For the redesign of the Palm Pilot, my group and I gathered data from several different HCI methods to propose changes to improve the use of the Palm. We modeled a contextual inquiry, conducted our own cognitive walkthroughs and heuristic evaluations, and then analyzed a think aloud.

The redesigns we proposed were driven by the data we gathered and later analyzed. Below are the major changes we suggested:

1) Include a toolbar. At the bottom of the screen, we will implememtn a toolbar to allow users to quickly switch between applications. This will also allow them to also know which applications are open so that they do not need to re-open the same application.

2) Easier synchronization of calendars for meetings. This function allows two users to use the infrared beam to send their calendar to the other person in order to find a mutual free time for a meeting.

3) Email to calendar connection. If the user receives an email with a meeting time, the Palm will allow him to immediately put that meeting into his calendar with all the information already preset.
