Jack and Ellen are a middle-aged couple with two sons, Pit (3) and Lucy (8). They decided to spend this Saturday at their city's Science Museum, where they haven't been before. During the week, they have been using their home desktop to visit the museum website and know its location, opening hours and admission fees.
As they arrive to the museum on Saturday morning, they can see some panels inviting visitors to use the iPhone as a guide. Ellen types the indicated URL on her iPhone and enters to the museum's guide. It's different from the website they visited yesterday, but they recognize the same look.
Their plan is to take a general look of about an hour, then go to the kids' area (they saw it yesterday on the museum's website) and then go to lunch. After lunch, if kids are not tired, they could do a random walk to discover new things without having in mind a pre-established order. They know that it's not always possible to maintain plans when kids are so young.
On the Iphone, Ellen can select "Guided tours", "Map" or "General information". Ellen decides to have a look at the guided tours. She orders the list by duration and sees two different tours of 1 hour. One of them has been created by another visitor but she prefers the one made by the museum staff, so she selects it.
A zoomable map of the museum appears, with their location automatically displayed, and a path that indicates where they should go now. At the bottom of the map, they can see brief textual indications. As they walk by the museum, their location is constantly updated and the path changes from green to red when they separate from it.
When they are in front of an exhibition's item, an info option appears on one corner of the screen. They can press this option to see the piece's information. On the information card they can take photographs, record their voice, write commentaries, favourite or tag it, or send it to some friend. In some cases, they can even save activities to do at home. The first time they try to do one of these actions, they are asked for a username. Once they've entered it, they haven't been requested again.
They've finished the guided visit and kids want to play, so Ellen presses the Map option to know where the kids' area is. She can zoom in the map until she finds it or enter a keyword in an text entry field, but she prefers to use a combo box with the list of services of the museum. When she selects "kids' area", map becomes tridimensional to represent the 5 floors of the museum, and they can see that they should lift up two floors. They click on the "Show me the path" option, and a path on the map guides them until the kids' area.
Half an hour later, they repeat the same action to go to the museum's restaurant. During the lunch, they go throughsome of the things they have recorded. Their morning visit has been saved, so they can remember the best moments. Pit wants to record a new commentary to one of the objects that where on the tour, and so he does.
On the afternoon they spend one more hour walking randomly by the museum. As at the morning visit, every time they are next to an object, the info option appears. Non intrusive alerts appear also when lifts or other services are near, indicating their direction.
When they're about to leave the museum, they use a museum's service that takes them a photo and sends it to their iPhone. They email this image with a message and a fun background to two friends.
On the way home, they're looking forward to reach home and have a new look to their day at the museum from their desktop.
