Wearable Device Vehicle Identification via Target Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for hailing taxis, whether by hand signal or location-based systems, lack efficiency in ensuring the user can accurately identify the correct ride-share vehicle, especially in scenarios involving autonomous vehicles.
Innovation Solution
A communication system comprising a vehicle with a wireless transceiver system and an indicator, and a wearable device that receives a target beam from the vehicle, allowing the user to orient towards the vehicle and confirm its identity through a matching light pattern, facilitating accurate vehicle recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is provided to a taxi driver via a handheld mobile device, then the driver can navigate to the user's location, but the user cannot accurately verify that the arriving vehicle is the correct ride-share vehicle
Solution Approach 1:
The patent introduces a wearable device as an intermediary between the user and the vehicle communication system. This device receives targeted communications from the vehicle's transceiver system and displays verification information (such as matching light patterns or visual cues) to help the user accurately identify the correct vehicle without requiring complex manual verification procedures
Solution Approach 2:
The patent replaces manual verification methods (visual inspection of vehicle appearance, comparing license plates, etc.) with an automated optical/electronic verification system. The vehicle's transceiver system communicates with the user's wearable device through targeted signals, and the user verifies vehicle identity through matching visual patterns displayed on the wearable device, eliminating the need for manual mechanical verification
2Reliability
If the driver passes by the user without stopping, then the driver may be unavailable or unable to taxi the user, but the user loses time waiting for a available vehicle
Solution Approach 1:
The patent implements a feedback mechanism where the user's wearable device continuously monitors for targeted communications from nearby vehicles. When a vehicle approaches or passes by, the transceiver system sends targeted signals to the wearable device, providing immediate feedback to the user about available ride options without requiring the user to actively search or wait
Solution Approach 2:
The patent enables preliminary vehicle identification and verification before the vehicle arrives at the user's location. The wearable device can detect and display verification information from approaching vehicles in advance, allowing the user to prepare for the arrival and reduce waiting time by having verification information ready before the vehicle stops
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 efficient and accurate identification of the ride-share vehicle, enhancing user experience by ensuring the correct vehicle is recognized, even in autonomous modes, through line-of-sight communication and matching visual cues.
Implementation Method 1
receiving, at a first transceiver element of a wearable device, a target beam from a ride-share vehicle
Implementation Method 2
the indication includes a light pattern that matches a light pattern emitted from the vehicle
Data Source
AI summary
A system that includes a wearable device, and a method of using the system, including: receiving, at a first transceiver element of a wearable device, a target beam from a ride-share vehicle, the element having a first axis of reception; and when the first axis is oriented toward the beam, providing an indication, via the device, to a user thereof.
