Building Wearables for Geology: An Operating System Approach

Wearable devices have emerged in the last years with new applications that provide user convenience. Healthcare, sports, safety are some examples of applications embedded in thousands of devices released in the last years. Wearable operating systems with different focus emerged together with wearable applications in order to make adjustments and optimizations of software and hardware. This paper presents a wearable operating systems discussion and shows the current challenges and wearable operating system inuence. We developed a wearable appliance for geology. The wearable contains a Head Mounted Display (HMD) assembled with Google Cardboard API and sensors connected to developments boards. For each system component was used different operating systems according to hardware and software available. The results indicate some trends for wearable operating systems.

Towards a Wearable Device for Monitoring Ecological Environments

Wearable devices have emerging in last years with diverse applications for provide user convenience. Health care, sports, safety are some examples of areas in which wearable devices have been applied. This paper describes an overview about wearable architectures found in the literature and presents a novel wearable for monitoring ecological environments. The wearable is composed of a Head-UP Display (HUD) assembled with Google Cardboard API and sensors connected to a development board. Our wearable device provides several functionalities such as distance measurement to objects and weather conditions monitoring. Camera and green lasers combined with a digital image processing algorithm are used to measure the distance to objects. Our system is evaluated in different development boards.

Towards a Low-Cost Augmented Reality Head-Mounted Display with Real-Time Eye Center Location Capability

The real-time detection of eye center location provides valuable information to be used in a wide range of applications such as face alignment, face recognition, human-computer interaction, device control for people with disabilities and users attention detection. Gaze tracking systems is another type of application that uses the eye center location to infer the direction of the users gaze. These systems can be applied to Augmented Reality (AR) Head-Mounted Displays (HMDs) in order to improve the User Experience. This work presents a low-cost AR HMD prototype with real-time eye center location capability. This work also presents an overview of Augmented Reality Head-Mounted Displays and methods for eye center location found in the literature. To assess our AR HMD prototype, we choose a state-of-the-art method for eye center location found in the literature and evaluate its real-time performance in different development boards.

Fast prototyping of an AR HUD based on google cardboard API

A Head-Up Display (HUD) prototype as tool for biologists is introduced in this work. The prototype contains two sensors to climate monitoring, a multi-point laser to infer objects distances and a smartphone to display information for users. CardBoad API has been used as an Augmented Reality platform. The HUD hardware was printed in 3D printer, sensors are connected in an Intel Galileo development board and the data communication is done through Bluetooth technology. Also, this work describes experiences obtained with prototype development.

Evaluation of Wearable Devices for Belt Conveyor Inspection Using Augmented Reality

Augmented Reality, Virtual Reality and Wearable computing are being used to enhance different production processes in various areas of industry, including mining. Inspecting belt conveyors is a task that puts the human at risk in addition to being time-consuming due to the extension of belt conveyors that reaches thousands of kilometers. The use of drones as a tele-inspection tool is already a feasible alternative. However, it requires a collaborative interface between pilot and inspector. This work evaluates two wearable interfaces of augmented reality as HCI alternatives to assist the drone pilot in the inspection. The goal is to validate the platforms for visualization of the images of the industrial environment. Thus, user studies were conducted to evaluate the impact of the use of these augmented reality interfaces in the accomplishment of the task. The results show the feasibility of these tools in external and internal environments.

A Low Cost Optical See-Through HMD - Do-It-Yourself

HMD that provides Virtual Reality and Augmented Reality capabilities are emerging in the last years. Manufacturers are seeking to design hardware that maximizes the field of view (FoV) and depth of field (DoF). On the other hand, we did not found a device that allows the variation of these parameters. This paper presents a model to build HMD using mirrors reflection. Our model allows the adjustment of the DoF. Consequently, the FoV also changes. Our prototype shows that the proposed feature is a feasible alternative. Furthermore, we present a simple and low-cost alternative for HMD development.

Development of low-cost robot manipulators for kinematic control practices

Nowadays, dropping out of engineering courses practically occurs in all universities worldwide. Over the past few years, the educational community has been recognizing active learning as a very effective learning method. This article discusses the educational experience associated with conception and development of a low-cost manipulator robot of six degrees of freedom (6-DOF) used to motivate undergraduate students of control and automation engineering and mechanical engineering who had attended robotics elements subject between 2012 and 2013. Moreover, this paper reports the activities executed by the students during this study, and also shows the students review about the methodology applied.
