Multimodal data as a means to understand the learning experience
2019
Most work in the design of learning technology uses click-streams as their primary data source for modelling & predicting learning behaviour. In this paper we set out to quantify what, if any, advantages do physiological sensing techniques provide for the design of learning technologies. We conducted a lab study with 251 game sessions and 17 users focusing on skill development (i.e., user's ability to master complex tasks). We collected click-stream data, as well as eye-tracking, electroencephalography (EEG), video, and wristband data during the experiment. Our analysis shows that traditional click-stream models achieve 39% error rate in predicting learning performance (and 18% when we perf…
Learning to collaborate: Designing collaboration in a 3-D game environment
2006
To respond to learning needs, Computer-Supported Collaborative Learning (CSCL) must provide instructional support. The particular focus of this paper is on designing collaboration in a 3-D virtual game environment intended to make learning more effective by promoting student opportunities for interaction. The empirical experiment eScape, which encourages learners to solve problems collaboratively, is also presented. eScape is a design experiment, comprising both the process of designing a collaborative game environment and an empirical study where data is collected using a variety of methods and analysed, after which the findings and conclusions serve as a basis for further design work. By …
Deep multimodal fusion for semantic image segmentation: A survey
2021
International audience; Recent advances in deep learning have shown excellent performance in various scene understanding tasks. However, in some complex environments or under challenging conditions, it is necessary to employ multiple modalities that provide complementary information on the same scene. A variety of studies have demonstrated that deep multimodal fusion for semantic image segmentation achieves significant performance improvement. These fusion approaches take the benefits of multiple information sources and generate an optimal joint prediction automatically. This paper describes the essential background concepts of deep multimodal fusion and the relevant applications in compute…
Measurement, Prediction, and Control of Individual Heart Rate Responses to Exercise-Basics and Options for Wearable Devices.
2018
The use of wearable devices or "wearables" in the physical activity domain has been increasing in the last years. These devices are used as training tools providing the user with detailed information about individual physiological responses and feedback to the physical training process. Advantages in sensor technology, miniaturization, energy consumption and processing power increased the usability of these wearables. Furthermore, available sensor technologies must be reliable, valid, and usable. Considering the variety of the existing sensors not all of them are suitable to be integrated in wearables. The application and development of wearables has to consider the characteristics of the p…
Digital communication environments in the workplace
2019
Digital communication environments consist of various kinds of communication technologies and collaboration platforms. These enable employees to communicate through text, audio, video, and graphics, often in an open and networked way. Complementing the popular stand-alone communication tools regularly used in workplaces, such as email and instant messaging, digital communication environments enable the sharing, editing, and storing of information publicly within the organization and sometimes externally among its stakeholders. This chapter reviews and analyzes digital communication environments as well as their affordances and constraints for communication and social interaction in the work…
An Application of Iterative Identification and Control in the Robotics Field
2006
The plant model appropriate for designing the control strongly depends on the requirements. Simple models are enough to compute nondemanding controls. The parameters of well-defined structural models of flexible robot manipulators are difficult to determine because their effect is only visible if the manipulator is under strong actions or with high-frequency excitation. Thus, in this chapter, an iterative approach is suggested. This approach is applied to a one-degree-of-freedom flexible robot manipulator, first using some well-known models and then controlling a lab prototype. This approach can be used with a variety of control design and/or identification techniques.
Examining Sources of Farmers’ Knowledge as a Premise Behind Realization of the Smart Village Conception. A Case Study of Opole Region
2019
The aim of the study is to point to the need of doing research on the system of agricultural knowledge and information as a premise behind realization of the conception of smart village in the territorial framework. Accepting the assumption that intelligent agriculture lies at the foundation of transformation of rural areas, the author indicates the role of the system of agricultural knowledge and information in the process of modernization of agricultural holdings. In the article, questionnaire-based survey research was used in relation to the sustainable development of agriculture in Opole Region. In order to assess the level of adaptation of agricultural holdings to economy based on know…

Orzo da malto, quali varietà scegliere
2015
In generale, il 2015 è stato un anno decisamente diversificato per quanto riguarda le produzioni, ma certamente più favorevole per la coltura dell’orzo primaverile al Centro-Nord, che dopo due anni negativi si riallinea al 2012 con una media produttiva di 5,3 t/ha.
