“…On the usefulness of haptic feedback, which is implicit in the results of this UX study, it was found in [ 32 ] that device-driven haptic feedback may lead to increase consumer responses to certain consumer-directed communications, by improving consumer performance on related tasks and an increased sense of social presence. A more generic study on influence of haptic feedback on emotional arousal, sense of presence, and embodiment in virtual reality, can be found in [ 33 ], where the main conclusions also corroborate those obtained in this work, i.e., more engaging experience is obtained when haptic feedback is used. The above cited works have in common with this one the fact that actual users participated in different evaluation studies and the main conclusions are coherent among them all, i.e., the use of haptic feedback is beneficial from different perspectives.…”

Remote control devices are commonly used for interaction with multimedia equipment and applications (e.g., smart TVs, gaming, etc.). To improve conventional keypad-based technologies, haptic feedback and user input capabilities are being developed for enhancing the UX and providing advanced functionalities in remote control devices. Although the sensation provided by haptic feedback is similar to mechanical push buttons, the former offers much greater flexibility, due to the possibility of dynamically choosing different mechanical effects and associating different functions to each of them. However, selecting the best haptic feedback effects among the wide variety that is currently enabled by recent technologies, remains a challenge for design engineers aiming to optimise the UX. Rich interaction further requires text input capability, which greatly influences the UX. This work is a contribution towards UX evaluation of remote control devices with haptic feedback and text input. A user evaluation study of a wide variety of haptic feedback effects and text input methods is presented, considering different technologies and different number of actuators on a device. The user preferences, given by subjective evaluation scores, demonstrate that haptic feedback has undoubtedly a positive impact on the UX. Moreover, it is also shown that different levels of UX are obtained, according to the technological characteristics of the haptic actuators and how many of them are used on the device.

“…Additionally, developing experimental scenarios in which participants have to perform more complex locomotion tasks, e.g., side stepping or passing through narrow hallways, might be necessary to further understand the impact that the motion artifacts have on the sense of self-agency. Finally, in our future work, we would like to explore whether the sense of self-agency is affected when providing tactile feedback [52,53] to participant's body as well as how participants perceive self-agency when embodied to a virtual character with variations on his/her appearance [54,55].…”

The Effects of Motion Artifacts on Self-Avatar Agency

One way of achieving self-agency in virtual environments is by using a motion capture system and retargeting user’s motion to the virtual avatar. In this study, we investigated whether the self-agency is affected when motion artifacts appear on top of the baseline motion capture data assigned to the self-avatar. For this experiment, we implemented four artifacts: noise, latency, motion jump, and offset rotation of joints. The data provided directly from the motion capture system formed the baseline of the study. We developed three observation tasks to assess self-agency: self-observation, observation through a virtual mirror, and observation during locomotion. A questionnaire was adopted and used to capture the self-agency of participants. We analyzed the collected responses of participants to determine whether the motion artifacts significantly altered the participants’ sense of self-agency. The obtained results indicated that participants are not always sensitive to the motion artifacts assigned to the self-avatar, but the sense of self-agency is dependent on the observation task they were asked to perform. Implications for further research are discussed.

“…A similar work was presented recently in [2]. Regarding interaction with virtual characters, Krogmeier et al [26] designed an experiment where participants had to bump into a virtual character, with or without haptic rendering of contacts. This haptic rendering was performed using the "Tactsuit" 1 , equipped with 70 haptic points of contact.…”

“…Using an haptic device is generally expected to increase the user's immersion in the virtual world [26], as it adds a new sensorial feedback, even though it does not always lead to an increase of perceived realism [46]. For this reason, we measured Presence using the Slater-Usoh-Steed (SUS) questionnaire [48] (Table 5).…”

Fig. 1. Our objective is to understand whether and to what extent providing haptic rendering of collisions during navigation through a virtual crowd (right) makes users behave more realistically. Whenever a collision occurs (center), armbands worn on the arms locally vibrate to render this contact (left). We carried out an experiment with 23 participants, testing both subjective and objective metrics regarding the users' path planning, body motion, kinetic energy, presence, and embodiment.
