Presentation Scanner Feedback for Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Presentation scanners face challenges in helping users position objects and code indicia within the scanning volume, as they often require manual alignment and lack effective feedback mechanisms, making it difficult for users to accurately place the object and code indicia for scanning.
Innovation Solution
Incorporating a user interface with visual, audio, and vibration devices that provide sensory feedback to indicate the relative position of the object and code indicia within the scanning volume, using sensors to detect object presence and process images to identify the code indicia's location, and activating sensory indicators to guide the user for proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a presentation scanner is used without manual alignment assistance, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in positioning the object and code indicia
Solution Approach 1:
The patent implements feedback mechanisms through sensors that detect object presence and code indicia position, providing real-time information to the user interface to guide proper positioning. The system monitors the scanning volume and provides feedback about the relative position of code indicia, enabling users to accurately place objects without complex manual alignment procedures.
Solution Approach 2:
The patent introduces an intermediary user interface layer between the scanning device and the user. This interface includes visual indicators, audio signals, and vibration feedback that mediate the positioning process, translating complex positioning requirements into simple user-friendly cues that guide the user to correctly position the object and code indicia.
2Ease of operation
If multiple sensors and sensory indicator devices are added to provide positioning feedback, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent segments the feedback system into distinct functional components: object presence detection sensors, code indicia position detection sensors, and sensory indicator devices. Each component performs a specific function and can be independently optimized or configured, allowing the system to provide comprehensive positioning feedback while maintaining manageable complexity through modular design.

AI summary
A method of scanning an object may include determining that an object is proximately positioned relative to a scanning volume of a presentation scanner in response to receiving at least one object presence signal prior to scanning a code indicia positioned on the object. At least one object sensory indicator device may be activated in response to determining that the object is proximately positioned relative to the scanning volume so as to indicate that the object is proximate to the scanning volume to a user. A second level of detection and location feedback may be provided for code indicia within the scanning volume.
