Intraoral Scanner Dynamic Feedback via Auditory Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraoral scanning devices require users to focus on a display for real-time feedback, diverting attention from the patient and increasing scanning time due to the need to monitor progress on a graphical user interface, and they lack immediate feedback on diagnostic data quality and coverage.
Innovation Solution
A computer-implemented method that generates a digital 3D representation of a dental object, compares new scan data to existing data, and provides a feedback signal to guide the user on data coverage and quality, allowing them to focus on the patient while scanning, using auditory, visual, or haptic signals to indicate areas that need re-scanning or new data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time visual feedback is provided through a display during scanning, then data coverage information is provided to the user, but the user's focus is diverted from the patient to the display
Solution Approach 1:
The patent replaces the visual display feedback mechanism with an auditory feedback mechanism using sound signals. The system generates audio feedback that provides real-time information about data coverage and scanning progress, allowing the user to maintain focus on the patient while receiving necessary feedback through sound rather than visual attention.
2Loss of information
If the user monitors the display continuously to track scanning progress, then data coverage is ensured, but scanning time increases due to slower scanner maneuvering
Solution Approach 1:
The patent implements real-time auditory feedback that continuously informs the user about scanning progress and data coverage status. The feedback signal changes based on the amount of new data acquired, providing immediate guidance that enables the user to optimize scanning speed and coverage without needing to visually monitor the display, thereby reducing scanning time while maintaining data quality.
3Ease of operation
If the user moves the scanner slower to maintain focus on the patient, then patient attention is maintained, but more scan data is acquired which increases processing time
Solution Approach 1:
The patent replaces visual display feedback with auditory feedback that provides real-time information about data acquisition progress. This allows the user to maintain focus on the patient while receiving feedback through sound, enabling them to optimize scanning speed without needing to visually track progress, thereby balancing patient attention with efficient data acquisition and processing.
4Measurement precision
If diagnostic capabilities are added to capture additional information like infrared or fluorescence images, then data quality information is obtained, but real-time feedback on diagnostic data quality is not provided
Solution Approach 1:
The patent extends the auditory feedback mechanism to provide real-time information about diagnostic data quality. The feedback signal incorporates information about the quality and coverage of diagnostic data such as infrared and fluorescence images, allowing the user to receive immediate feedback on diagnostic data adequacy without needing to visually monitor multiple displays, thereby maintaining focus on the patient while ensuring diagnostic quality.

AI summary
The present disclosure relates to a computer-implemented method for providing feedback during scanning of a dental object, comprising the steps of obtaining scan data of the dental object; generating a digital three-dimensional (3D) representation of the dental object based on the scan data; obtaining new scan data of the dental object; generating an updated digital 3D representation by adding the new scan data to the digital 3D representation; determining added information to the digital 3D representation by comparing the new scan data to at least one of the digital 3D representation(s) and/or by comparing the updated digital 3D representation to the digital 3D representation(s); and providing a feedback signal; wherein the feedback signal correlates with the added information and/or a determined overlap. The present disclosure further relates to a 3D scanner system and a handheld intraoral scanning device, configured for providing the feedback signal such as by executing the computer-implemented method.
