WePatch: A System Enabling Users to Improve Bad User Interfaces on the Web

Many user interfaces on the Web are confusing for users to operate or make users more prone to mistakes, and we call such a user interface a "BADUI" (BAD User Interface). To solve these problems, we proposed WePatch, a system enables users to improve BADUIs on the Web by attaching improvement functions virtually. We implemented a prototype WePatch system as a browser extension that had functions for correcting inputted text automatically, and adding annotations and so on. Also, we experimentally compared the usability of BADUIs before and after being qualitatively improved by WePatch. The results revealed that WePatch considerably improved the usability of BADUIs.
