Navigation Device Activity Icon Display

The patent creates a visual copy of activity information by displaying activity icons directly on the navigation map at their corresponding geographic locations. Instead of showing text descriptions that require user selection and interpretation, the system projects graphical representations (icons) onto the map canvas, allowing users to immediately perceive activity locations and make selections by simply pointing or touching the icon on the map.

The patent transitions activity information from a one-dimensional text list to a two-dimensional spatial representation on the navigation map. By mapping activity icons to their geographic coordinates (latitude and longitude) and displaying them on the map canvas, the system adds spatial dimension to the information presentation, enabling users to intuitively understand activity locations and relationships without sequential text browsing.

The patent uses visual icons as graphical copies of activity information that can be directly interacted with on the map. Each activity icon represents specific activity information (such as restaurants, attractions, or points of interest) and can be selected by simple pointer or touch input, eliminating the need for complex text-based navigation and selection procedures while preserving all relevant activity details.

The patent employs different colored icons to represent different types of activities or categories of information. By using color coding and visual differentiation, the system conveys multiple layers of information (activity type, category, status) through visual attributes rather than requiring users to read and process extensive text descriptions, thereby reducing operational complexity while maintaining information richness.
