Using Prototypes in Design

Generating Storyboards from Scenarios

• A storyboard represents a sequence of actions or events that the user and the system go through to achieve a task.
• A scenario is one story about how a product may be used to achieve a task.
• By: Break the scenario into a series of steps which focus on interaction, and then create 1 scene in the storyboard for each step.

Steps in the travel organizer scenario

1. The Thompson family gathers around the organizer and enters a set of initial requirements.
2. The system’s initial suggestion is that they consider a flotilla holiday but James and Ethan aren't happy.
3. The travel organizer shows them some descriptions of the holiday written by young people.
4. The system asks for various further details.
5. The system confirms that there are places in the Mediterranean.
6. The travel organizer prints out a summary.

Designers are forces to think on:

First:

• Input/output devices
• Where the organizer will be
• Don’t have to decide but are force to think about using such as touch screen or screen
• Screen, helps to explore design decision and alternatives

Second:

• How can the interaction be design for all the family?
• Will they sit or stand?
• How confidential should be?
• What kind of documentation?

Generating card-based prototype from use cases

• Value of card-based prototype – screen or screen elements can be manipulated and moved around in order to simulate interaction
• Storyboard focusing on screen > card-based prototype / can generate directly from use case output.
• The use of case for the visa requirements using the travel organizer:

The system display options for investigating visa and vaccination requirements.

The user chooses the option to find out about visa requirements.

The system prompts user for the name of the destination country.

The user enters the country’s name.

The system checks that the country is valid.

The system prompts the user for her nationality.

The system checks the visa requirements of the entered country for a passport holder of her nationality.

The system displays the visa requirements.

The system displays the option to print out the visa requirement.

The user chooses to print the requirements.
