  42. Multi-Mouse for Education Problem: PCs in emerging-market schools are used in a one-to-many fashion. Solution:Multiply the value of PCs by allowing multiple USB mice to be plugged into a PC, with each mouse having a cursor on-screen with a different color. Children grasp the concept immediately and show greater engagement. Papers presented at WWW2006 & ICTD2006. Currently working on software SDK to be distributed online, as well as studies to test educational value of multi-mouse paradigm. Before After More info: udaip@microsoft.com

  43. Text-Free User Interfaces Job search for domestic laborers Problem: Can a UI be developed to allow an illiterate, first-time PC user to access information he/she needs without any assistance or prompting? Solution: Liberal use of semi-abstracted cartoons; voice feedback; introductory video for broad context Subjects who initially don’t want to touch the PC become engaged users; subjects who can read a little bit, still prefer text-free UI. Papers presented at AACC 2005 and ICTD 2006. Currently working on an authoring tool, and testing in different domains (e.g., healthcare). More info: indranim@microsoft.com
