Virtual reality is rapidly expanding its capabilities and accessibility to consumers. The application of virtual reality in training for precision tasks has been limited to specialized equipment such as a haptic glove or a haptic stylus, but not studied for handheld controllers in consumer-grade systems such as the HTC Vive. A straight-line precision steadiness task was adopted in virtual reality to emulate basic linear movements in industrial operations and disability rehabilitation. This study collected the total time and the error time for the straight-line task in both virtual reality and a physical control experiment for 48 participants. The task was performed at four different gap widths, 4mm, 5mm, 6mm, and 7mm, to see the effects of virtual reality at different levels of precision. Average error ratios were then calculated and analyzed for strong associations to various factors. The results indicated that a combination of Environment x Gap Width factors significantly affected average error ratios, with a p-value of 0.000. This human factors study also collected participants’ ratings of user experience dimensions, such as difficulty, comfort, strain, reliability, and effectiveness, for both physical and virtual environments in a questionnaire. The results indicate that the ratings for difficulty, reliability, and effectiveness were significantly different, with virtual reality rating consistently rating worse than the physical environment. An analysis of questionnaire responses indicates a significant association of overall environment preference (physical or virtual) with performance data, with a p-value of 0.027. In general, virtual reality yielded higher error among participants. As the difficulty of the task increased, the performance in virtual reality degraded significantly. Virtual reality has great potential for a variety of precision applications, but the technology in consumer-grade hardware must improve significantly to enable these applications. Virtual reality is difficult to implement without previous experience or specialized knowledge in programming, which makes the technology currently inaccessible for many people. Future work is needed to investigate a larger variety of precision tasks and movements to expand the body of knowledge of virtual reality applications for training purposes.

Is it a dream came true for you to experience a Virtual Reality (VR) and be able to touch virtual objects and manipulate them with your bare hands? The recent growth of the Virtual Reality market resulted in an intensification of the development of the haptics gloves technology. The newly haptics gloves, Bebop gloves launched and commercialized recently which will use for this study. Earlier research has explored a range of haptics effects mainly on VR surgery or gaming. Yet, VR industrial training has gradually received attention in recent years. Creating multiple scenarios in the virtual scene is not only cost-effective but also increases safety and reduces training time. However, not many research studies have explored using haptic gloves in the VR industrial training environment. This study tries to complement earlier research by investigating usability and user performance using bebop vibration gloves in VR industrial training. The purposes were to provide a usability review of bebop gloves and explored the effect of haptics in VR industrial training. Three different haptics settings (Non-haptics, Partial haptics, and Full-haptics) were being set up. Eighteen users were then recruited to try randomly two haptics settings. Each user had to complete a five steps VR industrial training task while “thinking aloud”, followed by questionnaires and interviews after the task. The error and time recorded for each training step. These results confirmed several conclusions drawn in earlier research about how the haptics affect user performance in the VR environment, as well as how the behavior changes when using the haptics gloves in a VR environment. Last but not least the results also pointed to the importance of vibration haptics benefits in small-scale actions and provide the user with an interpersonal confirmation. / Är det en dröm som förverkligades för dig att uppleva en virtuell verklighet (VR) och kunna röra virtuella objekt och manipulera dem med bara händer? Den senaste tillväxten av marknaden för Virtual Reality resulterade i en intensifiering av utvecklingen av haptikhandskar-tekniken. De nyligen haptiska handskarna, Bebophandskar lanserade och kommersialiserades nyligen som kommer att användas för denna studie. Tidigare forskning har undersökt en rad haptiska effekter främst på VR-kirurgi eller spel. Ändå har VR-industriell utbildning gradvis fått uppmärksamhet under de senaste åren. Att skapa flera scenarier i den virtuella scenen är inte bara kostnadseffektivt utan ökar också säkerheten och minskar tiden. Men inte många forskningsstudier har undersökt användning av haptiska handskar i VR: s industriella utbildningsmiljö. Denna studie försöker komplettera tidigare forskning genom att undersöka användbarhet och användarprestanda med hjälp av bebop-vibrationshandskar i VR-industriutbildning. Syftena var att tillhandahålla en användbarhetsgranskning av bebop-handskar och utforska effekten av haptik i VR-industriutbildningen. Tre olika haptikinställningar (Non-haptics, Partial haptics och Full-haptics) inställdes. Atten användare rekryterades sedan för att testa slumpmässigt två haptikinställningar. Varje användare måste genomföra en femstegs VR-industriell träningsuppgift medan han ”tänker högt”, följt av frågeformulär och intervjuer efter uppgiften. Felet och tiden som registrerats för varje träningssteg. Dessa resultat bekräftade flera slutsatser som dragits i tidigare forskning om hur haptiken påverkar användarnas prestanda i VR-miljön, liksom hur beteendet förändras när man använder haptikhandskarna i en VR-miljö. Sist men inte minst pekade resultaten också på vikten av fördelar med vibrationshaptik i småskaliga åtgärder och ger användaren en interpersonell bekräftelse.

Text in English / Since its inception in 1833 the Evangelical Presbyterian Church in South Africa has been a missionary church and has always had its own missionary work. It started to organise the Christianization, Evangelization and Westernization endeavours to take place inside the territories of South Africa. The Evangelical Presbyterian Church Missionaries founded, financed, maintained, controlled and administered their educational endeavours without any moral or financial support from the Government. The main purpose of the Evangelical Presbyterian Church Missionaries in founding and supporting schools has been to use education as an auxiliary to the evangelization of the indigenous people of South Africa. Elementary schools served as instruments of direct evangelization rather than secular education. Pupils were taught the 3 R's, namely, reading, writing and arithmetic. Education was a useful tool that enabled the converts to read the Bible and other religious material on their own and preferably in their own language. Converts who demonstrated the ability to read, write and do simple arithmetic were trained to become missionaries' helpers. As these earliest converts became proficient and competent, they were posted out into the interior with the instructions to start new church centres and schools. Although the teaching which took place inside these schools was not of high quality, it was definitely better than nothing. The Evangelical Presbyterian Church Missionaries together with missionaries of other denominations provided virtually all the education which was available for the Blacks in South Africa. Through missionary endeavours the South African Government have realized that Western education and civilization has been important forces which helped the indigenous people to advance individually and collectively in the social, political and economic fields. Western technology and culture successfully won the indigenous people of South Africa to Western civilization. The acceptance of Christianity and the introduction of the White man's rule in the interior of South Africa effectively stopped the inter-tribal wars. The missionaries have made a noteworthy contribution to the education of the indigenous people of South Africa. They empowered the Blacks to play a worthy part side by side with members of other races (Whites, Coloureds and Indians) in the development of the country they shared. / Educational Studies / D.Ed.
