This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.

This research thesis is an exploration into what possibilities lie beyond the representation of analog material when it transcends into the digital realm. Specifically, how printed comics can be altered in realtime by creator- allowed user interaction, when adapted for presentation within the digital sphere of mobile smartphones and computer tablets. Using legacy computer-game techniques like parallax scrolling with modern digital layer filters, device sensors and applying them in realtime to the comic creators digitally layered content, alternative forms of presentation arise.This is an investigation into the comic creator’s will of allowing possibilities of added depth perception, interactivity and alternative visual narratives in their comic, manga or graphic novels when employing new techniques based on sensor data input from a reader, like accelerometer-, gyroscope- or eye-tracking sensors. Several different techniques are evaluated. The focus is mainly on the context of creators of comics or manga who use digital tools and layer compositions when producing their work. Several aspects of the user-centered experience are also explored.Although mainly an interaction design project, most of the design methods are used from a service design approach, emphasizing co-design techniques like interviews, observations and user tests. The results are digital prototypes and proof-of-concepts featuring technology tests that support final design conclusions.The results will show both enthusiasm and reluctance from test subjects towards the new technologies presented. The professional craft of comic, manga and graphic novel creation has a deeply rooted aesthetic and production cycle in its history of the printed form. It could be difficult to alter its standard, reverence and nostalgia in the eyes of its readers and creators, when pursuing the digital format and narrative possibilities of the future. A video explaining the project’s “Drawn To Life” technology is available online.

Age-related physical and cognitive changes hinder the ability of older adults to operate smartphones. While many user interface (UI) heuristics exist today, there is a need for an updated set designed specifically to assess the usability of mobile devices for an older audience. Smartphone evaluation heuristics for older adults based on age-related changes in vision, hearing, attention, memory and motor control were developed in this thesis by analyzing literature on age-related physical and cognitive changes impacting smartphone usability. Support for heuristics was found by gathering information on how older adults use cell phones through interviews and an online survey. It was demonstrated that strength of support for some heuristics increases with age. The evaluated heuristics provide usability practitioners and designers with a framework for evaluating the usability of smartphones for older adults.

The aim of this thesis was to develop a touchscreen-adapted version of the well established Keystroke-level model, which is a user performance model designed to be a quick and easy way to evaluate user interfaces prior to creating prototypes. A quantitative research method was chosen to measure general execution times for common touchscreen gestures on mobile devices. Over 1000 data points were collected from participants who partook in a observational experiment using a prototype specifically programmed for this study. The results of the thesis involves the analyzed measurements acquired from the experiment, as well as a four important aspect to consider when performing similar experiments, namely: (1) The individual speed of the participants; (2) The participants’ level of expertise; (3) The participants’ methods of performing the gestures; (4) Designing the experiment for medium difficulty. / Målet med denna uppsats var att utveckla en pekskärmsanpassad version av den välkända modellen Keystroke-level model, vilket är en modell som kan användas för att snabbt och enkelt utvärdera gränssnitt utan att behöva utveckla fungerande prototyper. En kvantitativ forskningsmetod användes för att mäta hur lång tid det tar för användare generellt att utföra de vanligaste fingergesterna på mobila pekskärmar. Över 1000 datapunkter samlades in från ett experiment där deltagarna fick använda en prototyp som automatiskt mätte den tid det tog för användarna att utföra de olika fingergesterna. Resultaten av studien består av de mätvärden som räknats ut samt fyra aspekter som är viktiga att ha i beaktning när liknande experiment ska utformas. Dessa är: (1) Varje deltagares individuella hastighet; (2) Deltagarnas pekskärmsvana; (3) Sättet de olika deltagarna utför fingergesterna; (4) Utforma experimentet för att representera en medium svårighetsgrad. / Le but de ce projet fut de créer une version du Keystroke-level model adaptée aux écrans tactiles. Ce modèle de performance utilisateur est une méthode d’évaluation simple et rapide d’interfaces utilisateur avant la création de prototypes. Une étude quantitative fut choisie pour mesurer le temps d’exécution général de mouvements spécifiques effectués sur des écrans tactiles de téléphones. Plus de 1000 points de données furent collectés auprès de participants ayant pris part à une étude observationnelle utilisant un prototype spécialement programmé pour l’occasion. Les résultats de ce projet incluent l’analyse des mesures acquises lors de cette étude ainsi que quatre aspects importants à considérer lors de la réalisation d’études similaires, à savoir: (1) La vitesse individuelle des participants; (2) Le niveau d’habitude d’utilisation d’écrans tactiles des participants; (3) Les méthodes utilisées par les participants lors de la réalisation des mouvements; (4) La conception d’étude pour des mouvements de difficulté dite moyenne.

L’essor du numérique et la multiplication des supports (smartphone, tablette tactile)ouvrent de nouvelles perspectives en matière d’écriture. Dans ce monde où textes, images et sons s’entrecroisent au fil des réseaux et au gré de l’interactivité, la fiction littéraire peut-elle trouver une voie qui lui permette de préserver sa richesse tout en bénéficiant des apports du numérique ? Comment l’auteur littéraire peut-il concevoir et agencer ses matériaux narratifs afin de toucher efficacement des lecteurs disposés à franchir le pas du numérique ? Quels sont les fondements d’une narration multimodale utilisant au mieux les potentiels du texte, de l’image et du son, dans toute leur complémentarité, pour servir une fiction littéraire destinée à un large public ? Ces questions sont abordées, tant du point de vue de l’auteur que de celui du lecteur, dans une approche transdisciplinaire à la fois théorique et expérimentale. / The intense development of digital technologies and hardware (smartphones, tablets) is opening up new prospects for storytelling. In a world where texts, images and sound intermingle through networks and user interactivity, is it possible for narrative fiction to preserve its great wealth while taking advantage of digital techniques? How can a literary author put together and elaborate his narrative components to effectively reach readers willing to use digital content? What are the foundations of multimodal storytelling that use all the potential of text, image and sound in the best complementary ways to create narrative fiction that can be read by a large public? What balances can be found between "telling" and"showing"? How can interactivity be used to serve the narrative without losing the reader? These issues will be dealt with from both the author's and reader's point of view, in an interdisciplinary approach mixing theory and experimentation.

Pekskärmar används i allt större utsträckning som interaktionsteknik för hemelektronik. Tekniken har traditionellt sett inte använts i krävande miljöer, exempelvis i miljöer där skakningar och g-laster förekommer. Introduktionen av pekskärmsteknologi i cockpitmiljö får konsekvenser för utformningen av förarmiljön vilka bör utredas. Denna studie syftade till att empiriskt utvärdera användarnas prestation med avseende på precision vid olika interaktionsmanövrar på en pekskärm. Fyra försök genomfördes med 14 försöksdeltagare i en simulerad miljö där olika grader av skakningar förekom. Precisionsmätningar genomfördes i samband med försöken och försöksdeltagarnas subjektivt upplevda arbetsbelastning mättes med hjälp av NASAs självskattningsformulär för upplevd arbetsbelastning (TLX). Korrelationsanalyser genomfördes mellan försöksdeltagarnas subjektiva arbetsbelastning och data från försöken. Det genomfördes också differensanalyser mellan försökens olika betingelser för att se om det förekom någon inlärningseffekt. Testresultaten visar att relativt god precision går att uppnå vid interaktion med pekskärm men att vissa typer av interaktion är svårare och skattas högre med avseende på arbetsbelastning än andra. Resultatet från en inledande workshop med förare och ingenjörer visar på en positiv inställning till pekskärmar som komplement till inmatning i cockpit. Rapporten ger rekommendationer för utformningen av gränssnitt för pekskärm för att undvika interaktionsproblem vid skakningar och g-laster. / Touchscreens are a common occurrence in everyday applications these days. The technology is not traditionally used in high hazard environments, in example where vibrations and G-forces is frequently occurring. The consequences of introducing touchscreens to the cockpit environment are something to consider when designing the pilot environment.   The purpose of this study is to empirically evaluate the user performance and precision when interacting with touchscreens. Four tests were conducted with 14 trial participants in a semi-controlled environment where varying degrees of vibrations occurred. Measurements of the participants’ precision were measured together with a subjective workload measure developed by NASA (TLX).  Correlation analyses were carried out between the experimental participants’ subjective workload and data from the experiments.  The difference in precision and performance was also analysed between the precision tests to see if there was any learning effects.   The test results show that good precision was possible to some extent but that some types of interaction is more difficult then others hence increasing workload for the participants.  The results of an initial workshop with pilots and engineers show a positive attitude towards touchscreens as complement for the currently available input methods. The report provides recommendations for the design of touchscreen interfaces to avoid issues caused by shaking and g-loads.
