Transfer of training from virtual reality environments

Hamblin, Christopher James 05 1900 (has links)
This study evaluated the transfer of training and training efficiency of two virtual reality environments (head-mounted display and personal computer) for a complex manual assembly task. Transfer of training was measured by comparing the post-training performance of two virtual training groups, a real-world training group and a control group that received no training. All training groups were taught to assemble a Lego(TM) forklift model in their respective environment. After training, participants assembled a real-world model of the forklift as well as a novel model of a racecar, which required the same parts as the forklift assembled in a different configuration. Results from this study show that virtual environments can be effective training simulators for complex assembly tasks although they are less efficient than real-world training. The results also suggest that individual differences such as general intelligence, spatial aptitude, and computer user self-efficacy influence one's ability to learn in a virtual environment. / Thesis (Ph.D.)--Wichita State University, Dept. of Psychology, College of Liberal Arts and Sciences. / "May 2005."

Skilda Världar : Representation av geografiska områden i Danne & Bleckan och Rebecca & Fiona

De Geer, Louis, Wallin Espvall, Jacob January 2012 (has links)
I denna uppsats analyseras realityserierna Rebecca & Fiona samt Danne & Bleckan med syftet att undersöka hur några av de geografiska platser, så som städer, orter och stadsdelar, där dessa serier utspelar sig är representerade. Bägge serierna är gjorda av produktionsbolaget Art89 för SVTs webbkanal SVT-play och sändes mellan 2010 och 2012.De områden som tas upp i analysen är Hornstull, Östermalm, Örebro samt Östberga i Rebecca & Fiona, och Högdalen samt Henriksdalsberget i Danne & Bleckan. Som metod har vi använt en kombination av semiotisk och narrativ analys. Med hjälp av detta har vi tittat på hur serierna konstruerats narratologiskt och vad som konnoteras från det man får se och höra. Detta har gjorts med fokus på de olika områden som serierna i huvudsak utspelar sig i, återkommer till under seriens gång eller får betydelsebärande roll i serien.Uppsatsen utgår från teorier kring genren reality, dess relation med dokumentär film och problematiken kring det sanningsanspråk som finns inom dessa. Vi använder oss även av teorier kring representation, kultur och identitet. Detta för att kunna reflektera kring hur områdens representation bygger på den annorlundahet som finns inom olika kulturer och identiteter.Som jämförelse mot tidigare forskning har vi tittat på rapporten Miljonprogram & Media från 2002 där man har undersökt mediebevakningen kring ett par förorter kring Stockholm sedan 1960-talet. Resultat blev att man har skapat en andrefiering kring människorna och livet i dessa förorter genom att utgå från en normalisering kring “svenskhet”.Resultatet i denna uppsats liknar till viss denna rapport när det kommer till representationen av framförallt Högdalen. Bägge serierna ger en generell bild av att livet för människor är mer avvikande och problematiskt desto längre ifrån de centrala delarna i en större stad man kommer. Serierna skiljer sig åt i att Danne & Bleckan blir mer diskuterande om synen på områdena än vad Rebecca & Fiona är. Den senare utgår nästan uteslutande från huvudkaraktärernas egna åsikter vilket resulterar i att sanningsanspråket som kommer med genren blir den som uttrycks av två subjekt.

A multiscale framework for mixed reality walking tours

Barba, Evan 17 January 2013 (has links)
Mixed Reality experiences, that blend physical and virtual objects, have become commonplace on handheld computing devices. One common application of these technologies is their use in cultural heritage "walking tours." These tours provide information about the surrounding environment in a variety of contexts, to suit the needs and interests of different groups of participants. Using the familiar "campus tour" as a canonical example, this dissertation investigates the technical and cognitive processes involved in transferring this tour from its physical and analog form into Mixed Reality. Using the concept of spatial scale borrowed from cognitive geography, this work identifies the need to create and maintain continuity across different scales of spatial experience as being of paramount importance to successful Mixed Reality walking tours. The concepts of scale transitions, coordination of representations across scales, and scale-matching are shown to be essential to maintaining the continuity of experience. Specific techniques that embody these concepts are also discussed and demonstrated in a number of Mixed Reality examples, including in the context of a successful deployment of a Mixed Reality Tour of the Georgia Tech campus. The potential for a "Language of Mixed Reality" based on the concepts outlined in this work is also discussed, and a general framework, called the Mixed Reality Scale Framework is shown to meet all the necessary criteria for being a cognitive theory of Human-Centered Computing in the context of Mixed Reality.

Development of a Simulator and Training System for Remotely Operated Vehicle Pilots

Hsiao, Yu-hung 28 July 2004 (has links)
The maneuver of ROV requires considerable pilot skill which is a product of physical and mental practice over a long period of time. However, with the limitations of ROV safety, the availability and high cost of deploying equipment, most of ROV pilots gain the necessary skill through on-the-job training. In this study, we developed a simulation system for ROV pilot training and mission planning. This system is implemented in C++ with the cross-platform OpenGL for 3D graphics. It equips with a scene editor allowing the user to build complex 3D geometric objects from simpler primitives. This editor allows the user to change settings of ambient light intensity, visibility, current speed, and seafloor topography for fulfilling specific training requirements. As well, the user can translate and rotate the entire 3D scene and look at it from different vantage point. Besides, this system provides the user with simple commands for mission planning. For realistically simulating the dynamic behavior of the ROV, the nonlinear hydrodynamic equations of motion of the ROV with six degrees of freedom are applied to describe its motion. Moreover, this system is built with the capability of collision detection for evaluating the collision response of ROV. During the training process, the data engine records all navigation data which can be retrieved and played after conducting a training course. The animation playback function exactly reproduces the scenario that occurs during the period of training. It presents the trainee with the opportunity to review the whole operation scenario. Besides, experiments were designed based on the Taguchi Method to study the effects of different factors on ROV pilot performance. The factors selected for evaluation include ROV trajectory display, underwater visibility, ROV positioning error, and current speed. We found that underwater visibility has the greatest influence on ROV pilot performance, next are ROV positioning error and ROV trajectory display, then the current speed. This result will be helpful in rating the level of difficulty of the training.
