Verbal and visual representations in task redesign: how different viewpoints enter into information systems design discussions
2005
We explore an important phase of information systems design (ISD), namely task redesign, and especially how different viewpoints enter into the dis- cussions. We study how one particular visual representation, a process diagram, is interpreted and how alternative, even competing, representations are produced verbally. To tie the visual and verbal representations and the representational prac- tices to wider social practices, we develop and use the Extended Three-dimen- sional Model of discourse. Visual representations emerged as focal in bringing in the different viewpoints and as reference points for discussions. Our model pro- vided a focused and powerful means to unveil for the outside r…
SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT
2011
8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …
A Matrixulation Method for Mapping an E-learning Platform Designer’s Conception of Learning: A Pilot Study
2004
This paper presents a method for analyzing human conceptions related to e-learning, based on positioning data on what is called here a learning matrix. The set of dimensions comprising the matrix distinguish between emphasis on individuality and sociality in learning, between viewing learning as knowledge adoption and as knowledge construction, and between viewing learning as subjective and as objective to time. The learning matrix is used to visualize and compare conceptions of learning extracted from literature and from individual perceptions of learning, revealed through interviews. This study supports the development of e-learning environments and casts light on different conceptions of…
A fuzzy methodology to alleviate information overload in elearning
2013
Some aspects of eLearning experience can be en- hanced in a very natural way by using the basic tools offered by fuzzy logic. As a matter of exam- ple, consider the uncontrolled growth of informa- tion produced in a collaborative-oriented context, in which each participant (e.g. students, teachers) is able to insert and share new contents (e.g. com- ments, texts) concerning a university course. All the incrementally added pieces of information can be evaluated in several ways: by the intervention of a “dictator” (e.g. the teacher), using a rating form, or even according to the frequency of access. As contents rapidly become unusable for the effects of information overload, basic tools of fu…
Taking the Advantage of Smartphone Apps for Understanding Information Needs of Emergency Response Teams’ for Situational Awareness: Evidence from an …
2016
In search and rescue (SAR) operation, a lot of information is being shared among different emergency response groups. However, one of the key challenges experienced by these rescue groups during SAR operation is obtaining the complete awareness of the situation from the shared information. Moreover, one of the key actions of rescue leaders is to get the needed information in order to coordinate effectively with other teams and perform well. So, in this study we conduct an indoor fire drill with the help of Smartphone application with two settings (without SmartRescue smartphone application and with SmartRescue smartphone application) to find out what type of information is mostly communicat…
Planning in Collaborative Stigmergic Workspaces
2011
The paper investigates how the engineered capabilities of structuring the knowledge encoded in collaborative workspaces affect the collective intelligence of its users. The investigation is made for the particular case of collaborative planning and is grounded on the theoretical framework of stigmergic systems. The knowledge structure encoded in collaborative workspaces in the form of a conceptual hierarchical task network is analysed by building a multi-agent simulation to evaluate the performance of different planning strategies. The results show that different representational complexities of collaborative planning knowledge have a great impact over the collective intelligence when the u…
Capabilities and Affordances of Virtual Worlds for People with Lifelong Disability
2013
Using technology is of great value for people with lifelong disability (PWLD). The Internet can help PWLD to be more independent, to be socially active, and to participate in a range of activities. Virtual worlds (VWs) offer an environment with technology capabilities for interaction, rendering, and communication. The ability to take advantage of these capabilities may depend on the technology and the ability of the person utilizing it. Using a qualitative study we aimed to explore the differences of ability required to use these capabilities and make capabilities into affordances for PWLD. We found there were differences in PWLD’s ability to utilize the capabilities offered and conclude th…
A Novel User Interface for Knowledge Base Browsing
2019
Abstract Intuitive user interfaces have been of great concern for GUI developers. The current research, who deals with their designing, faces the term intuitive constantly. The main question is how can the Interface be intuitive? For the moment, the researchers try to provide a very intuitive generic user interface that can be used in a variety of applications. In this paper we provide a solution that can model any applied ontology into a honeycomb menu. The hexagonal shape of the honeycomb has attracted the attention of humans for centuries. As a relevant consequence, the final user can browse any knowledge base very easily with the aid of this interface. Another useful feature is that pro…
Designing the Didactic Strategy Modeling Language (DSML) From PoN: An Activity Oriented EML Proposal
2018
[EN] This paper presents the design of the didactic strategy modeling language (DSML) according to the principles of Physics of Notations (PoN). The DSML is a visual and activity-oriented language for learning design characterized by the representation of different activities according to the nature of the task. Once the language is designed, a blind interpretation study is conducted to validate the semantic transparency of the learning activity iconography. The results of the paper allow to refine the icons. In addition to this, an authoring tool for DSML, which is integrated to an LMS, is presented. As a result, a model driven course was designed as a DSML pre-validation.
Manual Guiding in Peer Group Interaction: A Resource for Organizing a Practical Classroom Task
2013
How might someone carry out an educational task by moving an object or by guiding another person in doing so? This article describes the practical work of a group of school students as they work through an object-based physics task. It analyzes a recurrent practice whereby one student influences another's embodied conduct, either by manually guiding an object (a weight, a moveable plank, and so on) or by guiding the hand of another student as they manipulate an object. We show how the practices of manual guiding involve a range of embodied and contextual resources. They serve to maintain and restore the progressivity of the task in two environments: corrective sequences and local projects i…
