The paper outlines an approach to CSCW systems design based on the concept of ‘coordination mechanisms.’ The concept of coordination mechanisms has been developed as a generalization of phenomena described in empirical investigations of the use of artifacts for the purpose of coordinating cooperative activities in different work domains. On the basis of the evidence of this corpus of empirical studies, the paper outlines a theory of the use of artifacts for coordination purposes in cooperative work settings, derives a set of general requirements for computational coordination mechanisms, and sketches the architecture of Ariadne, a CSCW infrastructure for constructing and running such malleable and linkable computational coordination mechanisms.

Tackling the Digitalisation Challenge: How to Benefit from Digitalisation in Practice

Near Field Communication (NFC) as a promising short range wireless communication technology facilitates mobile phone usage of billions of people throughout the world that offers diverse services ranging from payment and loyalty applications to access keys for offices and houses. Eventually NFC technology integrates all such services into one single mobile phone. NFC technology has emerged lately, and consequently not much academic source is available yet. On the contrary, due to its promising business case options, there will be an increasing amount of work to be studied in the very close future. This paper presents the concept of NFC technology in a holistic approach with different perspectives, including communication essentials with standards, ecosystem and business issues, applications, and security issues. Open research areas and further recommended studies in terms of academic and business point of view are also explored and discussed at the end of each major subject's subsection. This comprehensive survey will be a valuable guide for researchers and academicians as well as for business world interested in NFC technology.

A Survey on Near Field Communication (NFC) Technology

This paper summarizes the results of our concept development for NFC-enabled wireless charging -- i.e., an add-on to the existing NFC operating modes that implements charging power transmission and charging power reception with associated control functionality. When compared to dedicated wireless charging solutions, integration of NFC and wireless charging into the same implementation will entail more compact and cost-efficient charging interfaces for portable devices, a more pervasive charger infrastructure in future with reduced costs, and the possibility of integrating NFC-based services into charging applications. We propose to the NFC community a closer investigation of use cases, the business potential, and technical implementation of NFC-enabled charging. This should lead to a road map for its wider adoption, pave the way to its standardization, technology development, and commercial application, and also support enhancement of power transfer capability in other NFC applications alongside wireless charging.

NFC-Enabled Wireless Charging

A mobile device (102, 202, 302) for enhancing context awareness in social networking comprises a processor (220) for processing data, a memory (222) for storing data, a wireless transceiver (224, 224B) for wirelessly transmitting and receiving data relative to remote devices, a short-range wireless transceiver (224, 224A), e.g. an NFC transceiver, for wirelessly transmitting and receiving data relative to remote devices equipped with a compatible short-range interface, a social contact registration logic (206, 604) configured to obtain information from a mobile communications device of a social contact via the short-range wireless transceiver, the information identifying the social contact and/or the mobile communications device of the social contact, a context detection logic (206, 608) configured to obtain, via the short-range wireless transceiver, data distinctive to and provided by a tag disposed in a location accessible via the short-range data transfer, said distinctive data being thus indicative of the current location-based context of the mobile communications device and the user thereof, and a context notification logic (206, 606) configured to transmit an indication of the detected location-based context to a remote entity, such as a server, via the wireless transceiver in order to enable providing at least one social contact of the user of the mobile communications device with knowledge of the current context.

Software testing is often a complex process potentially involving a large number of geographically distributed people with different perspectives and competencies. Software testers, software developers and project managers engage in discussions about the software errors found, they negotiate the relative importance of the bugs, they allocate responsibilities and resources, they coordinate who is doing what, etc. They talk about bugs. In order to coordinate and manage talking about bugs, a number of means for coordination are applied. The aim of this paper is to analyze coordination work in software testing in order to promote general requirements for computer support. We have studied the testing of more than 200,000 lines of code at Foss Electric, a Danish manufacturing company, and focused on two aspects: Firstly, the coordination activities related to the process of distributed registration, classification, diagnosis, correction, and verification of software errors, as well as the monitoring of the state-of-affairs of testing activities. Secondly, the mechanisms used to support the coordination. The analysis resulted in the identification of the need for computer support for coordinating this part of the software testing process, e.g., support of distributed classification, routing of information, and facilities providing an overview of state of affairs.

Wikipedia is widely known encyclopedia in the web updated by volunteers around the world. Mobile and location based wiki with NFC, however, brings forward the idea of using Near Field Communication tags as an enabler for seeking information content from wiki. In this paper we shortly address how NFC infrastructure can be created in a city for the use of location-based wiki. The users of the system can lead local information from the Wikipedia system and also update the location-based content. We present an implementation of such a system. Finally, we evaluate the restrictions of the technological system, and delineate further work.

Location-Based Mobile Wiki Using NFC Tag Infrastructure

Physical browsing is a new intuitive human computer interfacing paradigm for mobile users. Services, such as information retrieval, peer to peer communication, payment or ticketing, and professional applications can be initiated by simply touching an object with a users personal device. This paradigm can be implemented with RFID technology. A number of major companies in the fields of mobile communications, electronics and financing have joined forces in an effort to commercialise this human computer interaction paradigm with the brand name Near Field Communication (NFC). NFC is based on existing technology using 13.56 MHz RFIDs and international standards. NFC forum is creating standards and recommendations for the upper level protocols and application models. VTT is leading a European-wide project which develops and pilots NFC technology. This report describes the findings and results of the first project year. The report outlines the concept of Physical browsing, NFC technology, its main applications, and describes a pilot case with a meal service for elderly citizens. An NFC Bluetooth gateway prototype has been designed and the first experiments are briefly described. Security and privacy issues relevant to NFC are described. The main business models, namely those driven by financial institutions, mobile operators or other parties, are discussed. A look at major trials and roll-outs of contactless payment is given. Some solutions to the dilemma of scarce NFC services and low penetration of NFC phones are suggested.
