This project is regarding the Motion controlled wheelchair for disabled. We are going to control motorized wheelchair using a head band having motion sensor and Arduino as controller. Problem: “often disabled who cannot walk find themselves being burden for their families or caretakers just for moving around the house. Disabled who are paralysed below head, who may not have functioning arms cannot control joystick controlled electric wheelchair.” This project is to solve their problem using a motion sensor to control their wheelchair. We are aiming towards building a more affordable, unique, low maintenance and available for all kind of head-controlled wheel chair.

Haji merupakan rukun Islam yang kelima yang wajib dilaksanakan oleh seorang muslim yang telah mampu melaksanakannya. Manasik haji pada dasarnya adalah memberikan pelajaran atau informasi mengenai tata cara melaksanakan ibadah haji, sehingga tidak hanya terbatas pada calon jama’ah haji, biasanya masyarakat beragama muslim mempelajari tata cara melaksanakan ibadah haji dengan menggunakan buku-buku atau dengan cara memperagakan langsung dengan cara mensimulasikan tata cara ibadah haji sesuai dengan kondisi yang sebenarnya. Namun banyak kalangan masyarakat muslim yang enggan mendalami manasik haji, dikarenakan beberapa hal seperti tidak adanya waktu, dan kurangnya minat mempelajari dikarenakan kurang menarik dan tidak praktis. Dari hal tersebut sehingga muncul ide untuk membuat aplikasi simulasi manasik haji berbasis virtual 3D, aplikasi ini berisi tentang simulasi untuk rukun haji. Aplikasi manasik haji berbasis virtual reality ini dirancang dan dibuat dengan menggunakan software 3Ds Max dan unity 3D Game Engine. Hasil penelitian berupa aplikasi manasik haji yang dapat menampilkan simulasi virtual reality, yang meliputi simulasi tiba di bandara, Wukuf di Arafah, Mabit di Muzdalifah, Mabit di Mina, Jumrah, Tawaf, Sa’i dan simulasi Tahallul. Dengan adanya aplikasi ini diharapkan akan terjadi peningkatan minat masyarakat dalam mempelajari tata cara pelaksanaan ibadah haji.Kata kunci : virtual reality, manasik haji, simulasi, 3D.

This chapter outlines the advantages of digital epigraphy in the context of the original monuments. It analyzes the perception of epigraphic publication of monuments, taking into account new technologies. 3DVR models can be created using architectural drawings and measurements (CAD and 3D modeling), 3D scanning, and Structure for Motion (SfM). These systems present different advantages and challenges, which are discussed. Current options for publication include VSim, 3D GIS, and Unity 3D platforms. The issues of peer review of publications and long-term preservation of data are addressed. The chapter concludes with a consideration of the issue of potentially misleading impressions given by 3DVR representations.

Currently an increasing number of head mounted displays (HMD) for virtual and augmented reality (VR/AR) are equipped with integrated eye trackers. Use cases of these integrated eye trackers include rendering optimization and gaze-based user interaction. In addition, visual attention in VR and AR is interesting for applied research based on eye tracking in cognitive or educational sciences for example. While some research toolkits for VR already exist, only a few target AR scenarios. In this work, we present an open-source eye tracking toolkit for reliable gaze data acquisition in AR based on Unity 3D and the Microsoft HoloLens 2, as well as an R package for seamless data analysis. Furthermore, we evaluate the spatial accuracy and precision of the integrated eye tracker for fixation targets with different distances and angles to the user (n=21). On average, we found that gaze estimates are reported with an angular accuracy of 0.83 degrees and a precision of 0.27 degrees while the user is resting, which is on par with state-of-the-art mobile eye trackers.

AbstractThe electric wheelchair gives more autonomy and facilitates movement for handicapped persons in the home or in a hospital. Among the problems faced by these persons are collision with obstacles, the doorway, the navigation in a hallway, and reaching the desired place. These problems are due to the difficult manipulation of an electric wheelchair, especially for persons with severe disabilities. Hence, we tried to add more functionality to the standard wheelchair in order to increase movement range, security, environment access, and comfort. In this context, we have developed an automatic control method for indoor navigation. The proposed control system is mounted on the electric wheelchair for the handicapped, developed in the research laboratory CEMLab (Control and Energy Management Laboratory-Tunisia). The proposed method is based on two fuzzy controllers that ensure target achievement and obstacle avoidance. Furthermore, an extended Kalman filter was used to provide precise measurements and more effective data fusion localization. In this paper, we present the simulation and experimental results of the wheelchair navigation system.
