以体验为先导——体验经济时代设计的新思维

本文从体验、体验需求及体验设计等三个方面对体验经济时代以体验为先导的设计新思维作了初步的探讨。体验是人们对所经历的事、物及环境在生理、心理上的综合感受和情感升华,可分为表层的感官体验和深层的情感体验。不同于外部的物质需求,体验需求是人的内在心理需求,在体验经济时代,设计将超越功能和形式,以创造积极美好的消费体验为核心。情感性、策略性、开放性、个性化及以用户为中心等特点集中表明了体验经济时代设计的人本主义特征。

Distributed High-End Audio-Visual Content Creation: An Experience Report

In the recent years the world has witnessed an unprecedented expansion in the global audio-visual industry and actions have been initiated to strengthen its actors, especially in filmmaking and video production. Companies seeking ways to improve their performance and productivity and become more competitive are investing in modern digital technologies. High-performance computingsystems are found today even in small production facilities. Yet, little effort has been used to implement activities other than production/post-production and even less tointegrate the whole cycle of contentdevelopment and creation within a networkedcollaborative environment. This paper reportsthe experience of the DAViD project aiming toestablish ways to interact and collaborate during pre-production phases. Several benefitshave been demonstrated, such as reduction ofthe overall production time and cost, increasedproductivity and increased ability to executecomplex, multi-company productions in shortertimes and lower budgets.

On Using B in the Design of Secure Micro-controllers: An Experience Report

The stepwise formal development of safety critical software is now a well established engineering practice, noticeably in railway systems. However, it has not been applied as successfully to hardware development, where formal methods are mainly used for verification and gate level transformations and optimizations. In this paper, we report our recent experience in the stepwise formal development of a real macro-cell, that opens the way to the design of synchronous digital circuits with zero functional bugs. We propose a development flow suited for obtaining proven correct-by-construction circuits that further possess additional robustness properties desirable for secure chips. The reported work is prospective and is meant to show the feasibility of such a technique for high confidence trustful devices.     

Peer observation of teaching in the online environment: an action research approach

Abstract This paper describes a collaborative action research approach used to explore peer observation of teaching (POT) within the online environment. Although POT has become familiar in face‐to‐face teaching contexts, little is understood of its potential role in online settings. We conducted ‘virtual’ focus groups to explore the experience and views of 28 teachers and subjected our data to a thematic analysis. This informed the implementation of an innovative programme of POT, ‘Peer‐to‐peer Reflection on Pedagogical Practice’ (PROPP) among tutors of a Web‐based MSc in International Primary Health Care at University College London. Modeled on an action learning set, the programme encourages collaborative reflection on teaching practices, based on participants' specific examples of online teaching. The PROPP model is consistent with Quality Enhancement, which we distinguish from Quality Assurance. Here, we describe the implementation of the PROPP programme within an action research framework and identify the factors that we consider critical to the success of peer observation within online courses. We highlight examples of aspects of teaching that have been discussed within the PROPP programme and offer suggestions of the kinds of evidence that could be incorporated into a portfolio to demonstrate the effectiveness of such an initiative.     

Modeling complex marine ecosystems: an investigation of two teaching approaches with fifth graders

Abstract  This study investigated acquisition and transfer of the modeling ability of fifth graders in various domains. Teaching interventions concentrated on the topic of marine ecosystems either through a modeling-based approach or a worksheet-based approach. A quasi-experimental (pre–post comparison study) design was used. The control group ( n  = 17) received a traditional worksheet-based instruction about ecosystems, whereas the experimental group ( n  = 16) received an instruction which was based on Stagecast Creator, an object-oriented programming tool, and a set of modeling-based curriculum materials. Paper-and-pencil tests were used both before and after the study to evaluate students' development of specific modeling skills. The data analysis followed both qualitative and quantitative methods. The findings of the present study indicate that (i) the development of modeling ability was effectively enhanced through the modeling-based approach, since, after instruction, students were able to transfer those aspects to unfamiliar contexts; in contrast, the more traditional worksheet-based approach did not promote the development of the same aspects of the modeling skill; and (ii) Stagecast Creator enabled students to construct, test, revise and validate dynamic computer-based models of a marine ecosystem through building, testing and debugging complex rules, routines and programs for simulating multiple behaviours and processes of marine species.     

Increasing Constraint Propagation by Redundant Modeling: an Experience Report

This paper describes our experience with a simple modeling and programming approach for increasing the amount of constraint propagation in the constraint solving process. The idea, although similar to redundant constraints, is based on the concept of redundant modeling. We introduce the notions of CSP model and model redundancy, and show how mutually redundant models can be combined and connected using channeling constraints. The combined model contains the mutually redundant models as sub-models. Channeling constraints allow the sub-models to cooperate during constraint solving by propagating constraints freely amongst the sub-models. This extra level of pruning and propagation activities becomes the source of execution speedup. real-life nurse rostering system. We perform two case studies to evaluate the effectiveness and efficiency of our method. The first case study is based on the simple and well-known n-queens problem, while the second case study applies our method in the design and construction of a real-life nurse rostering system. Experimental results provide empirical evidence in line with our prediction.     

Tool Integration in Distributed Environments: an Experience Report in a Manufacturing Framework

Due to enormous pressure from national and international marketplaces, computer integrated manufacturing ( cim) has become a tremendously important area for both research and development. However, the current state of the art is still characterized by islands of automation. In order to connect these islands, appropriate frameworks have to be developed to integrate heterogeneous computer aided design ( cad) tools. We present in this paper a federated approach to tool integration in distributed and heterogeneous environments making tools evolve in an autonomous way. We have experimented this approach by integrating propel and spex cad tools in the dmms ( design management and manufacturing system) environment backed by a common pcte providing an open repository for software development. We use in our experiment an implementation of pcte 1.5 named Emeraude V12.5, product of gie emeraude repository.     

The UJI Online Robot: An Education and Training Experience

This paper describes a complete vision-based online robot system that allows controlling both an educational and an industrial robot via web. We address some of the limitations of current similar systems particularly concerning the user interface. Some of its novel features are: its adjustable autonomy, so that the user can decide the right level of interaction from high-level voice commands down to mouse clicks, reducing in this way the cognitive fatigue resulting from remote operation; the interface is predictive, by using a 3D virtual environment endowed with augmented reality capabilities, the user can predict the results of the actions before sending the command to the real robot. Thus, network bandwidth is saved and off-line task specification is possible. This high level interaction is possible thanks to some built-in modules for performing basic tasks such as automatic object recognition, image processing, autonomous grasp determination and speech recognition. Finally, the system has been tested by means of an application in the Education and Training domain. One hundred undergraduate students have been using the web-based interface in order to program Pick and Place operations with the system. The results show performance, statistics, connection rates, and the students' opinions, as a way of evaluating the convenience and usability of the user interface.
