Abstract / Description
The purpose of this thesis is to explore how surface engagement through touch affects perception of stimuli and mood. Researchers have found psychological, physiological and cognitive benefits associated with exposure to and interaction with nature. Stress Reduction Theory with Psychoevolutionary framework, and Attention Restoration Theory are often used to explain and interpret results.

Show moreThe purpose of this thesis is to explore how surface engagement through touch affects perception of stimuli and mood. Researchers have found psychological, physiological and cognitive benefits associated with exposure to and interaction with nature. Stress Reduction Theory with Psychoevolutionary framework, and Attention Restoration Theory are often used to explain and interpret results. However, studies that focus on individuals with negative perspectives of nature find a positive affective response to nature is not universal. Rather, individuals respond differently based on their own experience with nature. Childhood exposure and culture have been found to influence attitudes towards nature. Theories of embodied cognition emphasize the importance of previously learned associations and embodied states have been found to influence judgment, experience of emotions, and physiological states. To assess whether an individual's attitude towards nature influences the embodiment of a positive or negative state, participants were randomly assigned to come into physical contact with one of four surfaces with their feet: grass, fake grass, dirt and cement. Individuals affective, cognitive and physical relationship with nature was measured with the Nature Relatedness Scale. Change in perception of neutral stimuli and mood before and after surface exposure were measured. Results suggested surfaces influenced mood in different ways, however the effects on perception were unclear. A participant's perspective of nature did not seem to influence mood change depending on surface type. Future research is needed to assess whether the shift in mood was based on metaphors of language, priming from surface texture, or a result of complex interaction between bodily sensations and cognition.

While works in literature are ripe with descriptions of attempts at producing viable ECA architectures, few authors have addressed the role of episodic memory models in conversational agents.

Show moreEmbodied Conversational Agents (ECA) form part of a range of virtual characters whose intended purpose include engaging in natural conversations with human users. While works in literature are ripe with descriptions of attempts at producing viable ECA architectures, few authors have addressed the role of episodic memory models in conversational agents. This form of memory, which provides a sense of autobiographic record-keeping in humans, has only recently been peripherally integrated into dialog management tools for ECAs. In our work, we propose to take a closer look at the shared characteristics of episodic memory models in recent examples from the field. Additionally, we propose several enhancements to these existing models through a unified episodic memory model for ECAÂÂ's. As part of our research into episodic memory models, we present a process for determining the prevalent contexts in the conversations obtained from the aforementioned interactions. The process presented demonstrates the use of statistical and machine learning services, as well as Natural Language Processing techniques to extract relevant snippets from conversations. Finally, mechanisms to store, retrieve, and recall episodes from previous conversations are discussed. A primary contribution of this research is in the context of contemporary memory models for conversational agents and cognitive architectures. To the best of our knowledge, this is the first attempt at providing a comparative summary of existing works. As implementations of ECAs become more complex and encompass more realistic conversation engines, we expect that episodic memory models will continue to evolve and further enhance the naturalness of conversations.

SketChart: A Pen-Based Tool for Chart Generation and Interaction.

SketChart: A Pen-Based Tool for Chart Generation and Interaction.
Creator
Vargas Gonzalez, Andres, Laviola II, Joseph, Foroosh, Hassan, Hua, Kien, University of Central Florida
Abstract / Description
It has been shown that representing data with the right visualization increases the understanding of qualitative and quantitative information encoded in documents. However, current tools for generating such visualizations involve the use of traditional WIMP techniques, which perhaps makes free interaction and direct manipulation of the content harder.

Show moreIt has been shown that representing data with the right visualization increases the understanding of qualitative and quantitative information encoded in documents. However, current tools for generating such visualizations involve the use of traditional WIMP techniques, which perhaps makes free interaction and direct manipulation of the content harder. In this thesis, we present a pen-based prototype for data visualization using 10 different types of bar based charts. The prototype lets users sketch a chart and interact with the information once the drawing is identified. The prototype's user interface consists of an area to sketch and touch based elements that will be displayed depending on the context and nature of the outline. Brainstorming and live presentations can benefit from the prototype due to the ability to visualize and manipulate data in real time. We also perform a short, informal user study to measure effectiveness of the tool while recognizing sketches and users acceptance while interacting with the system. Results show SketChart strengths and weaknesses and areas for improvement.

Show moreLegends of the Fabricated Wild is a feature-length body of work of landscape films. Voice-Destroy, Self-Portrait: Impermanence and the titular Legends of the Fabricated Wild are the experimental films that comprise my body of work. Keep your Distance, a single-channel installation, is a supplemental piece.Legends of the Fabricated Wild frames the complex interaction between a filmmaker and the collective unconsciousness of the natural environment, a theory outlined by Carl Jung, considering the implications and discoveries along the way. Subtle movement and precise compositions provide a transcendental perspective on the natural Florida landscape. Images of landscapes devoid of human figures are structured together in my work to meditate on the environment and the way humanity has shaped the landscape. Super 8mm and 16mm analog film frames expansive landscapes in a square image and challenges modern cinematic representations by applying the texture of celluloid. High definition digital video contrasts analog film. I foreground artificiality and the ways humanity has utilized the landscape through this medium.While searching for places to document (")pure(") or untouched landscapes, I discovered that modern landscapes are always influenced by the exchange between humanity and the natural environment. I wanted to foreground my own interaction with the natural Florida environment and challenge my interests and dominant ways of viewing landscapes. Through the assembly of a cinematic essay of landscape images with subtle motion, I foster an appreciation for the natural environment in an age of hyper-activity and exploitation of the landscape.
