Impact of Mediation devices on the Museum Visit Experience and on Visitors' Behavioural Intentions
2012
This study draws on the experiential approach and has two main goals: to explore the different dimensions of the museum experience regardless of whether it is mediated by mediation devices (e.g., audio guides, interactive terminals, SmartPhones, tablets, augmented reality), and to identify the impact of such devices on visitors' behavioural intentions. The authors conduct a qualitative and exploratory investigation to address the following questions: Does the development of such devices affect both experience dimensions and the audience's behavioural intentions? Which components of a museum visit are concerned?
IncentMe: Effective Mechanism Design to Stimulate Crowdsensing Participants with Uncertain Mobility
2018
Mobile crowdsensing harnesses the sensing power of modern smartphones to collect and analyze data beyond the scale of what was previously possible with traditional sensor networks. Given the participatory nature of mobile crowdsensing, it is imperative to incentivize mobile users to provide sensing services in a timely and reliable manner. Most importantly, given sensed information is often valid for a limited period of time, the capability of smartphone users to execute sensing tasks largely depends on their mobility pattern, which is often uncertain. For this reason, in this paper, we propose IncentMe, a framework that solves this core issue by leveraging game-theoretical reverse auction …
Determining the efficiency of optical sources using a smartphone's ambient light sensor
2017
This work reports the use of a smartphone’s ambient light sensor as a valuable tool to study and characterize the efficiency of an optical source. Here, we have measured both luminous efficacy and efficiency of several optical sources (incandescent bulb and halogen lamp) as a function of the electric power consumed and the distance to the optical detector. The illuminance of LEDs as a function of the distance to the optical detector is characterized for different wavelength emissions. Analysis of the results confirms an inverse-square law of the illuminance with the detector–source distance and shows good agreement with values obtained by classical experiments. This experience will trigger …
Identification of the cannabinoid receptor type 1 in serotonergic cells of raphe nuclei in mice.
2007
The endocannabinoid system (ECS) possesses neuromodulatory functions by influencing the release of various neurotransmitters, including GABA, noradrenaline, dopamine, glutamate and acetylcholine. Even though there are studies indicating similar interactions between the ECS and the serotonergic system, there are no results showing clear evidence for type 1 cannabinoid receptor (CB1) location on serotonergic neurons. In this study, we show by in situ hybridization that a low but significant fraction of serotonergic neurons in the raphe nuclei of mice contains CB1 mRNA as illustrated by the coexpression with the serotonergic marker gene tryptophane hydroxylase 2, the rate limiting enzyme for t…
Implementing a Digital Wellness Application into Use : Challenges and Solutions Among Aged People
2020
The ageing population is a growing priority area for policy makers and healthcare providers worldwide. Life expectancy is improving, but at the same time, insufficient physical activity threatens older age. Thus, an important question arises: how to improve the probability of people living a healthy and active life in older age. One potential solution to support physical activity and healthy aging is digital wellness technologies. However, digital wellness technologies are still typically designed for younger populations, yet a growing need and potential also among aged people is prevalent. Aged people are a user group with distinct needs and challenges. The main purpose of this study was t…
Experience from Indoor Fire Search and Rescue Game Design for Technology Testing
2018
No matter how good the fire evacuation plan for a building is, there is a risk of immovable victims being left behind due to smoke obscuration, inhalation of poisonous gasses, or other reasons. Firefighters usually perform the search and rescue for casualties in responding to fire hazards, besides the firefighting. Among of the challenges in the search and rescue operation is how to locate victims, and to keep monitoring the fire development so that it will not accidentally harm the fire personnel. This paper presents a game designed to test a smartphone app’s feature that supports concurrent tracking of indoor victims and fire spread. 22 volunteers were assigned roles either as rescuers or…
Are smartphone applications (App) useful to improve hearing?
2020
Le App per smartphone possono essere utili per migliorare l’udito?L’obiettivo dello studio è quello valutare l’efficacia di un’App per smartphone creata con lo scopo di migliorare le performance uditive sia in soggetti normoudenti che in pazienti affetti da ipoacusia da lieve a severa. Si tratta di uno studio analitico multicentrico, eseguito tra giugno e dicembre 2017, che ha analizzato un campione di 68 pazienti di cui 55 ipoacusici e 13 normoudenti; a tutti i pazienti sono stati somministrati test audiologici specifici sia durante l’utilizzo della suddetta App che in assenza di ausili uditivi. Il protocollo di valutazione audiologica prevedeva l’esecuzione di un’audiometria tonale limina…
Naive Bayes classier-based fire detection using smartphone sensors
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 For many years, smoke detectors have been used as the most crucial _re detection sensors.Although smoke detectors do their job very well, they are not perfect and may causefalse or late alarms. This is because they only rely on one of the _re signs which is smoke.Fire has many other signs as well such as heat and light. It also a_ects its environmentalparameters such as temperature and humidity. But typically, buildings are not equippedwith sensors capable of sensing these changes. Recently, a few smartphone manufacturershave added temperature, humidity, and barometer sensors to their products which c…
Evaluation of Erythema Severity in Dermatoscopic Images of Canine Skin: Erythema Index Assessment and Image Sampling Reliability.
2021
The regular monitoring of erythema, one of the most important skin lesions in atopic (allergic) dogs, is essential for successful anti-allergic therapy. The smartphone-based dermatoscopy enables a convenient way to acquire quality images of erythematous skin. However, the image sampling to evaluate erythema severity is still done manually, introducing result variability. In this study, we investigated the correlation between the most popular erythema indices (EIs) and dermatologists’ erythema perception, and we measured intra- and inter-rater variability of the currently-used manual image-sampling methods (ISMs). We showed that the EIBRG, based on all three RGB (red, green, and blue) channe…
iViaggio: the app for safe traveling.
2019
he number of people travelling internationally increases year after year, mainly due to the more and more affordable cost of travelling and to the evergreater ease of transportation. Nowadays, any destination can be reached within 24 hours by plane, and the improvement of economic conditions facilitates both business and leisure travelling, as a matter of fact, according to data from the World Tourism Organization, the number of international trips is expected to increase by 3% to 4% per year.1 However, international travelling poses various health risks depending on travelers’ health conditions and the type of trip undertaken. Indeed, travelers may experience sudden changes in altitude, hu…
