“…H1: Due to different spatial abilities of men and women (Luursema et al 2008;Waller 2000), it is expected that gender will have an influence on the task completion time for both selection and positioning tasks, as well as on the people's choice for available interaction strategies, where strategies are observed behaviors that certain participants performed to increase their overall performance. H2: Age is expected to play a role in both time and accuracy.…”

“…Related literature reports on notable individual differences in spatial behavior attributable to computer experience (Wingrave et al 2005), gender (Larson et al 1999;Waller 2000) and spatial abilities (Luursema et al 2008;Rizzo et al 2000). Relevant research includes comparing spatial information transfer of virtual environments to the real world (Waller et al 2001) and real world studies such as selecting objects with a laser pointer (Myers et al 2002).…”

User-centered design is often performed without regard to individual user differences. In this paper, we report results of an empirical study aimed to evaluate whether computer experience and demographic user characteristics would have an effect on the way people interact with the visualized medical data in a 3D virtual environment using 2D and 3D input devices. We analyzed the interaction through performance data, questionnaires and observations. The results suggest that differences in gender, age and game experience have an effect on people's behavior and task performance, as well as on subjective user preferences.

Improved depth perception with three-dimensional auxiliary display and computer generated three-dimensional panoramic overviews in robot-assisted laparoscopy

Abstract.In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by connecting live 3-D monitors to all three available Da Vinci generations, probed user experience after two years by questionnaire, and compared time measurements of a predefined complex interaction task performed with a 3-D monitor versus two-dimensional. Additionally, we investigated whether the complex mental task of reconstructing a 3-D overview from an endoscopic video can be performed by a computer and shared among users. During the study, 925 robot-assisted laparoscopic procedures were performed in three hospitals, including prostatectomies, cystectomies, and nephrectomies. Thirty-one users participated in our questionnaire. Eighty-four percent preferred 3-D monitors and 100% reported spatial-perception improvement. All participating urologists indicated quicker performance of tasks requiring delicate collaboration (e.g., clip placement) when assistants used 3-D monitors. Eighteen users participated in a timing experiment during a delicate cooperation task in vitro. Teamwork was significantly (40%) faster with the 3-D monitor. Computer-generated 3-D reconstructions from recordings offered very wide interactive panoramas with educational value, although the present embodiment is vulnerable to movement artifacts.

“…Mourant and Parsi (2002) found that people who trained a pick-and-place task in a stereo environment performed better on one aspect of a real world posttest than participants who had trained in a monoscopic environment. An experiment of Luursema et al (2008) found that computer-implemented stereopsis provided a small positive effect on learning of anatomy in the medical field. The authors considered that more research was needed before advising to implement stereopsis-enabling hardware in medical settings.…”
