This paper discusses the use of gesture and non-speech audio as ways to improve the user interface of a mobile music player. Their key advantages mean that users could use a player without having to look at its controls when on the move. Two very different evaluations of the player took place: one based on a standard usability experiment (comparing the new(More)
The development of interactive technology is often based on the assumption of need to reduce the physical action and cognitive load of the user. However, recent conceptualizations, supported by research in various fields of science, emphasize human physical action in cognitive processes and knowledge formation. In fact, physical and closely related(More)
At present most sound design methods for non-speech sounds in auditory interfaces are based on empirical knowledge, often resulting in sounds derived from random selection or the personal preferences of the designer. A more theoretical design background is required which will create a framework that can be integrated with a practical approach to create the(More)
In the traditional use-oriented approach, only a fraction of gestures are taken as relevant to interaction. In this paper we argue that gestures should not be handled only as isolated objects of application use, but they should rather be understood as dynamic moments of embodied presence belonging to an experiential chain of different movements which has(More)
This study examines three design bases for speed regulation messages by testing their ability to function across modalities. Two of the design bases utilise a method originally intended for sound design and the third uses a method meant for tactile feedback. According to the experimental results, all designs communicate the intended meanings similarly in(More)
The large scale deployment of mobile applications inevitably affects our daily lives and the whole culture. Not all of these effects are desirable. In a market economy, ethical issues are not the foremost drivers in the development of technology. In this paper, we ask whether the mobile human-computer interaction community could take an active role in(More)
