Phone Screen Map Display During Voice Call
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual-mode wireless communications devices cannot easily share and view current location information and maps of other parties during a call without terminating the call, as they lack a user interface element for route directions.
Innovation Solution
A method and device that display a map of the current location of other parties on the phone screen during a call, with an embedded user interface element to provide route directions, using GPS and data channels for concurrent location data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the call is terminated to access location information and map applications, then the user can view location information, but the call connection is lost
Solution Approach 1:
The patent merges the map application and location information display with the phone screen by integrating the map interface into the ongoing call interface. This allows the caller to view location information and maps without terminating the call, as both functions operate simultaneously within the same display interface.
Solution Approach 2:
The phone screen is designed to perform multiple functions simultaneously - maintaining the voice call connection while also displaying location information and map interfaces. The system enables the screen to serve both communication and navigation purposes without requiring separate applications or call termination.
2Loss of information
If a separate map application is launched to view location information, then location data can be accessed, but the user interface becomes more complex
Solution Approach 1:
The map application functionality is merged into the phone screen interface, eliminating the need for separate map applications. The location information and map display are integrated directly into the call interface, reducing the number of separate applications the user must launch and manage.
3Adaptability or versatility
If route directions are added to the map display, then navigation functionality is improved, but the phone screen space is reduced
Solution Approach 1:
The navigation information is segmented into different display areas within the phone screen. Route directions, location markers, and call information are divided into distinct segments that can be displayed simultaneously without overlapping, optimizing the use of available screen space while providing comprehensive navigation functionality.

AI summary
A wireless communications device includes a radiofrequency transceiver having a wireless voice channel for transmitting and receiving voice communications and a separate wireless data channel for concurrently transmitting and receiving other data. The wireless communications device also includes a memory operatively connected to a processor for processing current location data received over the data channel from another communications device with which the wireless communications device is simultaneously communicating on the voice channel. The wireless communications further includes a display for displaying a phone screen during a voice call, the phone screen presenting call-related information. A map is displayed on the phone screen during the voice call, the map presenting a location current of the other communications device based on the current location data received over the data channel. Optionally, the map can also show the current location of the wireless communications device.
