User testing At air base N.º 5

2 sessions6 air force trainers

We recorded notes + interviews

Tests & Results - highlights• Trainers: average age 42, regular computer users• No prior virtual world experience• Found it an useful asset in support of practice• Required connection with prior safety inspection

checklist• It is necessary to increase the level of detail• Interaction is adequate and sufficient• More procedures are required to cover the full set

of basic operations

Future steps• Mixed teams of human and computer avatars• Automated registration of objects by graphic

designers and behaviour definition by trainer (not software engineers)

• Implement system in alternative 3D platform for improving separation of concerns
