“…Such an approach provides improvements in maintaining the instructions, but the impact on work performance is not as high [2]. On the other hand, changing the text instructions for static CAD images with motion diagrams improves the learning rate, but animating the CAD models improves it even further [3].…”

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), ...

“…CAI findings suggest adapting instructions to a user's current level of comprehension as well as using video, animation, and other media to improve information retention [1,6,18]. While multimedia demonstrations have been shown to increase task performance when compared to static text or verbal instructions, studies have found that demonstration information is not retained for long [16,23]. To address this limitation, Palmiter and Elkerton [16] suggest providing both text instructions and "well-placed" instructions to give the immediate benefits of multimedia while supporting retention.…”

We present a study that evaluates the effectiveness of augmenting on-screen instructions with micro-projection for manual task guidance unlike prior work, which replaced screen instructions with alternative modalities (e.g., headmounted displays). In our study, 30 participants completed 10 trials each of 11 manual tasks chosen to represent a set of common task-components (e.g., cutting, folding) found in many everyday activities such as crafts, cooking, and hobby electronics. Fifteen participants received only onscreen instructions, and 15 received both on-screen and micro-projected instructions. In contrast to prior work, which focused only on whole tasks, our study examines the benefit of augmenting common task instructions. The augmented instructions improved participants' performance overall; however, we show that in certain cases when projected guides and physical objects visually interfered, projected elements caused increased errors. Our results demonstrate that examining effectiveness at an instruction level is both useful and necessary, and provide insight into the design of systems that help users perform everyday tasks.

Figure 1. An overview of the range of 3D cues we created to help guide a user's movement. In (a), a user is shown a 2D arrow with a circle that moves in the horizontal plane, (b) shows a 3D arrow, (c) a 3D path where blue indicates the movement trajectory and (d) uses positive and negative spatial coloring with an arrow on the user's hand to indicate depth. ABSTRACTLightGuide is a system that explores a new approach to gesture guidance where we project guidance hints directly on a user's body. These projected hints guide the user in completing the desired motion with their body part which is particularly useful for performing movements that require accuracy and proper technique, such as during exercise or physical therapy. Our proof-of-concept implementation consists of a single low-cost depth camera and projector and we present four novel interaction techniques that are focused on guiding a user's hand in mid-air. Our visualizations are designed to incorporate both feedback and feedforward cues to help guide users through a range of movements. We quantify the performance of LightGuide in a user study comparing each of our on-body visualizations to hand animation videos on a computer display in both time and accuracy. Exceeding our expectations, participants performed movements with an average error of 21.6mm, nearly 85% more accurately than when guided by video.
