Publication Do low cost virtual reality devices support learning acquisition?: A comparative study of two different VR devices(Association for Computing Machinery, INC., 2019-06-25) Díaz, Paloma; Zarraonandia Ayo, Telmo Agustín; Sánchez de Francisco, Mónica; Aedo Cuevas, Ignacio; Onorati, Teresa; Ministerio de Economía y Competitividad (España)Virtual Reality (VR) can support engaging and effective learning and current VR devices commercially available are opening up opportunities and expectations in higher education. An open research question is determining whether the fidelity of the VR device (e.g. resolution, framerate, etc.) impacts learning. This work aims to address this question by conducting a study wherein the quality of the experience and the knowledge acquired using a high fidelity (and high priced) VR headset is compared against a lower fidelity (and lower priced) VR headset. The results of the study do not reveal significant difference in spatial and experiential learning. The user satisfaction and experience are also similar regardless of the headset used.Publication Altering body perception and emotion in physically inactive people through movement sonification(IEEE Xplore Digital Library, 2019-09-03) Ley Flores, Judith Guadalupe; Bevilacqua, Frédéric; Bianchi-Ber, Nadia; Tajadura Jiménez, Ana; Ministerio de Economía y Competitividad (España)Physical inactivity is an increasing problem. It has been linked to psychological and emotional barriers related to the perception of one's body, such as physical capabilities. It remains a challenge to design technologies to increase physical activity in inactive people. We propose the use of a sound interactive system where inputs from movement sensors integrated in shoes are transformed into sounds that evoke body sensations at a metaphorical level. Our user study investigates the effects of various gesture-sound mappings on the perception of one's body and its movement qualities (e.g. being flexible or agile), the related emotional state and movement patterns, when people performed two exercises, walking and thigh stretch. The results confirm the effect of the "metaphor" conditions vs. the control conditions in feelings of body weight; feeling less tired and more in control; or being more comfortable, motivated, and happier. These changes linked to changes in affective state and body movement. We discuss the results in terms of how acting upon body perception and affective states through sensory feedback may in turn enhance physical activity, and the opportunities opened by our findings for the design of wearable technologies and interventions in inactive populations.
