Adding some smartness to devices and everyday things

Abstract: In mobile computing, context-awareness indicates the ability of a system to obtain and use information on aspects of the system environment. To implement context-awareness, mobile system components have to be augmented with the ability to capture aspects of their environment. Recent work has mostly considered location-awareness, and hence augmentation of mobile artifacts with locality. We discuss augmentation of mobile artifacts with diverse sets of sensors and perception techniques for awareness of context beyond location. We report experience from two projects, one on augmentation of mobile phones with awareness technologies, and the other on embedding of awareness technology in everyday non-digital artifacts.

Sensor-Based Context-Awareness for Situated Computing

Abstract: It can be argued that pervasive access to information and services becomes more valuable when they are related and adapted to the real world situations of their use. We discuss sensor-based approaches to awareness of such situations based on experience from two projects, one investigating context-awareness as add-on technology for mobile devices, and the other exploring the use of everyday things as context suppliers.

Developing User Interfaces for Wearable Computers: Don't Stop to Point and Click

Abstract: Typical usage scenarios for wearable computers are support of users doing a certain task, eg aircraft repair or military applications If the user is moving while using the wearable some restriction for the user interface apply In this paper we present some of these restrictions and suggest a wearable user interface taking these findings into account 1 Introduction The term "Wearable Computer" is used for a wide range of personal technologies, such as watches and mobile phones with enhanced
