Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user terminal devices lack intuitive and convenient control over display devices, especially in varying user locations and conditions, limiting interactive experiences and multitasking capabilities.
Innovation Solution
A user terminal device that detects distance to a display device using sensors like BLE and activates touch and proximity inputters within a predetermined threshold, allowing for intuitive control through touch and gesture recognition, while deactivating inputs when outside the range to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch and proximity inputters are continuously activated for intuitive control, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the inputter activation state changeable based on real-time distance detection. The touch and proximity inputters are dynamically activated when the user terminal device is within the predetermined distance from the display device, and deactivated when outside this distance, allowing the system to adapt its operational state to current usage conditions
Solution Approach 2:
The patent implements feedback through continuous distance detection between the user terminal device and display device. This distance information feeds back to the controller, which automatically adjusts the activation state of inputters accordingly, creating a closed-loop control system that responds to changing spatial relationships
2Adaptability or versatility
If multiple inputters are activated for enhanced interaction, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by enabling the user terminal device to perform multiple input functions through a single integrated system. The device can operate in different modes (touch input mode and proximity input mode) depending on distance, allowing one device to serve multiple interactive purposes without requiring separate control mechanisms for each mode
3Ease of operation
If distance-based control activation is implemented, then ease of operation is improved, but measurement precision requirements increase
Solution Approach 1:
The patent applies local quality by creating distinct functional zones based on distance thresholds. The space around the display device is divided into an active zone (within predetermined distance) where inputters are activated, and an inactive zone (beyond predetermined distance) where inputters are deactivated, allowing different operational characteristics in different spatial regions

AI summary
A user terminal device (100) may include a communicator (110) configured to communicate with a display device (200), a detector (120) configured to detect a distance between the user terminal device and the display device, a plurality of inputters (130) configured to receive input of a user command, and a controller (140). The controller is configured to activate at least one of the plurality of inputters in response to a detection that the user terminal is within a predetermined distance with respect to the display device. The user terminal device may control an operation of the display device according to the distance between the user terminal device and the display device.
