1. Usability Testing of mobile applications: a comparison between lab and field (Kaikkonen)

   • same tasks just change of context of use

2. Usability testing of mobile device: a comparison of 3 approaches (Holtz Betiol)

   • lab with PC & phone emulator
   • field with mobile phone
   • lab with mobile phone
   • no mobility in any scenario so limited findings
