Wireless Device Search Display Using Direction-Based Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively display search results of electronic devices located within a predetermined range based on their direction relative to the user, leading to improper device selection.
Innovation Solution
An information processing device that includes a wireless communication unit for short-range communication with electronic devices, a search result acquisition unit, a direction information acquisition unit, and a control unit to determine if the device is within a predetermined direction, enabling display processing to show only relevant devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all electronic devices found by wireless search are displayed, then the user can see all available devices, but devices outside the user's field of view or on different levels are also displayed causing confusion
Solution Approach 1:
The patent applies local quality by differentiating the display treatment based on device location. Devices within the predetermined direction range are displayed with full information, while devices outside the range are displayed with reduced information or differently marked, allowing users to distinguish between nearby and distant devices easily
Solution Approach 2:
The patent segments the display into different sections: one for devices within the predetermined direction (field of view) and another for devices outside this direction. This segmentation helps users quickly identify which devices are accessible versus which require movement or different positioning
2Measurement precision
If direction information acquisition is added to filter devices by location, then device selection accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses direction information as an intermediary parameter to bridge the gap between raw wireless search results and meaningful device selection. By introducing direction data from the direction information acquisition unit, the system can filter and prioritize devices without requiring complete redesign of the search mechanism
Solution Approach 2:
The wireless communication unit performs multiple functions: both standard wireless searching for device discovery and short-range wireless communication for direction information acquisition. This multi-functionality reduces the need for separate dedicated hardware components

AI summary
An information processing device wirelessly communicates with an electronic device via a wireless communication unit and includes a search result acquisition unit, a direction information acquisition unit, and a controller. The search result acquisition unit acquires information of a search result about the electronic device by a search via the wireless communication unit. The direction information acquisition unit acquires direction information representing a direction in which the electronic device exists, by short-range wireless communication with the electronic device via the wireless communication unit. The controller makes a determination about whether the electronic device found by the search is located within a range in a predetermined direction or not, based on the information of the search result and the direction information, and executes display processing of displaying a screen relating to the electronic device that is a target of the determination.
