Abstract / Description
State-of-the-art domestic robot assistants are essentially autonomous mobile manipulators capable of exerting human-scale precision grasps. To maximize utility and economy, non-technical end-users would need to be nearly as efficient as trained roboticists in control and collaboration of manipulation task behaviors. However, it remains a significant challenge given that many WIMP-style tools require superficial proficiency in robotics, 3D graphics, and computer science for rapid task modeling...
Show moreState-of-the-art domestic robot assistants are essentially autonomous mobile manipulators capable of exerting human-scale precision grasps. To maximize utility and economy, non-technical end-users would need to be nearly as efficient as trained roboticists in control and collaboration of manipulation task behaviors. However, it remains a significant challenge given that many WIMP-style tools require superficial proficiency in robotics, 3D graphics, and computer science for rapid task modeling and recovery. But research on robot-centric collaboration has garnered momentum in recent years; robots are now planning in partially observable environments that maintain geometries and semantic maps, presenting opportunities for non-experts to cooperatively control task behavior with autonomous-planning agents exploiting the knowledge. However, as autonomous systems are not immune to errors under perceptual difficulty, a human-in-the-loop is needed to bias autonomous-planning towards recovery conditions that resume the task and avoid similar errors.In this work, we explore interactive techniques allowing non-technical users to model task behaviors and perceive cooperatively with a service robot under robot-centric collaboration. We evaluate stylus and touch modalities that users can intuitively and effectively convey natural abstractions of high-level tasks, semantic revisions, and geometries about the world. Experiments are conducted with `pick-and-place' tasks in an ideal `Blocks World' environment using a Kinova JACO six degree-of-freedom manipulator. Possibilities for the architecture and interface are demonstrated with the following features; (1) Semantic `Object' and `Location' grounding that describe function and ambiguous geometries (2) Task specification with an unordered list of goal predicates, and (3) Guiding task recovery with implied scene geometries and trajectory via symmetry cues and configuration space abstraction. Empirical results from four user studies show our interface was much preferred than the control condition, demonstrating high learnability and ease-of-use that enable our non-technical participants to model complex tasks, provide effective recovery assistance, and teleoperative control.

Creator
Silva, Pedro, Kim, Si Jung, Lindgren, Robb, McDaniel, Thomas, University of Central Florida
Abstract / Description
This thesis explored the application of Media Synchronicity Theory and its potential for translating Critical Pedagogy (specifically Boal's Theatre of the Oppressed) into a computer- supported collaborative work (CSCW) environment. It introduces the Maquina dos Oprimidos (Mados) prototype, a CSCW supplement to traditional asynchronous learning networks. Mados operates as a role-playing debate game, in which students debate a pre-selected prompt while performing assigned character roles. The...
Show moreThis thesis explored the application of Media Synchronicity Theory and its potential for translating Critical Pedagogy (specifically Boal's Theatre of the Oppressed) into a computer- supported collaborative work (CSCW) environment. It introduces the Maquina dos Oprimidos (Mados) prototype, a CSCW supplement to traditional asynchronous learning networks. Mados operates as a role-playing debate game, in which students debate a pre-selected prompt while performing assigned character roles. The study explores the prototype's potential to affect student's identification with their assigned character and personal attitude toward the prompt, as well as examining the effect of presence on students' performances.The study was performed with 38 8th grade students. Subjects debated a prompt which proposed a banning cell phones from classrooms. Results show that subjects collaboratively constructed solutions that compromised between both positions, while slightly favoring the anti- ban position. Results also show that subjects experienced gains in character identification after participating in the task regardless of assigned character, hinting at a separation between perceived similarity to characters and affinity for characters' position. The ability of subjects to defend their assigned character's position while inhabiting their own perspective, that of an 8th grade student, also hints at this separation. Additionally, results indicated correlations between subjects' control factors, a subset measure for presence, and total change in prompt agreement. Other positive correlation exist between subject's reprocessing attempts and task performance, as well as total presence and task performance.

Show moreWhen discussing games and the experience of gamers those with disabilities are often overlooked. This has left a gap in our understanding of the experience of players with disabilities in virtual game worlds. However there are examples of players with disabilities being very successful in the virtual world video game World of Warcraft, suggesting that there is an opportunity to study the game for usability insight in creating other virtual world environments. This study surveyed World of Warcraft players with disabilities online for insight into how they used interface addons to manage their experience and identity performance in the game. A rubric was also created to study a selection of addons for evidence of the principles of Universal Design for Learning (UDL). The study found that World of Warcraft players with disabilities do not use addons more than able-bodied players, but some of the most popular addons do exhibit many or most of the principles of UDL. UDL principles appear to have emerged organically from addon iterations over time. The study concludes by suggesting that the same approach to user-generated content for the game interface taken by the creators of World of Warcraft, as well as high user investment in the environment, can lead to more accessible virtual world learning environments in the future.

Show moreThe objective of this thesis is to investigate the history of interactive videos and examine some possible reasons as to why they have never been successful. Because the method of interactivity is often disrupting to the narrative, I wanted to make something that was much more fluid. To this end, I produced Man Alone Interactive, a branching story that allows users to choose their path without stopping the narrative.The purpose for creating it was to see if a different interactive mechanic would aid in the user immersion. In order to fully test this, two versions of the movie were created. One with the relatively standard interactive technique of stopping the story to display the choices and another that had the choices onscreen as the video progressed. The two versions were then used in a study to determine which was more engaging to users. This paper examines the research that led to the design, the process by which the story and different versions were created and the results of the study.

Show moreGAYME is a transmedia story-telling world that I have created to conceptually explore the dynamics of queering game design through the development of varying game prototypes. The final iteration of GAYME is @deadquarewalking*. It is a documentary game and a performance art installation that documents a carless, gay/queer/quare man's journey on Halloween to get to and from one of Orlando's most well-known gay clubs - the Parliament House Resort. "The art of cruising" city streets to seek out queer/quare companionship particularly amongst gay, male culture(s) is well-documented in densely, populated cities like New York, San Francisco and London, but not so much in car-centric, urban environments like Orlando that are less oriented towards pedestrians. Cruising has been and continues to be risky even in pedestrian-friendly cities but in Orlando cruising takes on a whole other dimension of danger. In 2011-2012, The Advocate magazine named Orlando one of the gayest cities in America (Breen, 2012). Transportation for America (2011) also named the Orlando metropolitan region the most dangerous city in the country for pedestrians. Living in Orlando without a car can be deadly as well as a significant barrier to connecting with other people, especially queer/quare people, because of Orlando's car-centric design. In Orlando, cars are sexy. At the same time, the increasing prevalence in gay, male culture(s) of geo-social, mobile phone applications using Global Positioning Systems (GPS) and location aware services, such as Grindr (Grindr, LLC., 2009) and even FourSquare (Crowley and Selvadurai, 2009) and Instagram (Systrom and Krieger, 2010), is shifting the way gay/queer/quare Orlandoans co-create social and sexual networks both online and offline. Urban and sub-urban landscapes have transformed into hybrid "techno-scapes" overlaying "the electronic, the emotional and the social with the geographic and the physical" (Hjorth, 2011). With or without a car, gay men can still geo-socially cruise Orlando's car-centric, street life with mobile devices. As such emerging media has become more pervasive, it has created new opportunities to quarely visualize Orlando's "technoscape" through phone photography and hashtag metadata while also blurring lines between the artist and the curator, the player and the game designer.This project particularly has evolved to employ game design as an exhibition tool for the visualization of geo-social photography through hashtag play. Using hashtags as a game mechanic generates metadata that potentially identifies patterns of play and "ways of seeing" across player experiences as they attempt to make meaning of the images they encounter in the game. @deadquarewalking also demonstrates the potential of game design and geo-social, photo-sharing applications to illuminate new ways of documenting and witnessing the urban landscapes that we both collectively and uniquely inhabit.*In Irish culture, (")quare(") can mean (")very(") or (")extremely(") or it can be a spelling of the rural or Southern pronunciation of the word (")queer.(") Living in the American Southeast, I personally relate more to the term (")quare(") versus (")queer.(") Cultural theorist E. Patrick Johnson (2001) also argues for (")quareness(") as a way to question the subjective bias of whiteness in queer studies that risks discounting the lived experiences and material realities of people of color. Though I do not identify as a person of color and would be categorized as white or European American, (")quareness(") has an important critical application for considering how Orlando's urban design is intersectionally racialized, gendered and classed.
