Dream characteristics in a Brazilian sample: an online survey focusing on lucid dreaming

During sleep, humans experience the offline images and sensations that we call dreams, which are typically emotional and lacking in rational judgment of their bizarreness. However, during lucid dreaming (LD), subjects know that they are dreaming, and may control oneiric content. Dreaming and LD features have been studied in North Americans, Europeans and Asians, but not among Brazilians, the largest population in Latin America. Here we investigated dreams and LD characteristics in a Brazilian sample (n=3,427; median age=25 years) through an online survey. The subjects reported recalling dreams at least once a week (76%), and that dreams typically depicted actions (93%), known people (92%), sounds/voices (78%), and colored images (76%). The oneiric content was associated with plans for the upcoming days (37%), memories of the previous day (13%), or unrelated to the dreamer (30%). Nightmares usually depicted anxiety/fear (65%), being stalked (48%), or other unpleasant sensations(47%). These data corroborate Freudian notion of day residue in dreams, and suggest that dreams and nightmares are simulations of life situations that are related to our psychobiological integrity. Regarding LD, we observed that 77% of the subjects experienced LD at least once in life (44% up to 10 episodes ever), and for 48% LD subjectively lasted less than 1 min. LD frequency correlated weakly with dream recall frequency (r =0.20,p< 0.01), and LD control was rare (29%). LD occurrence was facilitated when subjects did not need to wake up early (38%), a situation that increases rapid eye movement sleep (REMS) duration, or when subjects were under stress (30%), which increases REMS transitions into waking. These results indicate that LD is relatively ubiquitous but rare, unstable, difficult to control, and facilitated by increases in REMS duration and transitions to wake state. Together with LD incidence in USA, Europe and Asia, our data from Latin America strengthen the notion that LD is a general phenomenon of the human species.

Arquitetura para aplicações interativas imersivas de televisão digital

In this work, we propose a new approach to Interactive Digital Television (IDTV), aimed to explore the concepts of immersivity. Several architectures have been proposed to IDTV, but they did not explore coherently questions related to immersion. The goal of this thesis consists in defining formally what is immersion and interactivity for digital TV and how they may be used to improve user experience in this new televisive model. The approach raises questions such as the appropriate choice of equipment to assist in the sense of immersion, which forms of interaction between users can be exploited in the interaction-immersion context, if the environment where an immersive and interactive application is used can influence the user experience, and which new forms of interactivity between users, and interactivity among users and interactive applications can be explored with the use of immersion. As one of the goals of this proposal, we point out new solutions to these issues that require further studies. We intend to formalize the concepts that embrace interactivity in the brazilian system of digital TV. In an initial study, this definition is organized into categories or levels of interactivity. From this point are made analisis and specifications to achieve immersion using DTV. We pretend to make some case studies of immersive interactive applications for digital television in order to validate the proposed architecture. We also approach the use of remote devices anda proposal of middleware architecture that allows its use in conjunction with immersive interactive applications

Marcadores da organização do padrão discursivo narrativo: uma abordagem funcional centrada no uso

This thesis has as its object the Markers Organization Standard Narrative Discourse (MON), from its occurrence in oral and written corpora of different realizations of narrative discourse, considering its locus of occurrence in the narrative and discursive functioning. The research is guided by the Functional Linguistic Usage-Based, approach to which the organization of language is directly linked to the user experience, so that grammar is shaped by discourse. We examined only the narrative portions of Experience Reports, Tales and Legends in the oral and written, as follows: 3 inquiries Corpus Reports Remaining Quilombo (RN); 11 Corpus Legends legends of the Amazon, 14 Tales of Corpus Tales Brazilians and 21 Reports of experiences of Corpus and Discourse Grammar, with about 10,000 words in each corpus. A total of 22 markers were identified, which were: (1) classified according to the locus of occurrence in the narrative structure, as Labov (1972), (2) associated, according to the type of pattern that occur in narrative discourse, (3) described from the discursive function they perform. The research has relevance to the extent it is based speech analysis and offers proposals for productive teaching of mother tongue in which students and teachers can, grounded in language studies, consider living language, as an object of study, based on the National Curriculum Guidelines (OCN) and making use of New Technologies of Information and Communication (NTIC)

Brands Analysis Using Informational Ergonomics Concepts: A Proposal

Currently, a lot of visual information present in all media is form vehemently, for example, in print media and interfaces used for publicity in conjunction with informational design. This visual information has great influence in the life of human beings, since the vision of these individuals is the most used sense. Studies on visual identity have not explored this issue in a satisfactory manner, favoring thus the subject of this small development projects in the area. It is noted the need for analyzes to enable implementation principles of project, making them accessible to the comprehension of most individuals. This study aimed to propose an evaluation of visual identities, which were analyzed by means of visual concepts of usability, design methodologies and Gestalt. We contacted design firms specialized in visual identity projects, places where interviews were conducted to collect the brands allowed for analysis. The results point to a frequent demand for the employment of visual usability principles, design methodologies and Gestalt design in visual identities.

Gamification: applicazioni sociali e mobili

L'obiettivo di questa tesi, in base all'analisi di atti di convegni e workshop, lettura di libri e articoli pubblicati in siti Web, in materie di gamification, è per prima cosa, spiegare il concetto della gamification, partendo da alcune definizioni date da ricercatori e progettisti di videogiochi, cercando di capire sia i fattori positivi, sia i fattori negativi. Si vogliono elencare e spiegare gli elementi di gioco che compongono la gamification, con particolare attenzione alle meccaniche, come punti, distintivi, premi e dinamiche, come competenza, espressione di sè, status sociale, elementi collegati tra di loro, analizzando quali meccaniche originano certe dinamiche. Si cercherà anche di analizzare la gamification sotto gli aspetti psicologici e di User Experience che innescano le motivazioni intrinseche ed estrinseche delle persone, le prime azionate dalle meccaniche, le seconde azionate dalle dinamiche della gamification e l'importanza di ciò nella progettazione di applicazioni gamificate. Si vogliono esaminare ed illustrare in generale, progetti i quali adottano tecniche di gamification, che spaziano dal fitness fino ad attività di marketing per capire i benefici riscontrati. Si vuole inoltre scoprire se ci sono dei validi presupposti per sviluppare App gamificate per smarphone, che sfruttino alcune specifiche tecniche dei dispositivi mobili come, connettività, il GPS ed i sensori come ad esempio, l'accelerometro ed altre tecnologie come il lettore NFC, QR-code. Infine, come caso di studio, saranno testate tre app per smarphone, Foursquare, tramite la quale un utente può consultare e lasciare consigli sui luoghi nelle sue vicinanze, Swarm, tramite la quale un utente oltre ad effettuare il check-in in un luogo, può vedere se ci sono amici nelle vicinanze e Waze, tramite la quale un utente può inviare ed apprendere informazioni relative al traffico.

Immediate Search in the IDE as an Example of Socio-Technical Congruence in Search-Driven Development

Search-driven development is mainly concerned with code reuse but also with code navigation and debugging. In this essay we look at search-driven navigation in the IDE. We consider Smalltalk-80 as an example of a programming system with search-driven navigation capabilities and explore its human factors. We present how immediate search results lead to a user experience of code browsing rather than one of waiting for and clicking through search results. We explore the socio-technical congruence of immediate search, ie unification of tasks and breakpoints with method calls, which leads to simpler and more extensible development tools. Eventually we conclude with remarks on the socio-technical congruence of search-driven development.

Comparison of 2D and 3D GUI Widgets for Stereoscopic Multitouch Setups

Recent developments in the area of interactive entertainment have suggested to combine stereoscopic visualization with multi-touch displays, which has the potential to open up new vistas for natural interaction with interactive three-dimensional (3D) applications. However, the question arises how the user interfaces for system control in such 3D setups should be designed in order to provide an effective user experience. In this article we introduce 3D GUI widgets for interaction with stereoscopic touch displays. The design of the widgets was inspired to skeuomorphism and affordances in such a way that the user should be able to operate the virtual objects in the same way as their real-world equivalents. We evaluate the developed widgets and compared them with their 2D counterparts in the scope of an example application in order to analyze the usability of and user behavior with the widgets. The results reveal differences in user behavior with and without stereoscopic display during touch interaction, and show that the developed 2D as well as 3D GUI widgets can be used effectively in different applications.

Simulating Wind and Warmth in Virtual Reality: Conception, Realization and Evaluation for a CAVE Environment

Wind and warmth sensations proved to be able to enhance users' state of presence in Virtual Reality applications. Still, only few projects deal with their detailed effect on the user and general ways of implementing such stimuli. This work tries to fill this gap: After analyzing requirements for hardware and software concerning wind and warmth simulations, a hardware and also a software setup for the application in a CAVE environment is proposed. The setup is evaluated with regard to technical details and requirements, but also - in the form of a pilot study - in view of user experience and presence. Our setup proved to comply with the requirements and leads to satisfactory results. To our knowledge, the low cost simulation system (approx. 2200 Euro) presented here is one of the most extensive, most flexible and best evaluated systems for creating wind and warmth stimuli in CAVE-based VR applications.
