“…Howlett et al [14] analyzed differences in task performance and eye movements on the same object sorting task performed in a real environment and a VR reproduction of the same environment using back-projection and a haptic input device. They found that their VR reproduction of reality -while quite close to the original -had some effects on the participants.…”

Virtual Reality (VR) Head-Mounted Displays (HMDs) are on the verge of becoming commodity hardware available to the average user and feasible to use as a tool for 3D work. Some HMDs include front-facing cameras, enabling Augmented Reality (AR) functionality. Apart from avoiding collisions with the environment, interaction with virtual objects may also be affected by seeing the real environment. However, whether these effects are positive or negative has not yet been studied extensively. For most tasks it is unknown whether AR has any advantage over VR. In this work we present the results of a user study in which we compared user performance measured in task completion time on a 9 degrees of freedom object selection and transformation task performed either in AR or VR, both with a 3D input device and a mouse. Our results show faster task completion time in AR over VR. When using a 3D input device, a purely VR environment increased task completion time by 22.5 percent on average compared to AR ( ). Surprisingly, a similar effect occurred when using a mouse: users were about 17.3 percent slower in VR than in AR ( ). Mouse and 3D input device produced similar task completion times in each condition (AR or VR) respectively. We further found no differences in reported comfort.

“…The results from these studies indicate that there are correlations and many similarities between the two. However, it is not an easy task to design an empirical study to investigate this relationship (Howlett et al, 2005). In the Howlett study the respective times taken to complete tasks in the real and virtual worlds were compared in order to establish how well the virtual experience mimicked the real-world scenario.…”

It is the experience that counts, there and then. When a person talks about the experience, he or she can also reflect on and interpret the experience. In this chapter we use findings from empirical studies and surveys to write about the subjective reality of digital travel. We discussed the theoretical foundation for why we can have the feeling of being there (and what we referred to as the Spinozan model of perception) in Chapters 2 and 3. The first studies we report are on factors affecting the sense of place experience, and telepresence, using video games to create a sightseeing environment for participants. The second study is a survey of citizens on the topic of vacation planning, digital travel applications before, during and after visiting a tourist destination.

Integrating physical and virtual environments has been shown to improve usability of Virtual Reality (VR) applications. Objects within these mixed realities (MR [1]) can be hybrid physical/virtual objects that are physically manipulatable and have flexible shape and texture.We compare usability of hybrid objects for basic manipulation tasks (rotation, positioning) to physical and virtual objects. The results suggest that hybrid objects are manipulated faster than virtual objects, but not more accurately. Physical objects outperform both hybrid and virtual objects in terms of speed and accuracy. On the other hand, users felt most stimulated by the virtual objects, followed by the hybrid and physical objects.The study shows that hybrid objects "work" in virtual environments, but further investigations regarding the factors influencing their usability are needed.
