Proximity Detection for Map Service Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map applications on portable devices require users to perform additional operations to access service information for objects displayed on a map, such as event or reservation details, which complicates user interaction and reduces efficiency.
Innovation Solution
A portable terminal and information display control system that detects proximity of a physical object to the screen, requests and displays additional information for objects on the map without requiring direct contact, by utilizing a proximity detection unit, an information request unit, and a display control unit in conjunction with a server device that stores and delivers relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users perform touch operations to access service information for objects on a map, then additional information can be obtained, but user operability is reduced and time is consumed
Solution Approach 1:
The system performs preliminary action by detecting the proximity of a physical object to the screen and automatically displaying additional service information before the user performs any touch operation. The proximity detection unit detects when an object approaches, and the display control unit proactively shows the information popup, eliminating the need for subsequent touch operations to access the information.
2Loss of information
If users perform touch operations to access service information for objects on a map, then additional information can be obtained, but time is consumed
Solution Approach 1:
The system performs preliminary action by detecting the proximity of a physical object to the screen and automatically displaying additional service information before the user performs any touch operation. The proximity detection unit detects when an object approaches, and the display control unit proactively shows the information popup, eliminating the need for subsequent touch operations to access the information.
3Ease of operation
If proximity detection is used to display additional information, then user operability is improved, but device complexity increases
Solution Approach 1:
The system uses an intermediary approach by introducing a proximity detection unit as a mediator between the user and the map application. This intermediary component detects the presence and position of physical objects near the screen and triggers appropriate display actions, bridging the gap between user intent and information delivery without requiring direct screen contact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances user operability by allowing additional information to be displayed near objects on a map when detected by proximity, reducing the need for users to perform additional touch operations to access service details.
Implementation Method 1
a touch panel capable of detecting the proximity of a physical object (for example, the user's finger or a stylus pen) is mounted
Implementation Method 2
a touch panel capable of detecting the proximity of a physical object

AI summary
A portable terminal is a portable terminal which displays delivered content on a screen, and includes a proximity detection unit that detects proximity of a physical object to the screen and outputs a proximity detection signal, an information request unit that requests additional information for an object of content that is displayed at a proximity corresponding position which is a position on the screen corresponding to the physical object of which the proximity is detected, based on the proximity detection signal, and a display control unit that displays additional information for an object of content delivered in response to a request from the information request unit, in the vicinity of the proximity corresponding position of the screen.
