    Desktop vs. Headset: A Comparative Study of User Experience and Engagement for Flexibility Exercise in Virtual Reality

    Get PDF
    This study aimed to investigate the effectiveness of Virtual Reality (VR) technology for flexibility exercise and compare the physical outcomes, user experience, and engagement of VR desktops and VR headsets. The VR exercise application was designed using motion capture technology and exported to different VR devices. Each of the devices was used by 30 participants to perform a flexibility exercise in VR. Physical outcomes were measured using the sit-and-reach test, and user experience and engagement were evaluated using questionnaires and group discussions. The results showed that VR desktop participants had higher sit-and-reach scores. However, VR headset participants reported a more immersive experience (reality judgment) and motivation (value and usefulness). They also had higher engagement (focused attention and reward) levels than VR desktop participants. There were no significant differences between the two approaches in terms of enjoyment, effort, pressure, choice, correspondence, absorption, perceived usability, and aesthetic appeal. The study highlights the importance of considering physical outcomes, user experience, and engagement by comparing two different VR approaches for flexibility exercise. Further research is needed to explore the limitations and potential benefits of VR technology for physical activity. Doi: 10.28991/ESJ-2023-07-04-03 Full Text: PD

    VIRTUAL TOURISM: IDENTIFYING THE FACTORS THAT AFFECT A TOURIST\u27S EXPERIENCE AND BEHAVIORAL INTENTIONS IN A 3D VIRTUAL WORLD

    Given the increase in the use of technologies within the tourism industry, particularly the rising interest in virtual worlds such as Second Life, the purpose of this study is to identify the factors related to the 3D virtual tourism experience and behavioral intentions after visiting a virtual tourism destination. Two theories, the Technology Acceptance Model and Self-Determination Theory, were used to guide this study, both of which were found to be useful frameworks. Basecamp Maasai Mara in Second Life was selected as the research site, designed and developed through a collaborative effort at Clemson University. The results revealed that technological acceptance factors of tele-presence, perceived usefulness and perceived ease-of-use as described by the Technology Acceptance Model are significant factors related to both virtual tourist experiences and the behavioral intentions. In addition, the results obtained here indicate that psychological needs of autonomy, competence, and relatedness, as specified by the Self-Determination Theory, are significantly associated with virtual tourist experiences and behavioral intentions. The results of this study suggest that in designing virtual destinations, tourism practitioners need to consider consumers\u27 psychological needs of competence, autonomy and relatedness; for instance, the activities provided in Second Life Maasai Mara such as riding animated animals and listening to Maasai music were found to increase the virtual tourist\u27s autonomy. In addition, tourism marketers should consider the types of information provided as well as the media used to present the information, by including videos and music, for example, in order to enhance the perception of ease-of use and usefulness. As technology continues to evolve, more research is needed to understand the significance of the use of virtual worlds in the tourism industry as well as to generate a new paradigm shift in tourism literature

    Investigating Avatar Customization as a Motivational Design Strategy for Improving Engagement with Technology-Enabled Services for Health

    Technology-enabled services for physical and mental health are a promising approach to improve healthcare globally. Unfortunately, the largest barrier for effective technology-based treatment is participants' gradually fading engagement with effective novel training applications, such as exercise apps or online mental health training programs. Engaging users through design presents an elegant solution to the problem; however, research on technology-enabled services is primarily focused on the efficacy of novel interventions and not on improving adherence through engaging interaction design. As a result, motivational design strategies to improve engagement---both in the moment of use and over time---are underutilized. Drawing from game-design, I investigate avatar customization as a game-based motivational design strategy in four studies. In Study 1, I examine the effect of avatar customization on experience and behaviour in an infinite runner game. In Study 2, I induce different levels of motivation to research the effects of financial rewards on self-reported motivation and performance in a gamified training task over 11 days. In Study 3, I apply avatar customization to investigate the effects of attrition in an intervention context using a breathing exercise over three weeks. In Study 4, I investigate the immediate effects of avatar customization on the efficacy of an anxiety reducing attentional retraining task. My results show that avatar customization increases motivation over time and in the moment of use, suggesting that avatar customization is a viable strategy to address the engagement barrier that thwarts the efficacy of technology-enabled services for health

    Analyzing the Impact of Spatio-Temporal Sensor Resolution on Player Experience in Augmented Reality Games

    Along with automating everyday tasks of human life, smartphones have become one of the most popular devices to play video games on due to their interactivity. Smartphones are embedded with various sensors which enhance their ability to adopt new new interaction techniques for video games. These integrated sen- sors, such as motion sensors or location sensors, make the device able to adopt new interaction techniques that enhance usability. However, despite their mobility and embedded sensor capacity, smartphones are limited in processing power and display area compared to desktop computer consoles. When it comes to evaluat- ing Player Experience (PX), players might not have as compelling an experience because the rich graphics environments that a desktop computer can provide are absent on a smartphone. A plausible alternative in this regard can be substituting the virtual game world with a real world game board, perceived through the device camera by rendering the digital artifacts over the camera view. This technology is widely known as Augmented Reality (AR). Smartphone sensors (e.g. GPS, accelerometer, gyro-meter, compass) have enhanced the capability for deploying Augmented Reality technology. AR has been applied to a large number of smartphone games including shooters, casual games, or puzzles. Because AR play environments are viewed through the camera, rendering the digital artifacts consistently and accurately is crucial because the digital characters need to move with respect to sensed orientation, then the accelerometer and gyroscope need to provide su ciently accurate and precise readings to make the game playable. In particular, determining the pose of the camera in space is vital as the appropriate angle to view the rendered digital characters are determined by the pose of the camera. This defines how well the players will be able interact with the digital game characters. Depending in the Quality of Service (QoS) of these sensors, the Player Experience (PX) may vary as the rendering of digital characters are affected by noisy sensors causing a loss of registration. Confronting such problem while developing AR games is di cult in general as it requires creating wide variety of game types, narratives, input modalities as well as user-testing. Moreover, current AR games developers do not have any specific guidelines for developing AR games, and concrete guidelines outlining the tradeoffs between QoS and PX for different genres and interaction techniques are required. My dissertation provides a complete view (a taxonomy) of the spatio-temporal sensor resolution depen- dency of the existing AR games. Four user experiments have been conducted and one experiment is proposed to validate the taxonomy and demonstrate the differential impact of sensor noise on gameplay of different genres of AR games in different aspect of PX. This analysis is performed in the context of a novel instru- mentation technology, which allows the controlled manipulation of QoS on position and orientation sensors. The experimental outcome demonstrated how the QoS of input sensor noise impacts the PX differently while playing AR game of different genre and the key elements creating this differential impact are - the input modality, narrative and game mechanics. Later, concrete guidelines are derived to regulate the sensor QoS as complete set of instructions to develop different genres or AR games

    User Experience of Geocaching and Its Application to Tourism and Education

    Advances in technology have provided new ways of using entertainment and game technology to foster human interaction. Games and playing with games have always been an important part of people’s everyday lives. Traditionally, human-computer interaction (HCI) research was seen as a psychological cognitive science focused on human factors, with engineering sciences as the computer science part of it. Although cognitive science has made significant progress over the past decade, the influence of people’s emotions on design networks is increasingly important, especially when the primary goal is to challenge and entertain users (Norman 2002). Game developers have explored the key issues in game design and identified that the driving force in the success of games is user experience. User-centered design integrates knowledge of users’ activity practices, needs, and preferences into the design process. Geocaching is a location-based treasure hunt game created by a community of players. Players use GPS (Global Position System) technology to find “treasures” and create their own geocaches; the game can be developed when the players invent caches and used more imagination to creations the caches. This doctoral dissertation explores user experience of geocaching and its applications in tourism and education. Globally, based on the Geocaching.com webpage, geocaching has been played about 180 countries and there are more than 10 million registered geocachers worldwide (Geocaching.com, 25.11.2014). This dissertation develops and presents an interaction model called the GameFlow Experience model that can be used to support the design of treasure hunt applications in tourism and education contexts. The GameFlow Model presents and clarifies various experiences; it provides such experiences in a real-life context, offers desirable design targets to be utilized in service design, and offers a perspective to consider when evaluating the success of adventure game concepts. User-centered game designs have adapted to human factor research in mainstream computing science. For many years, the user-centered design approach has been the most important research field in software development. Research has been focusing on user-centered design in software development such as office programs, but the same ideas and theories that will reflect the needs of a user-centered research are now also being applied to game design (Charles et al. 2005.) For several years, we have seen a growing interest in user experience design. Digital games are experience providers, and game developers need tools to better understand the user experience related to products and services they have created. This thesis aims to present what the user experience is in geocaching and treasure hunt games and how it can be used to develop new concepts for the treasure hunt. Engineers, designers, and researchers should have a clear understanding of what user experience is, what its parts are, and most importantly, how we can influence user satisfaction. In addition, we need to understand how users interact with electronic products and people, and how different elements synergize their experiences. This doctoral dissertation represents pioneering work on the user experience of geocaching and treasure hunt games in the context of tourism and education. The research also provides a model for game developers who are planning treasure hunt concepts.Teknologinen kehitys on tarjonnut uusia tapoja hyödyntää viihdettä ja peliteknologiaa ihmisten välisessä vuorovaikutuksessa. Pelit ja niiden pelaaminen on ollut aina tärkeä osa ihmisten arkipäivää. Ihmisen ja tietokoneen välisen vuorovaikutuksen tutkimus, human-computer interaction research (HCI), on perinteisesti nähty kognitiivisena psykologiana, johon kuuluvat inhimilliset tekijät, sekä insinööritieteenä, johon sisältyy tietojenkäsittelytiede. Vaikka kognitiivinen tiede on kehittynyt viime vuosina valtavasti, suunnitteluverkostoihin vaikuttavat ihmisten tunteet ovat yhä tärkeämmässä osassa, erityisesti silloin kun tavoitteena on haastaa ja viihdyttää käyttäjiä. (Norman 2002.) Pelinkehittäjät ovat selvittäneet pelisuunnittelun kannalta olennaisia tekijöitä ja tunnistaneet, että pelien menestyksen salaisuus on käyttäjäkokemus. Käyttäjäkeskeisessä suunnittelussa käyttäjien toiminnan käytäntöjen, tarpeiden ja toiveiden tuntemus tuodaan mukaan suunnitteluprosessiin. Geokätköily on paikannukseen perustuva aarteenetsintäpeli, jonka pelaajat ovat luoneet yhdessä. Pelaajat käyttävät GPS-teknologiaa "aarteiden" etsimiseen ja lisäävät omia geokätkökohteita ja peli kehittyy jatkuvasti pelaajien keksiessä kätköjä, jotka vaativat yhä enemmän mielikuvitusta. Tässäväitöskirjassa tutkitaan geokätköilyn käyttäjäkokemusta ja sen sovelluksia koulutuksen- ja matkailunaloilla. Perustuen Geocaching.com websivustoon geokätköilyä pelataan noin 180 maassa, ja rekisteröityneitä käyttäjiä on yli kymmenen miljoonaa eri puolilla maailmaa (Geocaching.com, 25.11.2014). Tässä tutkielmassa esitellään vuorovaikutusmalli nimeltään GameFlow Experience -mallia, jota voidaan käyttää aarteenetsintäsovellusten suunnittelussa koulutuksen- ja matkailualojen konteksteissa. GameFlow Experience -malli esittelee ja selventää erilaisia kokemuksia - se esittelee ne todellisessa kontekstissa, tarjoaa erilaisia suunnittelutavoitteita palvelusuunnittelua varten sekä näkökulman, joka tulisi ottaa huomioon seikkailupelien menestystä arvioitaessa. Käyttäjäkeskeisessä pelisuunnittelussa on sovellettu inhimillisten tekijöiden tutkimusta valtavirran tietojenkäsittelytieteeseen. Useiden vuosien ajan, käyttäjäkeskeisen suunnittelun lähestymistavasta on tullut tärkein tutkimusala ohjelmistokehityksessä. Tutkimus on keskittynyt ohjelmistojen kehitykseen käyttäjäkeskeisessä suunnittelussa etenkin toimisto-ohjelmistoihin, mutta samoja ideoita ja teorioita, jotka heijastavat yhteiskunnan tarpeita käyttäjäkeskeisessä tutkimuksessa sovelletaan nyt myös pelisuunnitteluun. (Charles ja ym. 2005.) Kiinnostus käyttäjäkokemuksen suunnitteluun on kasvanut jo useiden vuosien ajan. Digitaaliset pelit tarjoavat kokemuksia, ja pelisuunnittelijat tarvitsevatkin työkaluja, joiden avulla voidaan entistä paremmin ymmärtää tuotteiden ja palvelujen luomia käyttäjäkokemuksia. Tutkimuksen tavoitteena on esitellä käyttäjäkokemusta ja miten sitä voidaan käyttää uusien aarteenmetsästyskonseptien kehittämiseen. Insinööreillä, suunnittelijoilla ja tutkijoilla tulisi olla selkeä käsitys siitä, mikä käyttäjäkokemus on, mitkä ovat sen osat ja mikä tärkeintä, miten voimme vaikuttaa käyttäjän tyytyväisyyteen. Lisäksi pitäisi ymmärtää, miten käyttäjät toimivat elektronisten tuotteiden kanssa sekä miten ihmiset toimivat vuorovaikutuksessa toistensa kanssa ja miten eri osat vaikuttavat yhdessä käyttäjien kokemuksiin. Väitöskirja on pioneerityö käyttäjäkokemuksesta geokätköilyssä ja aarteenetsintä peleissä matkailun ja opetuksen kontekstissa. Tutkimus antaa myös mallin pelin kehittäjille, jotka suunnittelevat aarteenetsintäkonsepteja.Siirretty Doriast

    UNDERSTANDING MOTIVATIONAL FACTORS OF PROBLEMATIC VIDEO GAMING IN THE USMC

    The goals of this thesis were to assess the prevalence of problematic video gaming within the United States Marine Corps (USMC), identify the motivational factors that lead Marines to engage in video gaming, assess the effects of video gaming on Marines’ lives, and investigate whether Marines use video gaming as a maladaptive coping mechanism. Survey data (n = 1,098 Marines) were collected from three USMC commands. In total, 847 Marines (91%) reported playing video games. Recreation and coping with stress were the most frequently reported motivational factors for playing video games. Most gamers (91%) reported playing video games while at home/off duty. In contrast, 20% of gamers reported playing video games while on duty/in port and 36% reported playing video games while underway/deployed. In our sample, five Marines (2%) were classified as disordered gamers. Disordered gamers reported using dysfunctional coping styles more frequently than the rest of gamers. Disordered gamers reported more severe symptoms of depression and anxiety, higher levels of loneliness, elevated daytime sleepiness, and more symptoms suggestive of heavy drinking. These findings led to three recommendations: a) educate Marines on the risks of problematic video gaming and the factors associated with gaming addiction, b) educate Marines on sleep hygiene practices, and c) implement strategies to mitigate the effects of problematic video gaming.Naval Postgraduate School, Monterey, CA 93940Lieutenant Junior Grade, United States NavyApproved for public release.
