Chapter 2: Trends Towards Mobility 15 The notion of gaps in life implies that mobile content is particularly interesting while we are in between other activities. This necessarily shapes mobile content and the devices used to access it. For instance, it is not very enjoyable to view a full-length movie on a small hand-held screen (just try it!), but watching a two-minute trailer of the same movie feels fi ne while waiting for the bus. 2.1.2 Continuous and Nomadic Mobile Use Mobile use can be either continuous or nomadic (Rosenberg 1998). Continuous refers to using the mobile device while actively moving, whereas nomads can be stationary for long periods of time. For instance, when a typical corporate traveller establishes her mobile offi ce in a hotel where she is staying for a few days, she is not at her home base, but she is not altogether mobile all the time either – she is a nomad camping out temporarily. She can invest some effort in making her environment more convenient for the limited time she will spend there. She may wish to struggle through the ordeal of arranging offi ce network access from the hotel, which she would not bother to do if she was going to be there only for an hour or two. Some of the requirements for con- tinuous mobile use can thus be relaxed for nomadic users. Nomadic situations also highlight people’s desire for calm and serenity, even for a short while, to be able to immerse themselves in something other than the real world. For instance, after running madly through the whole day, it feels relaxing to take the MP3 player out of your pocket, sit down, put on the headset, start listening to your favou- rite band – and close your eyes.
