“…However, 52% of participants disagreed that the scent lingered for too long. This is particularly important, as the issue of scent lingering has been shown to be a significant challenge in a olfactory-related media studies [29,38], yet was not found to be a negative issue in our empirical investigation. & Item 18 -I found the intensity of the smell too strong: Like audio quality or image resolution, scent intensity could affect the user experience.…”

People interact with computers using their senses. Currently, in a digital context, traditional digital media like videos and images used to convey information to users, and these media can be used as a source of information. However, relatively few studies have been conducted on olfactory media as a source of information in a digital context. In this paper, we report on a study that examined the possibility of using olfactory media as a source of information and whether its usage as informational cues enhances learning performance and user Quality of Experience (QoE). To this end, an olfactory-enhanced quiz (web-based) was developed about four countries. The quiz contained different types of questions employing four types of digital media in their contents: text, image, audio and olfactory media. Four scents were used that were considered to be related to the respective countries. Sixty-four participants were invited to our experiment to evaluate this application. Our results revealed that usage of olfactory media synchronised with traditional digital media had a significant impact on learner performance compared to the case when no olfactory media was employed. In respect of user QoE, it was found that olfactory media influenced users positively; moreover, they were passionate about engaging with enhanced olfactory applications in the future.

Unlike other sensory stimuli (specifically sight and sound), digital olfactory technology has yet to have wide-spread commercial success. Our proposed system will release up to 8 different liquid phase aromas (essential oils) using a thermal mechanism. The unit contains a speed controlled fan, temperature control of the heating element and a gas sensor to provide feedback to inform the release rate. It can be connected (via Bluetooth LE) to a tablet/computer to control the timing and intensity of the aroma. External measurements show that aromas can be detected within a few seconds of release and produce a broad range of intensities from low ppm to 10's of ppm.Index Terms-Aroma generator, digital olfaction, olfactory display. I. INTRODUCTIONHE field of olfaction has remained one of the most underdeveloped technological areas in our modern digital world. Though there have been significant advances in the way that information is presented to us as digital users -be it through visual or audio means, olfaction still appears to be a technology of the future. The reasons for this are complex and potentially associated with a mixture of factors, including the dominance of our other senses, poor training of the population in olfaction and a feeling that it is not an important sense. However, olfaction has the ability to enrich visuals and provide easier access to parts of our brain associated with, for example, long term memory [1].The potential applications for olfactory technology are significant and range from medical applications to virtual reality (VR). This could include helping with anxiety/stress or in the diagnosis of degenerative disorders such as Parkinson's disease. In tourism/museum environments, smells can be used to compliment sound and vision effects of historical sites to relive the past. Other applications include VR and multimedia to enhance gaming, television entertainment and beyond. There have even been attempts to create communication protocols based on gas phase chemical transmission instead of electrical [2]. Considering these applications, it is surprising that olfactory displays are not common throughout society and found in every home. There are a number of potential reasons for this, but one major gap is the lack of a simple, robust digital olfactory technology. These technologies should not be confused with most existing aroma approaches, such as air fresheners, perfumes (with paper smelling strips) or even candles, but are distinct in being able to provide a ra...
