The Missing Link: Blockchain for Digital Credential Tracking & Reporting

Watch the presentation video​​​

Blockchain based digital credentialing will be introduced, and demonstrated how it can be used to track the progress of students in career and technical education (CTE). In addition to tracking progress in CTE, blockchain based digital credentialing also has the potential to track standards and help close a gap in school-to-career transition through possible alignment with Department of Labor Apprenticeship Programs. The information in this presentation will be targeted towards those in workforce development, industry training, and CTE. In addition to the requirements for a recorded video presentation, I plan on using the additional time to screen share the presentation and engage in questions and answers with the audience. At the conclusion of the presentation and Q&A session, the audience will have a better understanding of what blockchain is, how it can be used in education and workforce development to track progress, verify authenticity, and be used to target training. Additionally, we will go over benefits such as alignment of standards and authenticity in the credentialing aspect, and demonstrate how this is beneficial to students and future employers through choice, empowerment, and can lead the way towards more equitable outcomes.

The prototype was developed for a pressing plant where personnel need to assess the quality of large pressed parts. This could be, for instance, to check if holes are punched correctly or if special markings are present at the right positions. The prototype was developed on Hololens 2 using Unity 3D.
Challenge: Personnel inspecting the parts for anomalies take 15-20 minutes. 2D reference material slows down the process of inspection as the user needs to go back and forth to understand where to look and check for intricate anomalies. This process is error-prone, especially when there are too many items to be checked in succession on large parts.
Solution: The AR application reduces inspection time to under 5 minutes. The exact overlaying of a 3D model of the pressed part on the physical object, enables identifiers to be positioned over specific areas of interest. This enables the personnel to focus very quickly on check points, rather than remember or refer to external information. This is then followed by an instructional sequence which helps in validating the precision and quality. The app also provides for media shown directly at check points which facilitate reference based checks. With simple and intuitive gestures, the anomalies can be registered, consequently removing the need to “learn” how to use the app. Protocoling of the results, by taking photos/videos or simple UI features, is done directly through the app communicating with a server. The added feature of user management allows for storing of protocols based on the user currently logged in. This can then be revisited by the same or another user.
As part of future research, we aim to optimize the application to include tracking, modification and automation of content within the app.
