Focus Area I

1. Choose search type

Choose search type both menu manipulation and voice command

Function

●Choose search type●Change search type●Cancel previous voice command

Links> Search map

Object menu items

Sequence• Make a voice command to pick “search by firm name” among three different search types.• Speak a firm name.• Change the search type to search by address.

• Advantage: The search result has very limited area because the searching area is specified.• Disadvantage: There is no feedback when unacceptable command is received

Your command is not translated correctly.Please say again

• Advantage: A user can move one menu to another menu by various commands. • Disadvantage: Because of not restricting search area, the search results can include many places that have same firm name.

Evaluation

Feedback - look and listen the response- watch the state of the navigation.

- look and listen the response

- watch the state of the navigation.

Affordances

-Navigation speaks and displays what the driver can do.

- Convey messages about possible search types.

User’s Mental Model

If a driver says “ 상호검색” , the navigation display “ 상호검색” interface. So the mapping can be easily learned and remembered.

- Driver can easily choose the menu by saying left, right, up, down. The user naturally thinks that the 4 triangles can be used in order to shift menu.

Selective Attention and Focus

Focused on the Voice User Interface, so the GUI might be complex due to commands.

Focused on the Voice User Interface, so the GUI might be complex due to commands.

Design for Error

This prototype can undo activity, when the driver make a command which the drive do not want.

This prototype maps the various voice commands to a certain function.

Focus Area II

2. Search map

Point out the designated location and move to four directions by menu selection or voice command

Function

●Move four directions●Zoom in/out map ●Indicate current location

Links> Choose search type

Object Map information

Sequence• Move the map according to four directions.• Zoom in the map• Zoom out the map• Move to current location

• The arrows represent the direction. • Zoom in, zoom out button and Move to current location button. • A user tells arrow’s direction.

• Advantage: A user can identify the menu intuitively. • Disadvantage: When a user zooms in or out, he should iterate voice command.

• This does not show menu bars at first. • When a user tells a menu name, the pull-down menu, will be appeared. • Advantage: Sub menus enable a user to select specific sub menus like magnifications.• Disadvantage: When a user speaks menu name, the sub menus will be represented.

Evaluation

Affordances • Four direction arrows and command buttons enables a user grasp the function of menus because four direction arrows and command buttons have visibility

• Menus are not appeared until a user commands an initial menu.

The seven stages of action

• Good visibility.

• Natural Mapping.

• Use both knowledge in the world and knowledge in the head.

• Easy to use.

• Good visibility, when sub-menus are displayed.

• Feedback. • Uses knowledge in the head.

• Difficult to use.

User’s mental model

• The arrows are natural mapping.

• When a user commands arrows’ direction, the map focus is moved according to the command.

• Zoom in/out buttons are bad case of natural mapping because a user can not expect how much the map will be magnified or reduced.

• Driver may not know what he can do in this prototype. Thus, this is bad case of natural mapping. • The sub-menus are good natural mapping.
