“…Markers or computer vision algorithms are used to detect the object's position and to match the animated 3D models. Such systems are usually found as mobile phone applications or stationary cameras with a computer screen [21]. Deployment is also problematic in some cases because mobile devices will not work long enough due to low battery life, low processing power and poor cooling designs -computer vision algorithms are very demanding on computing power (this can be compensated by the use of a desktop computer for calculations, but at the cost of losing mobility, or solved hybridlike using a cloud system).…”

A Smart Factory in a Smart City: Virtual and Augmented Reality in a Smart Assembly Line

Increasingly, the smart city space is requiring a reconceptualization of forms and factors of production, including factories and their place in the smart city space. Factories have always been a part of the city and many people spend a significant part of their lives there. Cities and factories share the same physical space and draw from the same resources, such as the energy grid, communication networks, public utilities, social connections, etc. Factories and cities should share the same IoT network in order to maximize their synergy level. In this view, as ICT-enhanced solutions are being implemented and so the concept of the smart city becomes a reality, it is mandatory that the connection between the smart city and the smart factory is examined. This paper represents the first step in this direction. We are presenting a new smart way to lighten the workload for employees (especially those involved in assembly, setup and maintenance) and increase factory efficiency. We have developed a brand-new smart solution for designing and presenting work instructions. The solution can be easily adapted to use in other fields like healthcare or smart-homes. This paper presents a comparison of different types of virtual/augmented and conventional assembly instructions. Today, we face the challenge of a lack of skilled employees and a high rate of employee turnover. Both result in huge time and production losses, because new employees have to be taught simple assembly tasks over and over again. In addition, as companies begin hiring many more foreign workers who do not understand the local language, the challenge of teaching becomes even more acute. Despite this, in modern production systems we can still find ineffective and complicated books and manuals with assembly, service and measurement instructions. We have prepared several variants for non-trivial multistep assembly instructions: traditional ''paper'' instructions, video instructions, virtual instructions on screen (with/without in-situ projection and with/without a special controller). We have developed our own software system for working with and developing virtual assembly instructions. In this case the in-situ augmentation is a projection on to different parts of the workplace. 60 subjects were tested over two years in order to gather the learning curve for each of 5 types of instructions using virtual and augmented reality. We have proven that using any type other than ''paper'' will shorten the learning time by approximately half. Practitioner summary: We have prepared and tested variants for non-trivial multi-step assembly instructions. 60 subjects were tested over two years in order to gather the learning curve for all 5 types of instructions-traditional paper, video instructions, virtual instructions and two types of virtual instructions combined with augmented reality in-situ projection. We have proven that using any type other than ''paper'' will shorten the learning time by approximately half. INDEX TERMS Assembly instructions, augmented reality (AR), ...

“…Increasing product complexity and growing numbers of product variants have an impact on the assembly difficulty. Several authors state that AR can be used to counteract those difficulties (Funk et al 2017;Holm et al 2017;Wójcicki 2014). In addition, AR can decrease the learning curve ) and supervise assembly steps by suggesting corrective measures once a mistake is detected (Mura et al 2016).…”

“…After that, the AR system slowed them down. Holm et al (2017) tried to tackle that problem of inflexible guidance by providing adaptive instruction through AR. Depending on the stored competence level of the user and the real-time completion time of a task, the visual guidance is adapted from basic text instructions to 3D animations.…”

“…It is still restricted by technological challenges. Before conducting (long-term) studies in industrial settings, the weight of HMDs and the field of view was often criticised (Holm et al 2017;Schlagowski et al 2017;Makris et al 2016;Maly et al 2016;Mura et al 2016). Yet, ergonomics is not limited to the wear-ability of HMDs, but also on how ergonomic the user interface is.…”
