Portable Device Projecting Way-Points for Hands-Free Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS navigation devices require users to constantly refer to screens for navigation information, which can be inconvenient, especially in situations where hands-free operation is necessary or when navigating in different orientations and environments.
Innovation Solution
A portable device equipped with a projector, such as a micro-projector, that receives a destination location, detects the user's current location and orientation, and projects way-point information, like turn-by-turn directions, onto a nearby surface, accounting for the device's orientation and level, allowing users to navigate without screen reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If GPS navigation information is displayed on a screen, then navigation information is provided to the user, but the user must constantly refer to the screen which reduces ease of operation
Solution Approach 1:
The patent projects navigation information from a two-dimensional screen onto a three-dimensional surface in the user's environment (such as a wall or table). This dimensional transition allows the information to be viewed peripherally without requiring the user to focus on the screen, thereby improving ease of operation while maintaining information accessibility.
Solution Approach 2:
The projection system acts as an intermediary between the GPS navigation device and the user. Instead of the user directly viewing the screen, the projection mechanism translates screen information into a projected format that can be observed indirectly, reducing the need for constant screen reference while preserving navigation information delivery.
2Adaptability or versatility
If a projector is added to the portable device, then way-point information can be projected onto surfaces, but device complexity increases
Solution Approach 1:
The patent integrates a projector into a portable device that already performs GPS navigation functions. The projector adds a new display capability to an existing device, allowing it to serve multiple functions (screen display and projection display) without requiring separate dedicated equipment. This multi-functionality approach increases adaptability while managing complexity through integration.

AI summary
Navigation information may be provided. First, a destination location may be received at a portable device. Next, a current location of the portable device maybe detected. Then, at least one way-point may be calculated based on the current location and the destination location. An orientation and a level of the portable device may be determined and the at least one way-point may then be projected from the portable device.
