Contextualise! personalise! persuade!: a mobile HCI framework for behaviour change support systems

Sebastian Prost, Johann Schrammel, Kathrin Röderer, Manfred Tscheligi

This paper presents a context-aware, personalised, persuasive (CPP) system design framework applicable to the sustainable transport field and other behaviour change support system domains. It operates on a situational, a user, and a target behaviour layer. Emphasis is placed on interlinking each layer's behaviour change factors for greater effectiveness. A prototype CPP system for more sustainable travel behaviour is introduced to demonstrate how the framework can be applied in practice.

Spotted: most app launches happen from other apps

Quite related to some of our own work.

Oh app, where art thou?: on app launching habits of smartphone users

Alina Hang, Alexander De Luca, Jonas Hartmann, Heinrich Hussmann

In this paper, we present the results of a four-week real world study on app launches on smartphones. The results show that smartphone users are confident in the way they navigate on their devices, but that there are many opportunities for refinements. Users in our study tended to sort apps based on frequency of use, putting the most frequently used apps in places that they considered fastest to reach. Interestingly, users start most apps from within other apps, followed by the use of the homescreen.

An alternative to pinch-to-zoom

Good work, and about time. If the current ui is the "wimp" of mobiles, hopefully we won't have to wait as long as we did with wimp to find what's next.

Toward compound navigation tasks on mobiles via spatial manipulation
Michel Pahud, Ken Hinckley, Shamsi Iqbal, Abigail Sellen, Bill Buxton

We contrast the Chameleon Lens, which uses 3D movement of a mobile device held in the nonpreferred hand to support panning and zooming, with the Pinch-Flick-Drag metaphor of directly manipulating the view using multi-touch gestures. Lens-like approaches have significant potential because they can support navigation-selection, navigation-annotation, and other such compound tasks by off-loading navigation to the nonpreferred hand while the preferred hand annotates, marks a location, or draws a path on the screen. Our experimental results show that the Chameleon Lens is significantly slower than Pinch-Flick-Drag for the navigation subtask in isolation.
