Web-Ticket hits a real world issue of managing multiple accounts securely. By suggesting physical tokens, Web Ticket aims at decreasing the cognitive overload for people who have hard time remembering their passwords. In this project, I worked with Eiji Hayashi and Professor Jason Hong (Carnegie Mellon’s HCI program) to develop interfaces and interactions for this web account management system. This project concept is promising for undermined user segments such as elderly.
This was written up in a CHI 2012 article, please see that paper for all the details and research outcomes.
WebTicket, a low cost, easy-to-use and reliable web account management system that uses “tickets”, which are tokens that display a two-dimensional barcode. Users can log into accounts by presenting the barcodes to web cameras connected to computers.
It is an interactive system consisting of a web-browser extension, tokens (either printed or on a mobile device), a webcam, and a computer. When creating an account using our system, a user can print a paper-based token (ticket) with a 2D barcode containing a login script. This login script includes the URL of a web site, a user ID, and an encrypted password. T
o log into an account, a user can show the ticket to a webcam attached to their computer. WebTicket scans the 2D barcode, opens the website in a browser, and logs into the account, obviating the need for users to enter in user names and passwords. Below are examples from the project interfaces.
