Ground Projection Navigation for Personal Transport Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for renting personal transport devices, such as scooters, do not provide convenient mechanisms for users to determine tourist sites or receive directions to those sites, making it difficult for users to navigate while riding, especially without needing to focus on a display screen.
Innovation Solution
A system and method that includes a projector on the personal transport device to project navigation directions onto the ground surface, allowing users to select destinations using various input mechanisms like grip sensors, voice commands, or arm signals, enabling guided navigation without requiring users to touch a screen or focus on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users rely on cellphone or mobile device for navigation, then navigation functionality is provided, but user safety and convenience deteriorate due to difficulty in managing the device while riding
Solution Approach 1:
The navigation interface is projected from a vertical screen onto the horizontal ground surface, changing the dimension of interaction. Users view directions on the ground in front of them rather than looking at a screen, eliminating the need to hold or touch a mobile device while riding.
Solution Approach 2:
The projector mounted on the personal transport device serves as an intermediary between the navigation system and the user. It projects directional information directly onto the ground surface, providing navigation guidance without requiring the user to interact with a mobile device.
2Loss of information
If a display screen is used for navigation, then directions are provided, but user convenience worsens due to requiring focus on the screen while riding
Solution Approach 1:
The navigation information is projected onto the ground surface in the user's forward field of view rather than requiring focus on a screen. This dimensional change allows users to perceive directions naturally while maintaining awareness of their surroundings.
Solution Approach 2:
The ground surface serves as the display medium, eliminating the need for a separate screen. The projection adapts to the environment by using the existing ground surface, providing navigation information that integrates with the user's natural viewing direction.
3Adaptability or versatility
If conventional rental methods are used, then personal transport devices are provided, but navigation functionality deteriorates due to lack of integrated guidance mechanisms
Solution Approach 1:
The navigation system is merged with the personal transport device by mounting a projector on the device itself. This integration combines the transport function with navigation guidance, eliminating the need for separate mobile device management.
Solution Approach 2:
The personal transport device is enhanced with multi-functionality by incorporating a projector that provides navigation guidance. The device now serves both as a transport mechanism and as a navigation system, improving overall versatility.
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
Enables users to receive guided navigation to selected destinations in a geographic area, enhancing safety and convenience by projecting directions directly in front of the user, allowing hands-free navigation and selection between multiple destinations.
Implementation Method 1
projecting directions to one or more of the predetermined destinations on a ground surface located in front of the personal transport device
Data Source
AI summary
A method for providing guided navigation for personal transport devices is described. In one embodiment, the method includes providing a list of predetermined destinations associated with a geographic area, projecting directions to one or more of the destinations on a ground surface located in front of a personal transport device, and providing an option to a user of the personal transport device to select between at least two different destinations. A direction associated with each destination of the at least two destinations may be projected on the ground surface located in front of the personal transport device. The method also includes receiving an input from the user indicating a selection of one of the at least two different destinations and projecting directions to the selected destination on the ground surface located in front of the personal transport device to guide the user to the selected destination.
