Interactive Experience

Owing to increasing cases of sedentary lifestyles and their negative impact on health, practical solutions are needed to address the physical and mental wellbeing of citizens and to enhance their standard of living. Among the problems are premature mortality rates caused by physical inactivity, which leads to chronic diseases. Innovative solutions are needed to address many of the problems that we face as a society. Location-based games have been identified as effective solutions for increasing physical activity, enhancing social interaction, and exploration in urban environments. In this pilot study, we explore how to encourage active mobility (walking and cycling) through urban play by integrating technology into the built environment. We examined the usability of a web-based augmented reality application in providing interactive experience to users as they explored the urban environment looking for tasks. Overall, participants’ perceptions of the usability of the application were positive; they enjoyed how the application revealed the tasks at each location and all the checkpoints at the different locations had at least a couple of visitors. We present limitations and future research directions.

Today we life in the era of technology and information. Technology has become an important tools in human daily need and being used in every field of works, including advertisement. With the rapid development of technology, information can be accessed easily in faster speed and in higher quantity. In advertising, information is one of the most important element, we want our advertisement to contain information about our products and delivered in a fastest pace as possible with enough attraction element in it, also we want our advertisement to reach as many people as possible. Ironically, in the era of technology, we still using papers in our advertisement like posters, brochures, booklets, and many other printed promotional tools. The high demand for papers gives negative impact for nature, not only for the trees and forest, but also for the ecosystem. The rapid development of technology has given us so many new alternatives media in advertising, one of them is augmented reality. Augmented reality have a lot of potential to use in many fields of works including advertising. This study attempts to give comparisons between conventional media and Augmented Reality in advertising. The interesting thing of this study is to learn the weakness and the strength of paper media and Augmented Reality in advertising, and to learn how technology can be used indirectly for preserving nature.

Spinal Navigation

Abstract Background Conventional spinal navigation solutions have been criticized for having a negative impact on time in the operating room and workflow. AR navigation could potentially alleviate some of these concerns while retaining the benefits of navigated spine surgery. The objective of this study is to summarize the current evidence for using augmented reality (AR) navigation in spine surgery. Methods We performed a systematic review to explore the current evidence for using AR navigation in spine surgery. PubMed and Web of Science were searched from database inception to November 27, 2020, for data on the AR navigation solutions; the reported efficacy of the systems; and their impact on workflow, radiation, and cost-benefit relationships. Results In this systematic review, 28 studies were included in the final analysis. The main findings were superior workflow and non-inferior accuracy when comparing AR to free-hand (FH) or conventional surgical navigation techniques. A limited number of studies indicated decreased use of radiation. There were no studies reporting mortality, morbidity, or cost-benefit relationships. Conclusions AR provides a meaningful addition to FH surgery and traditional navigation methods for spine surgery. However, the current evidence base is limited and prospective studies on clinical outcomes and cost-benefit relationships are needed.

This paper describes the incorporation of realistic occlusion effects into mirror-based, stereoscopic co-location augmented reality display systems. By adding a light-blocking device in the form of an LCD panel underneath the semitransparent mirror, the view of the physical world can be selectively blocked out such that virtual objects can fully occlude physical objects. Furthermore, by discarding pixels of the virtual objects rendered on the reflected display, physical objects seen through the semitransparent mirror and the transmissive LCD panel appear to occlude these virtual objects. The governing principles of the approach are described, and two algorithmic approaches (model based and vision based) for scene reconstruction and the generation of the occlusion masks are presented. Finally, a prototype implementation of the system is presented.

Optical Camera Communication

In vehicular optical camera communication (VOCC) systems, LED panels are used to transmit visible light signals which are captured by cameras. The logic bits 1 and 0 are represented by the On and Off status of the LEDs in the panel. The bit error rate (BER) of the system is directly proportional to the distinguishability of the On and Off LEDs in the received LED panel images. The signal quality is commonly believed in telecommunications to improve with a higher transmitted power. Therefore, one might expect to get a lower BER in VOCC systems by simply using more powerful LED lights. However, this is not the case with VOCC systems. This paper shows that the LED distinguishability is simultaneously determined by two factors: The LED extinction ratio and LED interference. The former needs to be kept high and the latter kept low for better LED distinguishability. The problem is that both the extinction ratio and interference increase with the ratio of LED light to ambient light (L2A). Consequently, an optimal L2A ratio exists to achieve the optimal balance between the positive impact of the extinction ratio and the negative impact of the interference. This can bring about the lowest BER without changing the system’s data rate. In addition, this paper shows that the optimal L2A ratio varies according to the interval between the LEDs in a panel. We analyze the effect of the L2A ratio and LED interval on LED distinguishability. We then formulate a constrained optimization problem to find the optimal L2A ratios corresponding to different LED intervals. The simulation results verify the necessity of LED to ambient light ratio optimization as it can bring about the lowest BER without scarifying other aspects of the VOCC system.
