Users as sensors: creating shared experiences in co-creational spaces by collective heart rate

The last decade has witnessed a growing interest in design information technologies and interfaces that support rich and complex user experiences, including satisfaction, joy, aesthetics, and reflection. It is high on the agenda to extend and intensify the overall (user) experiences with the help of appropriate technology. This paper presents a pilot study on using collective heart rate visualized in the indoor ice rink to bring intensiveness into the audience experience. The aim of the study was to explore the usefulness and affect of the developed collective heart rate and to evaluate it as one of the new features that could enhance the user experience among the audiences in wide public events. In particular, the study focuses on studying the significance of the technological equipment in creating a sense of collectiveness and togetherness of the audience. This research is important because it introduces a new idea of audience involvement with the techniques of mobile phones and heart rate measurement belts. The results, positive and negative, of the study widen the field of physiological sensing technologies and facilitate the diffusion of these techniques into different public events with the large number of audience.

Mobile video sharing: documentation tools for working communities

Although video sharing in web is used in learning, most video sharing services are not originally designed to be used as a learning application. In addition, most of these systems were designed to use via computer and with a web browser. Our solution, MoViE (Mobile Video Experience), is designed to be used in learning applications especially with mobile devices. MoViE is a social media service that enables users to create video stories using their mobile phones. Services web interface is light and it works with all modern mobile phone browsers. In order to support automatic tagging of videos we designed a specific client for Symbian S60 platform that uses gps and cell tower data for creating tags for location, place and weather. In addition, MoViEs mobile client application makes uploading process even faster and makes possible to utilize smart tagging suggestions. The S60 MoViE client was used by the staff of Pori Jazz festival organization during the festival in summer 2009 for documenting the festival arrangements. They tried to capture unsuccessful, broken and bad things around the festival area. The aim was to use the videos for learning how to do things better next year.

Social navigation with the collective mobile mood monitoring system

At large-scale events, people could benefit from the experiences of others to help find interesting areas. Also, more and more pervasive and ubiquitous mobile devices could be utilized for navigation in different situations. In this paper, we will present a manual input mobile computing platform for monitoring and collecting information about peoples moods at a large-scale public event. In addition to places and venues, moods are represented in real time on a public map as a social navigation recommendation system. Furthermore, as a step towards future work, we utilized consumer-level brainwave measurement equipment to build a mobile prototype research application for semi-automatic mood monitoring. The aims of the field pilot study and the follow-up examination were to explore the usefulness and effect of the mobile mood sharing system that was developed on event visitors. In particular, the study focuses on benefits of the social aspects, in addition to spatial and semantic navigation. With todays available technology, we have to balance in the comfort zone between required user attention and user experience. In any case, the results of the study broaden the field of social mobile applications and facilitate the diffusion of these into different large-scale public events.

Enriching shared experience by collective heart rate

The last decade has witnessed a growing interest in design information technologies and interfaces that support rich and complex user experiences, including satisfaction, joy, aesthetics, and reflection. It is high on the agenda to extend and intensify the overall (user) experiences with the help of appropriate technology. This paper presents two pilot studies in which mobile devices were used to enrich shared experiences by measuring user generated collective heart rate. It is visualised in the indoor ice rink and utilised in exertion games to bring intensiveness into the audience experience. The aim of the study was to explore the usefulness and affect of the developed collective heart rate system and to evaluate it as one of the new features that could enhance the shared experience among the audiences in co-creational spaces. In particular, the study focuses on studying the significance of the technological equipment in creating a sense of collectiveness and togetherness of the participants. This research is important because it introduces a new idea of user involvement with the techniques of mobile phones and heart rate measurement belts. The results, positive and negative, of the study widen the field of physiological sensing technologies and facilitate the diffusion of these techniques into different public events.

Design of a Manageable WLAN Access Point

This paper presents the design and prototype implementation of a manageable WLAN Access Point (mAP). mAP has been developed for managing WLAN Quality of Service (QoS), frequency selection, client configuration, and for collecting a wide range of management information. The prototype is implemented using a Linux platform. With the presented architecture, the mAP functionality can be easily extended by adding new management functions and automated services.
