Problem & Proposed Solution• Finding parking in a congested area

can often be a major problem:• Stress & Frustration• Waste of gasoline & production of

CO2 emissions• Loss of money and time.

• Our solution is an application that helps drivers find parking spaces before reaching their destination.

Contextual InquiryContribution to design:

• Parking plan is often based on guessing

• Previous parking decisions in a particular area greatly influence future decisions.

• Preferences for parking varies by individual.


Experience Sampling Method

Contribution to design:• Customers can find parking

relatively easily for familiar and recurrent destinations.

• Parking concerns (availability, location safety, etc.) arise for more foreign locations.


Primary Tasks of Solution• Determine overall parking availability for an area

Medium Task Difficulty

• Find parking near a destination and get directionsHard Task Difficulty

• Mark current location using GPS as a saved parking locationEasy Task Difficulty

What it does:• Functionality based around three primary tasks, as mentioned before.

• Some other functionality also included, such as map display modes, ‘Find Car’ option, etc.

How it works:• Created with Adobe Photoshop and Adobe Dreamweaver with Image

Mapping.

• Executed through any standard web browser.

What is missing:• Panning and zooming capabilities for interactive map.

• Current location, destination, and search criteria are fixed values.

• Database of actual garage information, availability, etc (backend)
