Mason, Andrea H., Walji, Masuma A., Lee, Elaine J. and MacKenzie, Christine L. (2001): Reaching Movements to Augmented and Graphic Objects in Virtual Environments. In: Beaudouin-Lafon, Michel and Jacob, Robert J. K. (eds.) Proceedings of the ACM CHI 2001 Human Factors in Computing Systems Conference March 31 - April 5, 2001, Seattle, Washington, USA. pp. 426-433. Available online

“This work explores how the availability of visual and haptic feedback affects and kinematics of reaching performance in a tabletop virtual environment. Eight subjects performed reach-to-grasp movements toward target objects of various sites in conditions where visual and haptic feedback were either present or absent. It was found that movement time was slower when visual feedback of the moving limb was not available. Further MT varied systematically with target size when haptic feedback was available (i.e. augmented targets), and thus followed Fitts' law. However, movement times were constant regardless of target size when haptic feedback was removed. In depth analysis of the reaching kinematics revealed that subjects spent longer decelerating toward smaller targets in conditions where haptic feedback was available. In contrast, deceleration time was constant when haptic feedback was absent. These results suggest that visual feedback about the moving limb and veridical haptic feedback about object contract are extremely important for humans to effectively work in virtual environments.”

Wang, Yanqing and MacKenzie, Christine L. (2000): The Role of Contextual Haptic and Visual Constraints on Object Manipulation in Virtual Environments. In: Turner, Thea, Szwillus, Gerd, Czerwinski, Mary, Peterno, Fabio and Pemberton, Steven (eds.) Proceedings of the ACM CHI 2000 Human Factors in Computing Systems Conference April 1-6, 2000, The Hague, The Netherlands. pp. 532-539. Available online

“An experiment was conducted to investigate the role of surrounding haptic and visual information on object manipulation in a virtual environment. The contextual haptic constraints were implemented with a physical table and the contextual visual constraints included a checkerboard background ("virtual table"). It was found that the contextual haptic constraints (the physical table surface) dramatically increased object manipulation speed, but slightly reduced spatial accuracy, compared to free space. The contextual visual constraints (presence of the checkerboard) actually showed detrimental effects on both object manipulation speed and accuracy. Implications of these findings for human-computer interaction design are discussed.”

Wang, Yancling and MacKenzie, Christine L. (1999): Object Manipulation in Virtual Environments: Relative Size Matters. In: Altom, Mark W. and Williams, Marian G. (eds.) Proceedings of the ACM CHI 99 Human Factors in Computing Systems Conference May 15-20, 1999, Pittsburgh, Pennsylvania. pp. 48-55. Available online

“An experiment was conducted to systematically investigate combined effects of controller, cursor and target size on multidimensional object manipulation in a virtual environment. It was found that it was the relative size of controller, cursor and target that significantly affected object transportation and orientation processes. There were significant interactions between controller size and cursor size as well as between cursor size and target size on the total task completion time, transportation time, orientation time and spatial errors. The same size of controller and cursor improved object manipulation speed, and the same size of cursor and target generally facilitated object manipulation accuracy, regardless of their absolute sizes. Implications of these findings for human-computer interaction design are discussed.”

Wang, Yanqing, MacKenzie, Christine L., Summers, Valerie A. and Booth, Kellogg S. (1998): The Structure of Object Transportation and Orientation in Human-Computer Interaction. In: Karat, Clare-Marie, Lund, Arnold, Coutaz, Joëlle and Karat, John (eds.) Proceedings of the ACM CHI 98 Human Factors in Computing Systems Conference April 18-23, 1998, Los Angeles, California. pp. 312-319. Available online

“An experiment was conducted to investigate the relationship between object transportation and object orientation by the human hand in the context of human-computer interaction (HCI). This work merges two streams of research: the structure of interactive manipulation in HCI and the natural hand prehension in human motor control. It was found that object transportation and object orientation have a parallel, interdependent structure which is generally persistent over different visual feedback conditions. The notion of concurrency and interdependence of multidimensional visuomotor control structure can provide a new framework for human-computer interface evaluation and design.”

Graham, Evan D. and MacKenzie, Christine L. (1996): Physical Versus Virtual Pointing. In: Tauber, Michael J., Bellotti, Victoria, Jeffries, Robin, Mackinlay, Jock D. and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 96 Human Factors in Computing Systems Conference April 14-18, 1996, Vancouver, Canada. pp. 292-299. Available online

“An experiment was conducted to investigate differences in performance between virtual pointing, where a 2-D computer image representing the hand and targets was superimposed on the workspace, and physical pointing with vision of the hand and targets painted on the work surface. A detailed examination of movement kinematics revealed no differences in the initial phase of the movement, but that the final phase of homing in on smaller targets was more difficult in the virtual condition. These differences are summarised by a two-part model of movement time which also captures the effects of scaling distances to, and sizes of targets. The implications of this model for design, analysis, and classification of pointing devices and positioning tasks are discussed.”
