Multimedia technology enables direct manipulation of multiple media such as text, image, audio, and video, all integrated into one entity - the multimedia document. Interactive multimedia documents integrate text, images and continuous media such as audio and video, treat them as objects to be presented for a certain duration, and allow users to interact with the presentation. Authoring and presenting interactive multimedia documents imposes new requirements on document representation. We designed the interactive timeline model (ITM) for authoring and presenting interactive multimedia documents. We implemented the model and created a playback tool using the scripting language Tel. ITM uses an enhanced timeline model for representing interactive multimedia scenarios. ITM is a layered model that supports the creation of the logical, temporal, and presentation structures of a multimedia document and emphasizes the separation of content from its structure. The storage layer provides interfaces for creation and storage of media objects like text, images, scripts, choices, and audio. Choice is a media object that allows users to interact with the presentation. A script object causes Tel code to be executed. The composition layer specifies the logical structure and provides interfaces to compose a multimedia document. The presentation layer specifies the temporal and spatial structure of the document and describes the user interface for the playback tool. The run-time layer specifies the interfaces to start and control the flow of the presentation, describes the possible interactions between a user and the presentation at run-time, and specifies the actions to be taken when interaction takes place. ITM allows users to configure the playback tool according to their needs. It provides authors with a mechanism to create new interfaces and register them with the playback tool. To evaluate the design decisions of ITM and verify its usability, we conducted usability tests on the model. We asked a representative sample of end users ( both authors and viewers) to perform realistic tasks using the model. ITM is a powerful model to create and present interactive learning materials and dynamic presentations.

abstract: Parkinson's disease (PD) is a neurodegenerative disorder that produces a characteristic set of neuromotor deficits that sometimes includes reduced amplitude and velocity of movement. Several studies have shown that people with PD improved their motor performance when presented with external cues. Other work has demonstrated that high velocity and large amplitude exercises can increase the amplitude and velocity of movement in simple carryover tasks in the upper and lower extremities. Although the cause for these effects is not known, improvements due to cueing suggest that part of the neuromotor deficit in PD is in the integration of sensory feedback to produce motor commands. Previous studies have documented some somatosensory deficits, but only limited information is available regarding the nature and magnitude of sensorimotor deficits in the shoulder of people with PD. The goals of this research were to characterize the sensorimotor impairment in the shoulder joint of people with PD and to investigate the use of visual feedback and large amplitude/high velocity exercises to target PD-related motor deficits. Two systems were designed and developed to use visual feedback to assess the ability of participants to accurately adjust limb placement or limb movement velocity and to encourage improvements in performance of these tasks. Each system was tested on participants with PD, age-matched control subjects and young control subjects to characterize and compare limb placement and velocity control capabilities. Results demonstrated that participants with PD were less accurate at placing their limbs than age-matched or young control subjects, but that their performance improved over the course of the test session such that by the end, the participants with PD performed as well as controls. For the limb velocity feedback task, participants with PD and age-matched control subjects were less accurate than young control subjects, but at the end of the session, participants with PD and age-matched control subjects were as accurate as the young control subjects. This study demonstrates that people with PD were able to improve their movement patterns based on visual feedback of performance and suggests that this feedback paradigm may be useful in exercise programs for people with PD. / Dissertation/Thesis / Doctoral Dissertation Bioengineering 2015

abstract: The current study investigated how multimedia pacing (learner-control versus system-paced) and presentation styles (visual-only versus audio/visual) impact learning physics concept material, mental effort, and self-efficacy. This 2X2 factorial study randomly assigned participants into one of four conditions that manipulated presentation style (visual-only versus audio/visual) and pacing of the content (system-paced versus learning-controlled). Participant's learning was measured by recording their retention of information and ability to transfer information. Measures of perceived difficulty (mental effort) and perceived ability (self-efficacy) were also obtained. No significant effects were observed in this study which doesn’t support the existence of either the modality or reverse modality effect at least in these noisier online learning environments. In addition, the hypothesis that their effects could be an artifact of experimental design could not be proven as the learner control condition did not yield any significant results. / Dissertation/Thesis / Masters Thesis Human Systems Engineering 2018

Syftet med föreliggande studie är att bidra med ökad kunskap om e-lärande i arbetslivet. E-lärande har i föreliggande studie definierats i enlighet med Clark och Mayers (2016) som; ”instruktion levererad på en digital enhet och som är menad att främja lärandet [egen översättning]” (2016, s. 38). Emellertid har studien valt att begränsa sig till endast dator som digital enhet. Föreliggande studie belyser även multimedia inom e-lärande som relevant då multimedia utgör en vital del av e-lärande. För att besvara studiens syfte användes två frågeställningar för att undersöka; (1) medarbetares upplevelse av e-lärande och (2) medarbetares upplevelse av multimedia inom e-lärande. Båda inom kontexten för arbetsplatslärande. Baserat på studiens syfte valdes en kvalitativ ansats där studiens material har bestått av semistrukturerade intervjuer med medarbetare inom den offentliga sektorn. Materialet har utifrån teoretiska begrepp och utgångspunkter bearbetats och analyserats genom en tematisk analys. Resultatet påvisade att vilka delar och hur delarna var utformade påverkar medarbetares upplevelse av e-lärande på arbetsplatsen. Resultatet tydde på att syftet med e-lärandet, tidsuppfattningen av e-lärande och vilken typ av kommunikation som inkluderades hade påverkan på medarbetares upplevelse av e-lärande på arbetsplatsen. Vidare visar resultatet att ett inkluderande av multimedia är en främjande faktor för lärandet vilket påvisar dess påverkan på medarbetares upplevelse av multimedia inom e-lärande. Emellertid tyder resultatet på att för mycket information som presenteras genom multimedia är hämmande för lärandet och således påverkar även det medarbetares upplevelse av multimedia inom e-lärande. / The purpose of this study has been to contribute with increased knowledge about e-learning in workplaces. E-learning have in this study been defined as “instruction delivered on a digital device (such as a desktop computer, laptop computer, tablet, or smartphone) that is intended to support learning” (Clark & Mayer, 2016, s. 38) which is in accordance with the definition by Clark and Mayers (2016). However, this study chosen to limit the definition too only include computer as the digital device. Multimedia can be seen as an important part of e-learning and therefore multimedia has been included in this study. In order for the study to serve its purpose two separate research question has been defined to examine; (1) employee’s experience of e-learning and (2) employee’s experience of multimedia in e-learning. Both in the context of workplace learning. Based on the purpose of the study a qualitative method has been chosen and the research materials have consisted of semi-structured interviews with employees in the public sector. Based on the study’s theoretical framework, the research materials have been analyzed through a thematic analysis. The presented result shows that employee’s experience of e-learning is affected by which component of e-learning and the content of the components of e-learning is used. It’s shown that the purpose of e-learning, time and the ability to collaborate with others are key components of e-learning. Furthermore, including multimedia is enhancing for learning which indicates its effect on the employee’s experience of multimedia in e-learning. However, the results indicate that too much information presented through multimedia can impede the learning and therefore the employee’s experience of multimedia in e-learning is affected by the amount of information presented.

abstract: The utilization of multimedia videos has increasingly become more popular, especially in the field of education. In order to facilitate learning it is important to create a natural interaction between the learner and the on-screen material. This study focused on improving the facilitation of the information within a multimedia learning video by focusing on the gender and quality of computer-synthesized voices. Using a randomized pretest - posttest design the study looked at how the gender of the narrator affected a person's ability to learn and implement a new task. Narration was performed by a male and female, classic and modern synthesized voices to determine if there were gender effects across both generations of voices. The participants’ learned knowledge was assessed through a multiple-choice assessment and a word to image matching transfer assessment. Results showed no significant results. Future studies should consider a more reliable knowledge assessment and utilize and larger sample size. / Dissertation/Thesis / Masters Thesis Human Systems Engineering 2019
