PINATA is a Chrome browser plug-in which detects when users are having pointing difficulties, notifies them, and offer to adapt their browsing experience. 


Research Areas

Design; AI; Accessibility. 


My Involvement

I developed the Chrome plug-in using in Javascript.

I set up a PHP server to handle storing users' pointing data and run them through a Weka classifier to identify pointing difficulty.  

I designed three different in-browser notification designs with varying degrees of interruptibility and context.
