We investigate the use of laboratory-based methodology for studying participant experience of interactive artworks. The investigation is motivated by two goals: to inform the HCI practitioner of the role of participant experience studies in artwork from the perspective of the artist and to inform the artist of how laboratory-based methodology can contribute to the refinement of their techniques and aesthetics. In this thesis three main purposes for participant experience studies in the artist's process are derived from the roles of artist, art object, and participants in an interactive artwork. Common characteristics of participant experience studies are reviewed, with three cases unique in their use of more formal methodologies examined in detail. This thesis builds on a foundation set forth by these three cases in an investigation of orientation media: media such as text, images, or video designed by the artist to convey supplemental information to participants and thus selectively influence their understanding of different elements in an interactive artwork. Orientation media in the form of instructions cards is used in a study of the interactive sound and video installation piece, Echology. The orientation media is successful in revealing elements of the artwork that, given explicit instructions or not, still cause confusion among participants. A general review of the study methodology is also provided. This includes observations of changes in participant behaviour due to their roles as subjects in a study and implications these changes have on using formal methodologies for studying participant experience.

We describe a semi-automatic technique for modeling and animating complex musculoskeletal systems using a strand based muscle model. Using our interactive tools, we are able to generate the motion of tendons and muscles under the skin of a traditionally animated character. This is achieved by integrating the traditional animation pipeline with a biomechanical simulator capable of dynamic simulation with complex routing constraints on muscles and tendons. We integrate our musculoskeletal modeling and animation toolkit into a professional 3D production environment, thereby enabling artists and scientists to create complex musculoskeletal systems that were previously inaccessible to them. We demonstrate the applications of our tools to the visual effects industry with several animations of the human hand and applications to the biomechanics community with a novel model of the human shoulder.

Most interaction with computers today takes place in a two dimensional environment. Even when using three dimensional graphics applications, input is often still restricted to two dimensions. Many believe that the use of three dimensional input devices will alleviate this restriction and allow for a much more natural human-machine dialog. This thesis seeks to establish how factors dealing with visual feedback and task structure affect the ability to perform interactive tasks in a three dimensional virtual environment. The factors investigated were stereoscopic vision, motion parallax, stimulus arrangement and stimulus complexity. Four tasks were studied. These tasks were: point location, docking, line tracing and curve tracing. All the tasks used a six degree of freedom input device to control a pointer in a three dimensional virtual environment. Four experiments corresponding to the four tasks were conducted to investigate these factors. Among other things the results showed the following. Stereoscopic vision provided a strong benefit to positioning-based tasks, but this benefit was weakened in the case of tracing tasks. Motion parallax via head-tracking often had no effect upon task performance and where an effect was found it was often detrimental. The position of stimuli influenced performance across all of the tasks. The orientation of stimuli influenced performance in the task in which it was varied.

Since McClelland and Rumelhart (1981) introduced the concept of interactive activation (IA) to the field of visual word recognition, IA has been adopted by all of the major theoretical models of reading aloud. This widespread adoption of IA has not been met with a close examination of the need for the principle features of this processing approach. In particular, IA assumes feedback from later processing modules to earlier processing modules. Though there exist data that can be explained by such feedback mechanisms, and indeed IA may be an intuitive approach to complex tasks like reading, little effort has been made to explain these same phenomena without feedback. In the present study I apply Occam’s razor to the most successful model of reading aloud (CDP+; Perry, Ziegler, & Zorzi, 2007) and test whether feedback is needed to simulate any of the benchmark phenomena identified by Perry et al. (2007) and Coltheart, Rastle, Perry, Langdon and Ziegler (2001). I find that the data currently do not require any feedback mechanisms in reading aloud, and thus conclude that modelers in reading aloud have been too quick to adopt the principles of IA.
