Direction-Based Point-of-Interest Services on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location-based services on mobile devices provide static and limited navigation and search experiences, relying solely on device location without considering directional information or dynamic updates, leading to a lack of user-tailored experiences.
Innovation Solution
Incorporating positional and directional components, such as GPS and digital compasses, to enable direction-based pointing services that process both location and orientation information, allowing for dynamic updates and context-sensitive interactions with points of interest, using algorithms to define scopes of objects and provide real-time information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional location-based services use only positional information from GPS, then the system complexity remains low, but the user experience becomes static and limited
Solution Approach 1:
The patent combines positional information from GPS with directional information from digital compasses and orientation data from accelerometers into a unified location-based service system. This merging of multiple data sources enables dynamic, context-aware point-of-interest recommendations while managing system complexity through integrated processing architecture
Solution Approach 2:
The system transitions from static location-based services to dynamic services that continuously update point-of-interest information based on real-time changes in device position, orientation, and movement. The service adapts to user context by processing streaming data from sensors and dynamically filtering/recommending POIs based on current device state
2Loss of information
If the system processes only static bulk data representing endpoints, then data processing complexity is low, but the information becomes fixed in time and less useful
Solution Approach 1:
The system implements continuous data processing by continuously receiving and processing streaming positional and directional data from sensors. Instead of periodic bulk updates, the system maintains continuous awareness of device location and orientation, enabling real-time updates to point-of-interest information and maintaining information freshness throughout user interaction
Solution Approach 2:
The system incorporates feedback mechanisms where processed sensor data continuously informs service recommendations, which in turn guide further user interaction and sensor data collection. The location-based engine uses feedback from device orientation and position changes to dynamically adjust POI filtering and recommendations, creating a closed-loop system that maintains information relevance
3Adaptability or versatility
If conventional systems provide general navigation routes, then the service coverage is broad, but the user-tailored experience is lacking
Solution Approach 1:
The system applies local quality by providing customized point-of-interest recommendations specific to each user's immediate context, device orientation, and location. Instead of uniform service delivery, the system tailors POI information to the specific directional vector and positional context of each user, delivering locally-relevant information based on individual user state

AI summary
Mobile endpoints are provided that enable direction based pointing services including a positional component for receiving positional information as a function of a location of the portable electronic device, a directional component that outputs direction information as a function of an orientation of the portable electronic device and a location based engine that processes the positional information and the direction information to determine a subset of points of interest relative to the portable electronic device as a function of at least the positional information and the direction information. Devices can include compass(es), e.g., magnetic or gyroscopic, to determine a direction and GPS systems for determining location. A component for determining acceleration can also optionally be included.
