Making Elections Secure, Accessible and Usable

Prime III & inLine Ticketing

The Computing for Social Good Lab invented Prime III, an open source accessible voting technology. To the lab's knowledge, it was the first voting system to implement universal design. Prime III is also the only open source voting technology created by a university research lab that has been adopted and used in Federal, State and Local elections, and many modern ballot marking devices (BMD) were modeled after it.

The lab also invented the inLine Ticketing System, which provides social distancing during voting and other contexts by forming a virtual line. The team is also working on absentee voting technologies to ensure all absentee ballots are counted, and on voter verification.

Making Voting Technologies Transparent

Transparent Voting Machine

The transparent voting machine prototype is powered by Prime III. This ballot marking device demonstrates a patented transparent interactive printing interface that lets voters see their selections and approve them upon printing.

Making Algorithms Fair and Unbiased

Applications Quest

Dr. Gilbert invented Applications Quest, a patented technology that helps admissions and hiring officials manage applicant pools when there are more qualified applicants than available slots. It uses a data mining algorithm to make holistic comparisons of applications, and is also being used to reduce bias in machine learning algorithms.

Making Traffic Stops Safe

Virtual Traffic Stop

The Computing for Social Good Lab invented the Virtual Traffic Stop to address conflicts during traffic stops. It uses mobile phones to connect drivers with law enforcement and a third party to reduce tensions, a de-escalation mechanism that can keep both law enforcement and drivers safe.
