abstract = {Virtual trackball techniques are widely used when 3D interaction is performed through interfaces with a reduced number of degrees of freedom such as mice and touchscreens. For decades, most implementations fix a vertical axis of rotation, which is a suitable choice when the vertical axis should indeed be fixed, according to some mental model of the user. We conducted an experiment involving the use of a mouse and a touch device to study usability in terms of performance, perceived usability and mental workload when selecting different fixed axes in accordance with the user’s mental model. The results we obtained indicate that the consistency between the axis fixed by the technique and the object’s intrinsic axis has a positive effect on usability. We believe that implementations that allow to select different fixed axis for each specific object should be considered when designing future reduced-DoF interaction interfaces.},

However, wearing an HMD while listening to real sound sources modifies the sound waves that reaches the listener's ears. In this work, we study the effect of HMDs on individualized HRTFs. We have collected acoustic HRTF measurements, with and without the HMD, from 24 human participants and a manikin head, over 612 directions (including different azimuth and elevation angles). An objective evaluation indicates that, although there are frequency-dependent directional regions where the distortion caused by the HMD is higher, other regions are less affected by the HMD. A MUSHRA test with 15 subjects compares individualized HRTFs and a generic HRTF, measured with and without HMD. The perceptual evaluation reveals a significant effect of the HMD on the measured individualized HRTF, but it also shows that this effect is significantly smaller than the difference between individualized HRTFs and a generic HRTF, as indicated by the objective evaluation. This implies that, although distorted by the presence of the HMD, some of the individualized HRTF characteristics might be preserved when the HMD is worn.},

Inertial sensors offer the potential for integration into wireless virtual reality systems that allow the users to walk freely through virtual environments. However, owing to drift errors, inertial sensors cannot accurately estimate head and body orientations in the long run, and when walking indoors, this error cannot be corrected by magnetometers, due to the magnetic field distortion created by ferromagnetic materials present in buildings. This paper proposes a technique, called EHBD (Equalization of Head and Body Directions), to address this problem using two head- and shoulder-located magnetometers. Due to their proximity, their distortions are assumed to be similar and the magnetometer measurements are used to detect when the user is looking straight forward. Then, the system corrects the discrepancies between the estimated directions of the head and the shoulder, which are provided by gyroscopes and consequently are affected by drift errors. An experiment is conducted to evaluate the performance of this technique in two tasks (navigation and navigation plus exploration) and using two different locomotion techniques: (1) gaze-directed mode (GD) in which the walking direction is forced to be the same as the head direction, and (2) decoupled direction mode (DD) in which the walking direction can be different from the viewing direction. The obtained results show that both locomotion modes show similar matching of the target path during the navigation task, while DD's path matches the target path more closely than GD in the navigation plus exploration task. These results validate the EHBD technique especially when allowing different walking and viewing directions in the navigation plus exploration tasks, as expected. While the proposed method does not reach the accuracy of optical tracking (ideal case), it is an acceptable and satisfactory solution for users and is much more compact, portable and economical.},

This study explores the influence of different sensory modalities on performance and the sense of presence experienced within a 3D environment. In: particular, we have evaluated visual, auditory and active haptic feedback for indicating selection of virtual objects. The effect of spatial alignment between proprioceptive and visual workspaces (co-location) has also been analysed. An experiment has been made to evaluate the influence of these factors in a controlled 3D environment based on a virtual version of the Simon game. The main conclusions obtained indicate that co-location must be considered in order to determine the sensory needs during interaction within a virtual environment. This study also provides further evidence that the haptic sensory modality influences presence to a higher extent, and that auditory cues can reduce selection times. Conclusions obtained provide initial guidelines that will help designers to set out better selection techniques for more complex environments, such as training simulators based on VR technology, by highlighting different optimal configurations of sensory feedback. © 2012 Springer Science+Business Media, LLC.},

This study explores the influence of different sensory modalities on performance and the sense of presence experienced within a 3D environment. In: particular, we have evaluated visual, auditory and active haptic feedback for indicating selection of virtual objects. The effect of spatial alignment between proprioceptive and visual workspaces (co-location) has also been analysed. An experiment has been made to evaluate the influence of these factors in a controlled 3D environment based on a virtual version of the Simon game. The main conclusions obtained indicate that co-location must be considered in order to determine the sensory needs during interaction within a virtual environment. This study also provides further evidence that the haptic sensory modality influences presence to a higher extent, and that auditory cues can reduce selection times. Conclusions obtained provide initial guidelines that will help designers to set out better selection techniques for more complex environments, such as training simulators based on VR technology, by highlighting different optimal configurations of sensory feedback. © 2012 Springer Science+Business Media, LLC.

In this paper, the evaluation of an interaction technique based on the metaphor of the natural hand in a virtual environment (VE) is presented. The aim of this study is the analysis of how the inclusion of passive haptic feedback affects the interaction within a VE. With this purpose an experiment with 18 subjects was conducted. The pilot design of this experiment and the implemented system used as a testbed are described. The evaluation of this interaction has been developed taking into account both, objective and subjective factors. A pilot experiment was conducted to study the relationship among haptic feedback, presence and task performance, and the obtained results are discussed. A new objective estimation of presence is also presented.

Those lacking experience were trained to properly act with the concrete clinical problem being simulated. During the experiment, the Galvanic Skin Response (GSR) of the subjects was recorded, and presence and stress questionnaires were completed by the subjects. The specialists in critical care with first hand experience report a high degree of presence in both environments tested, but subjects without such experience have a high degree of presence only in the stressful environment. This study found that results from stress and presence measurements show an evident correlation, making apparent a close relationship between both variables. Our results also show the importance of significant information when a high degree of presence or stress is needed in a VR training simulator.
