An Indoor Navigation System Using a Sensor Fusion Scheme on Android Platform

With the development of wireless communication networks, smart phones have become a necessity for people’s daily lives, and they meet not only the needs of basic functions for users such as sending a message or making a phone call, but also the users’ demands for entertainment, surfing the Internet and socializing. Navigation functions have been commonly utilized, however the navigation function is often based on GPS (Global Positioning System) in outdoor environments, whereas a number of applications need to navigate indoors. This paper presents a system to achieve high accurate indoor navigation based on Android platform. To do this, we design a sensor fusion scheme for our system. We divide the system into three main modules: distance measurement module, orientation detection module and position update module. We use an efficient way to estimate the stride length and use step sensor to count steps in distance measurement module. For orientation detection module, in order to get the optimal result of orientation, we then introduce Kalman filter to de-noise the data collected from different sensors. In the last module, we combine the data from the previous modules and calculate the current location. Results of experiments show that our system works well and has high accuracy in indoor situations

Interpassivity and the joy of delegated play in idle games

This paper examines the youngest video games genre, the so called idle (incremental) game, also referred to as the passive, self-playing or clicker game, which seems to challenge the current understanding of digital games as systems, based on a human-machine interaction where it is the human who actively engages with the system through meaningful choices. Idle games, on the other hand, tend to play themselves, making the player’s participation optional or, in some cases, entirely redundant. Interactivity and agency – qualities extensively theorised with reference to digital games – are questioned in the context of idling. In this paper the author will investigate the self-contradictory genre through the lens of interpassivity, a concept developed by Robert Pfaller and Slavoj Žižek to describe the aesthetics of delegated enjoyment. This contribution aims at introducing interpassivity to a wider Game Studies community, and offers an alternative perspective to reflect upon digital games in general and self-playing games in particular

Hack the room:an augmented reality game for non-experts to learn ethical hacking

Abstract. The shortage of cybersecurity skills caused by a widespread talent drought is having a signifcant economic impact on organizations globally. Several initiatives have been implemented to address this defcit, providing new educational pathways for novice and advanced students. Recently, ethical hacking gamifcation platforms and Capture the Flag (CTF) online games have risen in popularity, offering fun and engaging content that motivate beginners to acquire offensive and defensive cybersecurity skills. However, the use of augmented reality (AR) applications for cybersecurity skill development remains mostly unexplored. Against this backdrop, the overall aim of the thesis is to examine whether CTF games in AR can improve learning outcomes in information security and enhance security situational awareness. Specifcally, we explore how AR gamifcation impacts training and overall experience in the context of ethical hacking tasks. To achieve this, we have created Hack the Room, which is an ethical hacking game developed in Unity, where players use Linux terminals to solve CTF-style tasks. The game can be used for learning key cybersecurity concepts vital for organizations, and target users who have no previous cybersecurity experience, and need to be retrained for future-proofng organizations. In the game, the player has to use simple simple Linux terminal commands like listing fles in directories and reading fles stored in virtual machines hosted in the cloud (CSC Pouta) to reach the predetermined tasks. Each playthrough lasts 20 minutes and features three tasks. The game can be modifed or made more diffcult by changing the tasks in the virtual machine. The main goal of the game is to complete all of the tasks in the game. Our gamifcation concept was evaluated in a feld experiment that included six participants divided into two groups, an expert group (N=3) and a non-expert group (N=3). The expert group responded to a questionnaire that assessed their situational awareness during the game, while the non-expert group responded to a questionnaire that evaluated learning outcomes. The participants reported positive learning outcomes and high situational awareness after playing the game.Hack the room : lisätyn todellisuuden peli eettisen hakkeroinnin oppimiseen. Tiivistelmä. Pula tietoturvaosaamisesta vaikuttaa taloudellisesti organisaatioihin maailmanlaajuisesti. Tämän puutteen korjaamiseksi on tehty useita aloitteita, joissa tarjotaan oppipolkuja aloitteleville sekä edistyneemmille oppillaille. Eettisen hakkeroinnin pelillistämisalustat sekä Capture the Flag- (CTF) (suom. lipunryöstö) verkkopelit ovat lisänneet suosiotaan viime vuosina ja ne tarjoavat hyvän mahdollisuuden vasta-alkajille opetella tietoturvahyökkäämistä ja -puolustamista. Lisätyn todellisuuden hyödyntämistä tietoturvakoulutuksessa ei ole kuitenkaan tutkittu laajalti. Tässä kandidaatin tutkinnossa käsitellään lisätyn todellisuuden hyödyntämistä CTF-peleissä sekä sitä, miten lisätty todellisuus vaikuttaa tietoturvallisuuden ja turvallisuuden tilannetietoisuuden oppimiseen. Käsittelemme erityisesti, miten lisätyn todellisuuden pelillistäminen vaikuttaa harjoitteluun sekä yleiseen kokemukseen eettisissä hakkerointitehtävissä. Tämän mahdollistamiseksi loimme Hack the Roomin, joka on Unityssä kehitetty kyberturvallisuuspeli, jossa pelaajat käyttävät Linux-terminaaleja läpäistäkseen lipunryöstötyyppisiä tehtäviä. Sitä voidaan käyttää työkaluna henkilöiden tietoturvaan tutustuttamiseen, kouluttamiseen ja uudelleen opettamiseen. Pelin tehtävät koostuivat yksinkertaisista tehtävistä, joissa käytettiin Linuxkomentoja, kuten tiedostojen listaamista ja -lukemista. Jokainen pelikerta on 20 minuutin pituinen ja sisältää kolme tehtävää. Peliä voi muokata tarpeiden mukaan, esimerkiksi nostaa vaikeustasoa muuttamalla pelin virtuaalikonetta. Pelin käyttämä virtuaalikone sijaitsee CSC Pouta-palvelimella. Kehittämämme pelillistämiskonsepti evaluoitiin kenttäkokeella. Kokeessa oli 6 osallistujaa, jotka jaettiin kahteen ryhmään. Ryhmät koostuivat asiantuntijoista ja henkilöistä, joilla ei ollut aiempaa kokemusta eettisestä hakkeroinnista. Asiantuntijoiden ryhmä vastasi kyselyyn, joka mittasi heidän tilannetietoisuuttaan ja toinen ryhmä kyselyyn, joka mittasi heidän oppimistaan pelissä. Kenttäkoe osoitti sekä positiivisia oppimistuloksia, että korkeaa tilannetietoisuutta pelissä

New Spectacles for Juliette: Values and Ethics for Creative Business

This is the third book in an on-going series published by Nottingham Creative Network which was established in 2006 as a re-incarnation of Creative Collaborations which was established in 2003. Both incarnations offer(ed) professional and business development advice, support, training and networking opportunities made relevant for the specific and sometimes non-standard ways that creative businesses operate and exchange. This series of books occupies a cross-over space between broad conceptual debates, creativity itself, ideas for creative business and concrete advice for professional development. The first in this series is entitled Fish, Horses and Other Animals; Professional and Business Development for the Creative Ecology and tries to offer some ideas about understanding and engaging with informal creative business networks. The second, Soul Food, and Music: Research and Innovation for Creative Business explores ways to consolidate research for creative business and use it for thinking about innovation. As you will see, this third book continues the theme of professional and business development for the specifics of creative business by introducing questions of values and ethics into our broader on-going discussion

Sex Education: Ancient Israel and Igbo Traditional Practices

Every human (male and female) is a sexual being. Exploring and experiencing one’s sexuality is part of being human. Unfortunately, human’s curiosity and interest concerning sexuality are not always guided and nurtured in a wholesome way because sex is viewed as sacred and talking about it constitutes a taboo. Hence, many parents are at ease to teach their children about virtually every other thing in life, but they usually do not, however, teach about sexuality with similar ease. As a result, many grow into adulthood with partial and  distorted views of human sexuality. The aim of the study was to discover the teachings of Proverbs 7:24-27 on sex education along traditional practices in tone with sex education in Igbo culture and determine the place of proper sex education for better dealing and understanding of human sexuality. The study adopted African  inculturation hermeneutics which makes African social cultural context the subject of interpretation. The study revealed that sex education was integral to the training of the young adults in ancient Israel Igbo cultures. However, the study observed some areas of strength and weaknesses of sexuality training in Igbo traditional practices. Thus, the research upheld that the instructions on human sexuality preserved in the book of Proverbs are very relevant in strengthening the contemporary Igbo culture and her traditional practices in the training of young adults in the areas of chastity. Therefore, the paper called for proper sex education in the Igbo society to instill sexual purity among youths of contemporary Igbo society
