Result
The resulting system is an extension of Gmail that better allows people to plan casual events with their friends, whether they are Gmail users or not. For a given event, friends are able to gradually define the different elements of the event: Who (invited members), What (activity), Where (location), When (date and time), and Don't Forget (supplementary critical information). The creator of the event will have control over setting these fields, but essentially all participants collaboratively plan the event through the Discussion Area (and by using Suggestions).
The Fiesta system supports communication through several different modalities in order to adapt to the varied needs of users. They can receive communication through Gmail/external e-mail, mobile phone, instant-messaging client, or pop-up messages on their computer. They can also receive alerts and reminders about the event via these different modalities.
The Fiesta system also allows events to be added to a digital or online calendar once the user sets a date for the event. Additionally, the creator of the event may use Google Maps to provide an address for the event's location, allowing participants to easily obtain directions.
Finally, to support users while they are physically on their way to the event, the system includes mobile access which allows people to get directions to an event via their cellphones or to text-message others involved in the event. This last feature can be very helpful when needing to notify friends of last-minute changes.
