- This paper describes our studies of mediaspaces which are embedded within public places in organizations so as to examine the hypothesis that individuals might benefit even when working apart - from opportunities for light informal interaction. A set of full-scale prototypes were used and assessed over extensive periods of time. The informal observations and reflection in design of these places have been supplemented by formal studies. We found that great care needs to be taken when designing these places from an architectural point of view. For some of the places, we would like to suggest using architectural features when altering the room rather than technology. In other settings, the artful deployment of communication media might be more effective.

DJ scratching performance techniques : Analysis and synthesis
- 2003
-
Ingår i: Proc. Stockholm Music Acoustics Conference. ; , s. 693-696
-
Konferensbidrag (refereegranskat)abstract
- Scratching is a popular way of making music, turning the DJ into a musician. Normally scratching is done using a vinyl record, a turntable and a mixer. Vinyl manipulation is built up by a number of specialized techniques that have been analysed in a previous study. The present study has two main objectives. First is to better understand and model turntable scratching as performed by DJs. Second is to design a gesture controller for physical sound models, i.e. models of friction sounds. We attached sensors to a DJ equipment set-up. Then a DJ was asked to perform typical scratch gestures both isolated and in a musical context, i.e. as in a real performance. He also was asked to play with different emotions: sad, angry, happy and fearful. A model of the techniques used by the DJ was built based on the analysis of the collected data. The implementation of the model has been done in pd. The Radio Baton, with specially adapted gesture controllers, has been used for controlling the model. The system has been played by professional DJs in concerts.

Eventcasting with a wearable computer

- Traditionally, interaction methods for wearable computers have focused on input to the computer itself, yet little has been done when it comes to allowing interaction with the surrounding environment. Pervasive computing, on the other hand, offers access to computational power from any place all the time, yet most interaction techniques utilize either physical hardware or monitoring of the user in order to receive input. This paper presents a novel form of interaction by which a wearable computer user can interact with and control a pervasive computing environment in a natural and intuitive manner. Using sensors, the user can be allowed to literally "throw" events into the environment as a way of interacting with devices and computers

Experiences of using wearable computers for ambient telepresence and remote interaction
- 2004
-
Ingår i: Proceedings of the ACM SIGMM 2004 workshop on effective telepresence ETP 2004. - New York, NY, USA : IEEE Communications Society. - 1581139330 ; , s. 2-11, s. 2-11

Konferensbidrag (refereegranskat)abstract
- We present our experiences of using wearable computers for providing an ambient form of telepresence to members of an e-meeting. Using a continuously running e-meeting session as a testbed for formal and informal studies and observations, this form of telepresence can be investigated from the perspective of remote and local participants alike. Based on actual experiences in real-life scenarios, we point out the key issues that prohibit the remote interaction from being entirely seamless, and follow up with suggestions on how those problems can be resolved or alleviated. Furthermore, we evaluate our system with respect to overall usability and the different means for an end-user to experience the remote world

Methods for interrupting a wearable computer user
- 2004

Ingår i: Proceedings. - Los Alamitos, Calif : IEEE Communications Society. - 076952186X ; , s. 150-157

Konferensbidrag (refereegranskat)abstract
- A wearable computer equipped with a head-mounted display allows its user to receive notifications and advice that is readily visible in her field of view. While needless interruption of the user should be avoided, there are times when the information is of such importance that it must demand the user’s attention. As the user is mobile and likely interacts with the real world when these situations occur, it is important to know in what way the user can be notified without increasing her cognitive workload more than necessary. To investigate ways of presenting information without increasing the cognitive workload of the recipient, an experiment was performed testing different approaches. The experiment described in this paper is based on an existing study of interruption of people in human-computer interaction, but our focus is instead on finding out how this applies to wearable computer users engaged in real world tasks.

- This paper describes the development of a fetch-and-carry robot to assist physically impaired people in an office environment. Different methods involving users are employed in the project, including the task analysis, Hi-Fi simulation trials and focus group sessions. Through an iterative design process, a prototype robot system has been developed, with an enhanced robot platform including a graphical user interface and natural language interface. The users' need for continuous feedback from the robot has led to the development of an animated character (CERO), which relates the two interface components and indicates the robot's current state by using simple gestures

Positioning with Bluetooth
- 2003

Konferensbidrag (refereegranskat)abstract
- This paper presents an evaluation of Bluetooth positioning in a general positioning platform. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with empirical tests. Three different ways of positioning with Bluetooth have been developed. With a registered positioning service a Bluetooth device has an active role in the positioning task as it sends a position on request. A Bluetooth device can also take a more passive role in a positioning task, where the unique address of the device is used by a connected device to look up respective position in a database. It is also possible to forward a position gained from the positioning platform using the peer to peer characteristics in Bluetooth. This paper does also contain a discussion on the theoretical time requirements for a positioning system based on Bluetooth. Empirical tests show that these requirements hold.

To help or not to help a service robot
- 2003

Konferensbidrag (refereegranskat)abstract
- This paper reports an experimental study in which people who had never encountered our service robot before were requested to assist it with a task. We call these visiting users "bystanders" to differentiate them from people who belong to the social setting and group in which the robot is operated in and thus are familiar with the robot. In our study 32 subjects were exposed to our robot and requested by it to provide a cup of coffee as part of a delivery mission. We anticipated that people in general would help the robot, dependent upon whether they were busy or had received a demonstration of the robot as introduction. Our results indicate that the willingness of bystanders to help a robot not only is a consequence of the robot initiated interaction, but equally depends on the situation and state of occupation people are in when requested to interact with and assist the robot.

Sharing experience and knowledge with wearable computers
- 2004
-
Konferensbidrag (refereegranskat)abstract
- Wearable computer have mostly been looked on when used in isolation. But the wearable computer with Internet connection is a good tool for communication and for sharing knowledge and experience with other people. The unobtrusiveness of this type of equipment makes it easy to communicate at most type of locations and contexts. The wearable computer makes it easy to be a mediator of other people knowledge and becoming a knowledgeable user. This paper describes the experience gained from testing the wearable computer as a communication tool and being the knowledgeable user on different fairs.

- The purpose of COVAX is to analyze and create the technical solutions required to provide access through the Internet to homogeneously-encoded document descriptions of archive, library, and museum collections based in the application of XML. This paper describes the development of the project, and the main achievements in building an information system of distributed XML databases containing document descriptions from libraries, archives, and museums emphasizing the conversion processes needed to transform legacy data to an XML environment.
