Project facts
The main objective of the UNIMOD-project was to contribute to the knowledge of multimodal, personalised user interfaces, and thus to improve the accessibility and use of electronic services.
Focus on users with cognitive challenges.
UNIMOD was partially financed by the VERDIKT-programme in
the Research Council of Norway. The total project cost was
estimated to 12.300.000 NOK.
UNIMOD run from 2007 to 2009.
User studies and development of prototypes were central
project activities.

Delivery situation
Work is performed in teams of two (driver / co-driver).
Delivery point may be outside or inside of buildings.
A delivery list is handed out at the start of the day.
Challenges: Customer may have moved mats to another spot
Multiple mat delivery with no specified mat position
Delivery based on personal note-taking and memorizing
No good way to share notes
Hard to describe complex environments textually (at least using few words)
Ordering of list based on other factors than geography

The delivery list
Multipage printout containing all information needed for delivery:
Address of delivery
Actual delivery point
General remarks on position (i.e. ”second floor, below exit-sign”, or ”talk to Frank”)
Product type
Quantity

The mobile prototype
Developed for ”off-the-shelf” devices.
Nokia N95 used as a development device.
Iterative development process.
Minimal information model.
Paper-prototyped, user-tested.

User feedback
More intuitive interface navigation.
Increase visual clarity in map symbols.
Support for multi modal comments to the delivery spot.

People with cognitive declines are many, and they are different.
User interfaces are not suitable for this user group.
More research is certainly needed.
