Input devices for mobile gaming consist of hard keypad (HK) and soft keypad (SK). Different interaction for both input devices have an impact on usability and player experience. Although there are publications that evaluate on input devices and game, little is known on how HK and SK affect...

Location-based mobile learning (LBML) is a type of mobile learning in which the learning content is related to the location of the learner. The evaluation of LBML concepts and technologies is typically performed using methods known from classical usability engineering, such as questionnaires or...

Projectors shrink in size, are embedded in some mobile devices, and with the miniaturization of projection technology truly mobile projected displays became possible. In this paper, the authors present a survey of the current state of the art on such displays. They give a holistic overview of...

This paper disseminates work from the European Give&Take project, which aims at co-designing service sharing among senior citizens based on a mobile and distributed platform. With this project as a frame, the authors' paper addresses methodological considerations of participation in co-design...

This paper presents the process and results of a set of studies within the ABBI EU project, with the general aim to co-design wearable technology (an audio bracelet) together with visually impaired children, starting at a young age. The authors discuss user preferences related to sounds and...

Notification displays have the potential to make smartphone notifications easier to manage when a user is committed to a primary task. The authors investigate the impact of negotiating notifications with six notification displays on a typing task. The results from their lab experiment with 30...

Wearable computing has a huge potential to shape the way we interact with mobile devices in the future. Interaction with mobile devices is still mainly limited to visual output and tactile finger-based input. Despite the visions of next-generation mobile interaction, the hand-held form factor...
