Directional Infrared Interface for Wireless Connection Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when attempting to establish a wireless connection between a portable terminal and a distant device, such as a television, as they must stand up to touch or identify the device, which is burdensome.
Innovation Solution
A wireless communication device equipped with a directional infrared interface that sends signals to allow users to select a connection target without physically moving, using a directional signal to specify the target device and establish a wireless connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user touches a distant device to establish a wireless connection, then the connection can be established accurately, but the user must physically move to the device which increases user burden
Solution Approach 1:
The patent replaces the mechanical touch operation with an optical signaling system. The portable terminal emits infrared directional signals that can be detected by distant devices, allowing connection target specification without physical contact or movement to the device location.
Solution Approach 2:
The patent introduces infrared directional signals as an intermediary between the user's selection intent and the target device. The signals act as a mediator that carries identification information from the portable terminal to the distant device, enabling accurate connection establishment without direct user interaction with the device.
2Adaptability or versatility
If multiple connection target candidates exist, then the user has more options, but it becomes difficult to identify and select the necessary target
Solution Approach 1:
The patent uses visual differentiation through display highlights and indicators to help users identify the currently targeted device among multiple candidates. The display device shows different visual states for different connection targets, making it easy to distinguish and select the desired device.
Solution Approach 2:
The system provides real-time feedback by displaying which device is currently being targeted when the infrared pointer points at it. This feedback mechanism helps users confirm their selection intent and adjust the pointing direction accordingly, simplifying the selection process among multiple candidates.
