rather than static. The system automatically adjusts the shutter button size based on the detected operating mode: displaying a first (larger) size when in low-speed communication mode to facilitate accurate touching without looking, and a second (smaller) size when in high-speed communication mode where live view feedback is available. This dynamic adjustment resolves the contradiction between ease of operation and display space utilization.
3Measurement precision
If user looks at camera screen to ensure accurate shutter pressing, then imaging precision is improved, but ease of operation is reduced
Solution Approach 1:
The system introduces an intermediary mechanism in the form of a magnified shutter button display on the mobile phone screen. This intermediary visual aid allows users to accurately locate and press the shutter button without needing to look at the camera's own screen, thereby maintaining imaging precision while preserving the ease of remote operation. The magnified display acts as a mediator between the user's finger and the actual shutter trigger.
