Barcode Scanner AR HUD Interface Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in obtaining real-time information and making selections with rugged barcode scanners that lack screens, as they struggle to operate heads-up displays (HUDs) while carrying both the scanner and an object to be scanned, especially in loud inventory environments.
Innovation Solution
Pairing handheld barcode scanners with augmented reality HUDs to display a virtual screen, where the scanner's unique identifier anchors the virtual interface, allowing users to interact with it by tilting or using triggers to make selections, enabling simultaneous operation of the scanner and HUD without a physical screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rugged barcode scanner is made without a screen to withstand extreme conditions, then the device's durability and reliability are improved, but the user's ability to obtain real-time information and make selections is worsened
Solution Approach 1:
The patent transitions the user interface from a physical 2D screen on the scanner to a virtual augmented reality display in the user's field of view, adding a spatial dimension to the interaction. The virtual screen appears to float in 3D space and can be manipulated through head movements and gestures, resolving the contradiction by providing full interface functionality without requiring a physical screen on the rugged device.
Solution Approach 2:
The patent introduces an augmented reality headset as an intermediary device that receives data from the rugged barcode scanner and presents it through a virtual interface. This mediator handles all user interaction tasks, allowing the scanner itself to remain screenless and durable while the headset provides comprehensive display and control capabilities.
2Loss of information
If a HUD is used to display information, then real-time information access is improved, but the user's ability to operate the scanner and HUD simultaneously is worsened due to hands being full
Solution Approach 1:
The patent enables the barcode scanner to interact with the augmented reality interface using its own built-in sensors. The scanner's accelerometer and gyroscope detect device orientation and movement, allowing the scanner itself to navigate the virtual interface, make selections, and control the HUD display without requiring manual input from the user's hands.
Solution Approach 2:
The patent replaces manual mechanical interaction (touchscreen gestures, button presses) with automated sensor-based control. The scanner uses its motion sensors to automatically manipulate the virtual interface elements, substituting the need for hands-on operation with an automated system that responds to the scanner's physical movements in space.
3Ease of operation
If voice input controls are used for the HUD, then hands-free operation is improved, but the system's reliability is worsened in loud inventory environments
Solution Approach 1:
The patent replaces acoustic input methods (voice recognition) with mechanical sensor input. The scanner's accelerometer and gyroscope detect precise physical movements and orientations, providing reliable control signals that are不受affected by ambient noise levels in the inventory environment.
Solution Approach 2:
The patent changes the control input parameter from acoustic signals (voice) to mechanical motion signals (acceleration, orientation). This parameter change makes the control system immune to acoustic interference while maintaining hands-free operation, as the scanner's built-in motion sensors can detect device movements regardless of environmental noise.
Data Source
AI summary
A system configured to display an augmented-reality user interface for a barcode reader using a heads-up display assembly is provided. An augmented reality adapter having a camera and a presentation generator is configured to identify a unique identifier associated with a handheld barcode reader and provide an augmented reality display based on data captured by the handheld barcode reader. The presentation generator may position the augmented reality display based on a location of the unique identifier within the field of view (FOV) of the camera.
