Multisensory games-based learning - lessons learnt from olfactory enhancement of a digital board game

Abstract

Serious games are becoming an alternative educational method in a variety of fields because of their potential to improve the quality of learning experiences and to facilitate knowledge acquisition and content understanding. Moreover, entertainment-driven learners are more easily motivated to benefit from the learning process through meaningful activities defined in a game context. Interfacing educational computer games with multisensorial interfaces allows for a seamless integration between virtual and physical environments. Multisensorial cues can improve memory and attention and increase the cognitive and sensory-motor performance. Despite of the increasing knowledge in sensory processes, multisensory experiences and interactions in computer based instruction remain insufficiently explored and understood. In this paper, we present a multisensory educational gameFragrance Channel -and we investigate how enabling olfaction can contribute to users' learning performance, engagement and quality of experience. We compare results obtained after experiencing Fragrance Channel in the presence and absence of olfactory feedback on both a mobile and a PC. A knowledge test administered before and immediately after showed that our proposed educational game led to an improvement of performance in all the explored conditions. Subjective measurements carried out after the olfactory experience showed that students enjoyed the scenario and appreciated it as being relevant.

Less is (Just as Good as) More - an Investigation of Odor Intensity and Hedonic Valence in Mulsemedia QoE using Heart Rate and Eye Tracking

“…One of the few research endeavors which examined the impact of odor valences on QoE is that of Kroupi et al [29]. In this study, authors have analyzed electroencephalogram (EEG) data of users experiencing hedonically different odors, whilst earlier work [46] [51] also explored the use of odors to enhance emotions in a game-playing setting, whilst highlighting the potential of odors for an increased QoE in games-based learning [11]. Moreover, Murray et al [33] explored the perception of timing depending on the scent type (pleasant/unpleasant) presented to the participants.…”

Ethical Consumption Communities Across Physical and Digital Spaces: An Exploration of Their Complementary and Synergistic Affordances

“…Indeed, first attempts to design digital spaces that afford more multisensorial experiences are slowly becoming a reality (e.g. Covaci et al 2018). Altogether then, our study points to the increasingly intricate spatial nature of contemporary ethical consumption communities, and its capacity to further (but also hinder) their efforts to address a variety of social and environmental injustices.…”

Communicating cosmology with multisensory metaphorical experiences

“…This "embodiment of ideas" opens the door to a deeper emotional and intuitive response [Hamza-Lup and Stanescu, 2010;Gibbs, 2014;Obrist, Tuch and Hornbaek, 2014], rather than a purely intellectual one. Multi-channel sensory stimulation, including olfactory effects, have been reported to improve engagement, enjoyment and knowledge acquisition [Covaci et al, 2018;Olofsson et al, 2017;Brulé and Bailly, 2018].…”
