Solution Overview
Problem
Current mobile terminals, especially wearable watch-type devices, lack efficient methods for remote control and sharing of photographs taken by connected photography devices, limiting user convenience and functionality.
Innovation Solution
A watch-type mobile terminal equipped with a wireless communication unit, display unit, and controller that allows users to receive and decode preview images, transmit remote photograph commands, and share photos with other terminals, utilizing gestures and predefined inputs for control and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a wearable mobile terminal is used for remote control of photographing device, then portability is improved, but control precision and user interaction quality deteriorate
Solution Approach 1:
The wearable mobile terminal serves as an intermediary device between the user and the photographing device. It transmits control commands (shutter release, zoom, focus) from the user to the photographing device via wireless communication, enabling remote control while maintaining portability. The terminal acts as a mediator that bridges the gap between limited wearable interface capabilities and the need for precise photographing control.
Solution Approach 2:
The wearable mobile terminal performs multiple functions: it serves as a remote control for the photographing device, displays preview images, transmits captured images, and provides user interface for control operations. This multi-functionality compensates for the limited size and interface capabilities of wearable devices, allowing them to perform complex photographing control tasks that would otherwise require a larger device.
2Loss of information
If preview image data is transmitted to wearable terminal, then remote viewing capability is improved, but power consumption increases
Solution Approach 1:
The wearable mobile terminal receives and displays preview image data from the photographing device, enabling the user to view the preview remotely on the wearable device. This partial transmission of image data to the wearable terminal provides sufficient viewing capability for composition and framing, while avoiding the excessive action of full-resolution continuous streaming that would drain power quickly.
3Ease of operation
If remote photograph command is transmitted from wearable terminal, then remote control capability is improved, but control reliability deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the wearable terminal receives confirmation signals from the photographing device after transmitting control commands. The terminal displays feedback information such as successful shutter release, image capture status, and transmission confirmation. This feedback loop ensures that control commands are reliably executed and provides the user with real-time status information, compensating for the potential unreliability of wireless remote control.

AI summary
Disclosed are a mobile terminal of a watch type and controlling method thereof, by which a photographing device can be remotely controlled. The present invention includes a wireless communication unit configured to communicate with a photographing device, a display unit configured to display a preview image inputted through a camera of the photographing device before a photo is photographed through the photographing device, and a controller, if a preset user input is received while the preview image is outputted, controlling a remote photograph command to be transmitted to enable the photo to be photographed through the photographing device.
