Goal understanding and communication of requirements are vital for ensuring that large and complex project organizations collaborate efficiently. We have used a design science approach to explore and address the problem of communication for large IT projects. We designed a method for avoiding communication gaps by eliciting information regarding stakeholders and information flows. The MAPS (Mapping...
Different from current researches on Flickr group recommendation approaches that recommend groups to either users or images, this work proposes a unified framework that recommends groups to both users and images. Four types of entities in the Flickr system (users, tags, images, and groups) are integrated into a tetradic model, and then we uses tetradic decomposition to discover the latent semantic...
Adaptive Collaboration (AC) has been proven and verified to be a promising methodology to conduct collaboration. AC follows an iterative and dynamic process that includes phases of role negotiation, agent evaluation, role assignment, role playing, and role transfer. However, AC is complex, and the benefits of AC are not easily observed. In particular, the benefits must be obtained through complicated...
The advantage of using collaborative brain-computer interfaces in improving human response in visual target recognition tests was investigated. We used a public EEG dataset created from recordings made using a 32-channel EEG system by Delorme et al. (2004) to compare the classification accuracy using one, two, and three EEG signal sets from different subjects. Fourteen participants performed a go/no-go...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
In this talk we discuss our experience making state of the art software technologies including vector functional programming, collaborative analytics and visualization consumable by demanding customers we call Thinkers. The emerging discipline of Computational Science brings Thinkers and Software Experts together to create environments for Thinkers. Thinkers are well educated domain and problem focused...
In this paper we are focusing on the collaborative competencies associated with group learning and required by many of today's complex, fast-changing learning environments. Our pedagogical approach called Learning to learn together (L2L2) was implemented in the Metafora project's web-based environment and provides various tools to support collaboration, mutual engagement, and conflict management....
This position paper explores the idea that the blackboard system metaphor can be used to enrich collaborative ACM systems where there is need to mobilize knowledge workers with different areas of expertise for solving a case. Inspired by this metaphor, we outline how blackboards can be perceived both as a snapshot visualization of case folder with goal achievement status across lines of work, and...
In today's social context, the role of designers has been shifting gradually with design evolution. Along with the proposition of design thinking, service design and transformation design, designers work more with people than merely for people. And that makes designers play the role of facilitators more in the design processes to promote co-design with various stakeholders for solutions and strategies...
The situation when the orientation is lost is mentally demanding for blind people and is mainly solved with help of passer-by people. We conducted a series of user studies (37 participants) which analyzed the feelings and behavior patterns of blind people when recovering from loss of orientation. Blind people find the help of passer-by people as unpleasant and of poor quality thus the studies focused...
Learning scenarios are formally represented through Educational Modeling Languages (EMLs). The IMS-LD is a commonly used EML and several compliant visual editors are being created for the authoring of learning scenarios. However, these editors have a limited level of expressiveness. The LPCEL Editor facilitates the authoring process with a visual tool that includes the mechanisms for a collaborative...
The increased complexity in Product Service Systems development goes hand in hand with complex heterogeneous networks. A Human-Centred Design approach has been taken to understand such networked collaboration and to develop a framework having user-experiences guiding communication and collaboration among parties. The current work elaborates on the development of a framework for networked collaboration...
Preemptive conflict detection is the act of detecting a potential merge conflict at an earlier stage than at check in time, and informing the involved developers about it. Researchers have proposed a number of tools and techniques to detect potential merge conflicts. However, barely any study has been conducted to investigate whether the adoption of such tools and techniques brings benefits to developers...
Technology Navigator is an online tool, developed by IEEE volunteers, which enables students, faculty and professionals in engineering and the sciences to discover engineering content and events relevant to them, including conferences, publications, standards, and published articles. Tags and related tags, often based on a shared “market language,” are filtered across multiple disciplines and industry...
Although the application of sketch-based chart annotation is not pervasive in management, the use of sketchmarks can provide numerous benefits to managerial discussions. The collaborative use of chart annotations can support management teams in their decision making based on quantitative charts by visually eliciting and capturing interpretation processes, clarifying basic assumptions, stimulating...
This paper presents an empirical study of two student pairs collaborating on two small products design session in both face-to-face and distributed settings while using computer-mediated communication (CMC) technologies and a collaborative virtual environment (CVE). To gain insight about the way designers communicate and collaborate, the observation focused on how much time the students worked together...
We present a layout algorithm for grouping the user's tags within a folksonomy, aimed at easing the visualization and exploration of a large set of tags and their complex relationships. We introduce the possibility of (i) labeling linking tags to construct a network of tags and (ii) defining the concrete meaning of a tag by choosing the right definition extracted from Wikimedia projects or by writing...
Scripts are the computational solution proposed in the computer-supported collaborative learning (CSCL) field to guide and support potentially fruitful interactions in terms of learning benefits. However, when applying these scripts to real contexts, unexpected situations occur that forces to change the script on the fly. In a blended learning situation, in which online activities and face-to-face...
A curriculum knowledgebase, based on a visual model and ontology, is presented part way through its development lifecycle. The early modelling stages have yielded a means to tackle the complex curriculum structure, an operational knowledgebase and consensus among the domain experts on the ways in which the academic curriculum development team, students and administrators will interact with the curriculum...
