Using Multivariate Statistics

The measurement of meaning

A wide variety of media can be used in learning, including distance learning, such as print, lectures, conference sections, tutors, pictures, video, sound, and computers. Any one instance of distance learning will make choices among these media, perhaps using several.

An overview of the self-organizing map algorithm, on which the papers in this issue are based, is presented in this article.

The Self-Organizing Map

With digital equipment becoming increasingly networked, either on wired or wireless networks, for personal and professional use alike, distributed software systems have become a crucial element in information and communications technologies. The study of these systems forms the core of the ARLES' work, which is specifically concerned with defining new system software architectures, based on the use of emerging networking technologies. In this context, we concentrate on the study of distributed systems which bring to life the vision of ubiquitous computing systems, also known as ambient intelligence.

This contribution deals with the diagnosis of the quality of transmitted speech. The two current work items approaching this topic of Study Group 12 of the International Telecommunication Union (ITU) are introduced. The first, called P.AMD, is proposed to estimate perceptual quality dimension scores and is in its final steps to become a standard. The second, called P.TCA, identifies technical causes of the transmission channel and recommends a standardized expert annotation methodology which still needs to be validated and improved. For this improvement, this paper presents a systematic approach to process and validate a set of listening material that is suitable for the P.TCA methodology. Motivation for the approach presented here is that former studies showed that the current draft explanations of degradations, which expert listeners are supposed to use for annotation, need improvement. In fact, it was found that it would be best to provide exemplarily listening material together with the P.TCA instructions. For that purpose, this paper describes the processing steps to generate the required example material and presents the results of a validation experiment in which experts annotated the processed speech material according to the P.TCA instructions. The analysis of those annotations reveals that 71% of the example material was labelled correctly. Furthermore, the results suggest to investigate if disagreement of experts can be reduced by modifying the P.TCA annotation procedure as such, or by providing further appropriate example material.

Android applications request specific permissions from users during the installations to perform required functionalities by accessing system resources and personal information. Usually, users must approve the permissions requested by applications (apps) during the installation process and before the apps can collect privacy- or security-relevant information. However, recent studies have shown that users are overwhelmed with the information provided in privacy policies and do not understand permission requests and which functionalities are necessary for certain applications. Hereby, the collection of personal information remains mostly hidden, as the task of verifying to which information different apps have access to can be very complicated. Therefore, it is necessary to develop frameworks and apps that enable the user to perform informed decisions about apps’ run-time permission access to facilitate the control over sensitive information collected by various apps on smartphones. In this work, we conducted an online study with 70 participants who interacted with a mockup app that enables advanced control over permission requests. The selected permissions are based on the apps’ run-time permission access patterns and explanations, and commonly known visual cues are used to facilitate the user’s understanding and privacy-conscious decision making. Furthermore, the effects of perceived control over information sharing and privacy awareness are examined in combination with the permission manager mockup app to investigate if increased control over information sharing increases general privacy awareness. Our results show an interplay between increased control and privacy awareness when explanations and common visual cues are presented to the user. However, the direction of the interplay between increased control and privacy awareness was surprising. Privacy awareness dropped for the experimental group, which received advanced explanations and visual nudges for privacy-conscious decision making. Interestingly privacy awareness significantly increased for the control group, which only received a plain privacy nudge. Therefore, we suggest that increased control over information sharing does not necessarily lead to improved privacy-decision making, and privacy by default might be a more effective design choice.

So far, not much is known on the relationship of quality aspects of multimodal dialog systems. This paper aims at closing this gap by analyzing the influence of input and output modalities on the systems’ usability. The underlying study has been carried out with a smart-home system offering speech, gesture and touch as well as the combination of these three for input and a speech-to-text system, a TV screen and a smartphone screen for output. The results indicate that the usability of a multimodal system is composed of hedonic and pragmatic aspects. The hedonic aspects are influenced by the identity transported by the output channels and the stimulation of the input modalities. A measure for task success was sufficient to describe the pragmatic aspect.

This manuscript explores the development of a technique for detecting the affective states of Virtual Reality (VR) users in real-time. The technique was tested with data from an experiment where 18 participants observed 16 videos with emotional content inside a VR home theater, while their electroencephalography (EEG) signals were recorded. Participants evaluated their affective response toward the videos in terms of a three-dimensional model of affect. Two variants of the technique were analyzed. The difference between both variants was the method used for feature selection. In the first variant, features extracted from the EEG signals were selected using Linear Mixed-Effects (LME) models. In the second variant, features were selected using Recursive Feature Elimination with Cross Validation (RFECV). Random forest was used in both variants to build the classification models. Accuracy, precision, recall and F1 scores were obtained by cross-validation. An ANOVA was conducted to compare the accuracy of the models built in each variant. The results indicate that the feature selection method does not have a significant effect on the accuracy of the classification models. Therefore, both variations (LME and RFECV) seem equally reliable for detecting affective states of VR users. The mean accuracy of the classification models was between 87% and 93%.
