This design is a data visualization application. Essentially, for ever purchase, you type in the amount spet, and the phone will automatically record the current time and location. A map will be shown, together with the current time, to let the user know where the app thinks he is and what time it is. By clicking on the map, the the user can override the apps location-guess if it is incorrect, inaccurate or outdated.

Clearly it’s Jaden’sdinner outings which are making up most of his spending, given the huge peaks on Satuday night and Sunday nights! Also suddenly apparent is the spending peak that happens every saturday night past midnight, obviously all the nightclubs that he has been going to have been a drain on his pocket!

Wiki MarkupWith that information in mind, Jaden wants to know which clubs he is spending all his money in on saturday nights (he goes to several). He right pinches to zoom in on the time period he wants (12mn \ -> 6am Sunday morning) and selects the \ [Map\] from the android menu. This brings up a map of his spending hotspots for that time period, with expenditure automatically consolidated based on physics proximity:


The map view is meant to display to the user the hot spots of his expenditure. Thus it displays a Google Map of the area which any transactions within a stipulated time period (generally the period that is visible on the time-series view from which the map view originated).

The size of the spot representing each cluster of expenditure represents the net expenditure at that location. Clicking on a spot will bring up the detailed history view for that location.

In terms of learnability, the size-represents-expense relationship should be relatively simple for users to understand, given that such visualizations are often seen elsewhere in infographics.

Efficiency is also maintained by the fact that the user can at a glance see qualitatively all the information he needs, and can easily drill down into more detail if necessary by tapping an inividual hotspot.

...

Which brings up a historical listing of all the spending Jaden has made in this position. Pretty handy!

Analysis

Overall, the learnability of this design is excellent. This is not because of special cues or metaphors that it is using, but is simply from using familiar metaphors (maps, time-series, dragging, zooming) in a new context. The purpose of this is to allow the user to
