Pokémon GO 2016: Exploring Situational Contexts of Critical Incidents in Augmented Reality
2016
Pokémon GO, an augmented reality mobile game, captured the attention of millions of people around the world in July 2016. Various sources from around the globe have reported both positive and negative incidents and outcomes related to the game. Some of the incidents have been particularly remarkable for the player, i.e., critical incidents. A critical incident is a single experience, which a person perceives or remembers as unusually positive or negative. Critical incidents typically are highly influential for human behaviour, and thus, important to study. Playing augmented reality games can take place in varying situational contexts. Situational context includes information that can be use…
Validation and Extension of the Usability Heuristics for Mobile Map Applications
2016
Heuristic usability evaluation is light but efficient method for finding usability problems. In this paper, we report the process of validation and further development of the previously introduced usability heuristics for mobile map applications. The validation began by testing the heuristics by 58 evaluators who used them for usability evaluation of four different map applications. The evaluators also filled a questionnaire about the understandability of the heuristics. The amount, severity and quality of the problems found with the heuristics were reviewed and the heuristics’ understandability analyzed. As a result, it was shown that the heuristics were efficient for finding usability pro…
Lost or not? : designing and evaluating user interfaces of mobile map services : the viewpoint of supporting users' location awareness
2016
The motivation for this thesis arose from the problem of people getting lost, both with and without mobile maps. I will answer a primary research question: 1) How can we support users’ location awareness with mobile map applications? As an ad-dition to this, I have the following sub-questions: a) Why do people get lost even when using a mobile map application? b) What are the best practices to support navigation? c) How can we research what the important objects in the natural environment are that should be emphasized in mobile maps? d) How do we prevent the user from focusing on the map service at the expense of perceiving the location in the real environment? e) What would a good mobile m…
Les modalités iconiques dans le discours médié par ordinateur: du neuf dans l'interaction?
2018
Graphic modalities (emoticons, emoji, GIF…) are often presented as one of the distinctive features of computer-mediated interaction. In what may be the first reference book on computer-mediated communication (also known as CMC), American linguist Susan C. Herring goes as far as calling them a “unique feature” of digital interaction (Herring 1996, 3). Since then, many linguists have tempered this view and shown that graphic modalities are by no means specific to CMC. However, they remain one of its salient features. Are they, then, to be considered as an evolution or a revolution in interaction? The real question is indeed what they bring to computer-mediated communication, and their status …
Ecologists overestimate the importance of predictor variables in model averaging: a plea for cautious interpretations.
2014
Abstract: Information-theory procedures are powerful tools for multimodel inference and are now standard methods in ecology. When performing model averaging on a given set of models, the importance of a predictor variable is commonly estimated by summing the weights of models where the variable appears, the so-called sum of weights (SW). However, SWs have received little methodological attention and are frequently misinterpreted. We assessed the reliability of SW by performing model selection and averaging on simulated data sets including variables strongly and weakly correlated to the response variable and a variable unrelated to the response. Our aim was to investigate how useful SWs are …
Fear of COVID-19 as a buffer in the relationship between perceived stress and life satisfaction in the Polish population at the beginning of the glob…
2020
BackgroundCOVID-19 is a significant threat to human life and health. It makes people experience fear, stress, anxiety and mood disor-ders, which have a negative impact on their psychological well-being. The aim of the study was to determine the relation-ship between fear of COVID-19, perceived stress, and life satisfaction during the coronavirus pandemic.Participants and procedure907 Polish people (522 women and 385 men) participated in this study. The Perceived Stress Scale (PSS-10), the Fear of COVID-19 Scale (FOC-6) and the Satisfaction with Life Scale (SWLS) were used in the study.ResultsFear of COVID-19 and perceived stress were positively correlated with each other and both negatively…
A unifying framework for specifying generalized linear models for categorical data
2013
International audience; In the context of categorical data analysis, the case of nominal and ordinal data has been investigated in depth while the case of partially ordered data has been comparatively neglected. We first propose a new specification of generalized linear models (GLMs) for categorical response variables which en- compasses all the classical models such as multinomial logit, odds proportional or continuation ratio models but also led us to identify new GLMs. This unifying framework makes the different GLMs easier to compare and combine. We then define the more general class of partitioned conditional GLMs for categorical re- sponse variables. This new class enables to take int…
Recursion at the crossroads of sequence modeling, random trees, stochastic algorithms and martingales
2013
This monograph synthesizes several studies spanning from dynamical systems in the statistical analysis of sequences, to analysis of algorithms in random trees and discrete stochastic processes. These works find applications in various fields ranging from biological sequences to linear regression models, branching processes, through functional statistics and estimates of risk indicators for insurances. All the established results use, in one way or another, the recursive property of the structure under study, by highlighting invariants such as martingales, which are at the heart of this monograph, as tools as well as objects of study.
