Digital Device Gesture Mode Switching for Wearable Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices, due to their small size and limited screen space, face challenges in providing an effective field of view and inputting touch commands, while digital devices with larger screens offer better usability but reduced portability and accessibility, especially in responding to events like calls and messages.
Innovation Solution
A digital device and external device system that detects gestures and events to switch between modes, allowing the digital device to provide modes corresponding to events and the external device to adjust its mode based on received signals and user interactions, thereby optimizing usability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device is used to ensure portability and accessibility, then the device can be worn on the body and carried conveniently, but the screen size becomes small making it difficult to secure a field of view and input touch commands
Solution Approach 1:
The patent combines the wearable device and digital device into a coordinated system where the digital device serves as an extended display and input interface. The devices are merged functionally through wireless communication, allowing the digital device to handle tasks requiring large screen interaction while the wearable device maintains portability.
Solution Approach 2:
The system implements multi-functionality by enabling both devices to perform different roles based on the situation. The wearable device handles notifications and basic interactions, while the digital device provides comprehensive display and input capabilities, creating a universal solution that adapts to different usage scenarios.
2Area of moving object
If a digital device with large screen size is used to secure field of view and input capability, then usability is improved, but portability and accessibility are reduced requiring pockets or bags
Solution Approach 1:
The system segments the functions between two devices: the wearable device handles portability and basic notifications, while the digital device handles display and input tasks. This segmentation allows each device to be optimized for its specific role, with the wearable device remaining small and portable while the digital device provides large screen capabilities when needed.
3Adaptability or versatility
If mode switching is implemented between devices to optimize usability, then the system can adapt to different events and scenarios, but device complexity and control mechanisms increase
Solution Approach 1:
The system uses feedback mechanisms where devices automatically detect events (calls, messages, gestures) and switch modes based on the detected context. The gesture sensor unit detects user gestures and provides feedback to the processor, which then automatically switches modes without requiring complex manual control from the user.
Solution Approach 2:
The mode switching system operates autonomously by detecting events and gestures, then automatically switching between devices and modes without user intervention. The system serves itself by managing the complexity of mode transitions internally while presenting a simple user experience.

AI summary
Discussed are a digital device and a control method thereof. The digital device includes a communication unit configured to transmit/receive a signal with an external device; a gesture sensor unit configured to sense a gesture with respect to the digital device; and a processor configured to control the communication unit and the gesture sensor unit, wherein the processor is further configured to: provide a first mode corresponding to a first event when occurrence of the first event is detected; transmit a first signal, commanding provision of a second mode corresponding to a second event, to the external device when occurrence of the second event is detected during provision of the first mode; and switch from the first mode to the second mode when detecting a first gesture with respect to the digital device after transmission of the first signal.
