This research aimed to explore the integration of Virtual reality technology in ergonomically testing automotive interior designs. This objective was aimed at ensuring that such technology could be used to ameliorate user comfort through controlled simulations. Existing ergonomic testing methods are often limited when it comes to recreating actual driving situations and quickly repeating design improvements. VR could be used as a solution because its ergonomically tested simulation can be used to provide users with the real experience of driving. The users can be observed while they experience it and asked for their feedback. For this research, an interactive VR environment imitating a 10-minute-long trip through traffic and changing road conditions was created. It was populated by ten users, concatenated equally in men and women, both aged 20-35, representing approximate demographics of workers in the automotive production industry. Participants of the research were asked to use
Researchers have developed SPINDLE, a pioneering robotic rehabilitation system. Combining virtual reality (VR) with customized resistance training, SPINDLE offers personalized therapy to enhance strength and dexterity for activities of daily living (ADLs). Its adaptability and potential for home use represent a major advancement in tremor rehabilitation, with broader healthcare implications.
Researchers worldwide are currently working on the next evolution of communication networks, called “beyond 5G” or 6G networks. To enable the near-instantaneous communication needed for applications like augmented reality or the remote control of surgical robots, ultra-high data speeds will be needed on wireless channels. In a study published recently in IEICE Electronics Express, researchers from Osaka University and IMRA AMERICA have found a way to increase these data speeds by reducing the noise in the system through lasers.
A research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that was installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain’s electrical activity during the immersive VR interactions.
In the increasingly connected and digital world, businesses are sprinting to integrate technological advancements into their corporate fabric. This is evident with the emerging concept of “digital twinning.” Digital twins are virtual representations of real-world objects or systems used to digitally model performance, identify inefficiencies, and design solutions. This helps improve the “real world” product, reduces costs, and increases efficiency. However, this replication of a physical entity in the digital space is not without its challenges. One of the challenges that will become increasingly prevalent is the processing, storing, and transmitting of Controlled Unclassified Information (CUI). If CUI is not protected properly, an idea to save time, money, and effort could result in the loss of critical data. The Department of Defense's (DoD) CUI Program website defines CUI as “government-created or owned unclassified information that allows for, or requires, safeguarding and
Designing an automotive seat, it is required to perform a detailed study of anthropometry, which deals with measurement of human individuals and understanding human physical variations. It also requires application-based movement study of driver’s hands, feet’s & overall body movement. It is very difficult to design seat curvatures based on any static manikin-based software. We at VECV, have developed a new concept using mixed reality VR technology to capture all body movements for designing best in class seat curvature to accommodate variety of drivers with different body types. We have designed a specialized static bunk, which has a wide range of seat, steering and ABC paddle adjustments, which are integrated with virtual data. We use to study and capture the data of driving position and other ergonomic postures of wide range of people with different body types on this static bunk according to their comfortable driving posture. In this comfortable driving posture, user is immersed in
A new washable wireless smart textile technology has potential uses in virtual reality and American Sign Language.
Engineers at the University of California San Diego have developed electronic “stickers” that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces. That makes them versatile for a wide range of applications, from arming robots with a sense of touch to elevating the immersive experience of VR and AR, making biomedical devices smarter, monitoring the safety of industrial equipment, and improving the accuracy and efficiency of inventory management in warehouses.
From the past few years, there is a pressing need for implementation of automatic in-vehicle safety systems to avoid vehicle crashes and fatalities. Development of autonomous emergency braking systems (AEBS) to detect and avoid collisions in such critical moments is of paramount importance. In this paper, AEBS is developed for a four-wheeler system that aims to detect vehicles and controls the ego vehicle based on the expected stooping distance (ESD). This control system aims to react based on the real-time relative distance & speed of the ego vehicle to actuate appropriate braking force. Control systems developed in Altair Activate are co-simulated with CARLA, a virtual reality simulator for autonomous driving research. Various scenarios including low and high-speed car to car motion, urban high and low traffic density environments are simulated to study the robustness of the control system. Further, studies are conducted to evaluate the effectiveness of the systems by varying the
Direct debugging of a vertical takeoff and landing (VTOL) fixed-wing aircraft’s control system can easily result in risk and personnel damage. It is effectively to employ simulation and numerical methods to validate control performance. In this paper, the attitude stabilization controller for VTOL fixed-wing aircraft is designed, and the controller performance is verified by MATLAB and visual simulation software, which significantly increases designed efficiency and safety of the controller. In detail, we first develop the VTOL fixed-wing aircraft’s six degrees of freedom kinematics and dynamics models using Simulink module, and the cascade PID control technique is applied to the VTOL aircraft’s attitude stabilization control. Then the visual simulation program records the flight data and displays the flight course and condition, which can validate the designed controller performance effectively. It can be concluded that the designed VTOL fixed-wing aircraft control visual simulation
Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses. Smart contact lenses are high-tech contact lenses capable of displaying visible information on our corneas and can be used to access augmented reality.
For almost as long as it’s been a concept, NASA has been on the cutting edge of virtual reality (VR) technology. However, the space has seen a renaissance since the bulky headsets of the 1990s. Several high-profile companies now use VR for immersive video games and virtual chat rooms, but, to some, this technology has a use beyond entertainment.
More pixels! This is a major trend in the display industry. The benefits of 8K or higher resolution TVs may be debatable. For eye catching applications such as AR/VR glasses, more and therefore smaller pixels are required for technical feasibility. Screen door effects and pixel inhomogeneities are easily visible and disturbing for the user on displays that sit closely to the viewer’s eye. μ-LEDs are considered an innovative technology for very high resolutions with pixel sizes of less than 10 μm and equally small pixel pitches. In general, they have the potential to be a groundbreaking display technology – provided production challenges can be solved. Just like OLED displays, μ-LEDs are an emissive display technology, i.e., each single subpixel is in itself a light source. Luminance and color variations between the individual pixels are likely. As this strongly influences the visual quality of the displays, a quality control and calibration of the displays is necessary not only in the
A research team from the National University of Singapore (NUS) Faculty of Science, led by Professor Liu Xiaogang from the Department of Chemistry, has developed a 3D imaging sensor that has an extremely high angular resolution — it can distinguish points of an object separated by an angular distance, of as little as 0.0018°. The sensor operates on a unique angle-to-color conversion principle, allowing it to detect 3D light fields across the X-ray to visible light spectrum.
ABSTRACT This paper discusses the design and implementation of an interactive mixed reality cockpit that enhances Soldier-vehicle interaction by providing a 360-degree situational awareness system. The cockpit uses indirect vision, where cameras outside the vehicle provide a video feed of the surroundings to the cockpit. The cockpit also includes a virtual information dashboard that displays real-time information about the vehicle, mission, and crew status. The visualization of the dashboard is based on past research in information visualization, allowing Soldiers to quickly assess their operational state. The paper presents the results of a usability study on the effectiveness of the mixed reality cockpit, which compared the Vitreous interface, a Soldier-centered mixed reality head-mounted display, with two other interface and display technologies. The study found that the Vitreous UI resulted in better driving performance and better subjective evaluation of the ability to actively
Crew Station design in the physical realm is complex and expensive due to the cost of fabrication and the time required to reconfigure necessary hardware to conduct studies for human factors and optimization of space claim. However, recent advances in Virtual Reality (VR) and hand tracking technologies have enabled a paradigm shift to the process. The Ground Vehicle System Center has developed an innovative approach using VR technologies to enable a trade space exploration capability which provides crews the ability to place touchscreens and switch panels as desired, then lock them into place to perform a fully recorded simulation of operating the vehicle through a virtual terrain, maneuvering through firing points and engaging moving and static targets during virtual night and day missions with simulated sensor effects for infrared and night vision. Human factors are explored and studied using hand tracking which enables operators to check reach by interacting with virtual components
ABSTRACT As technology continues to improve at a rapid pace, many organizations are attempting to define their place within this modern age and the Department of Defense (DoD) is no exception. The DoD’s primary focus on modernization ensures that its design, development, and sustainment of systems demonstrate unparalleled strength that outpaces our adversaries and continue to solidify our position quickly and efficiently as the world’s mightiest through fundamental change. Digital Engineering (DE) is the foundation of that fundamental change. Speed-to-Warfighter, reliability, maintainability, resiliency, and performance are all improved through DE techniques. Accelerating technical integration by connecting once isolated data to a digital thread encompassing all domains, and further facilitating the evolution of the traditional approach/processes into an effective DE strategy. DE’s goal supports a reduction of inefficient process/procedures/communications that traditionally can yield
Thanks to artificial intelligence (AI), augmented reality (AR) has long shaped product development across a variety of areas, including the medtech industry. Use of these trends can significantly improve diagnostics and, therefore, treatment. This applies, for example, to surgery and to the adjustment of medication regimens to reflect the patient’s needs. To do this, medical practitioners use recommendations provided by AI, which in turn draws on a broad digital database.
MIT researchers have built an augmented reality (AR) headset that gives the wearer X-ray vision. The headset combines computer vision and wireless perception to automatically locate a specific item that is hidden from view, perhaps inside a box or under a pile, and then guide the user to retrieve it.
Recent events have shown that challenges to the global status quo can arise rapidly, making it imperative that military manufacturers remain agile and prepared to meet new circumstances as they emerge. As author Jim Pattison succinctly stated: “No matter what business you are in, there is change, and it's happening pretty quickly.” The challenges posed to military manufacturers include shorter design and production timetables, the need for greater efficiency in parts replacement and material usage, and an accelerated time to market; challenges that must be met with every technological tool available. The current revolution in manufacturing driven by digital technologies, is transforming the global production landscape. While artificial intelligence, augmented reality and the Industrial Internet of Things (IIoT) are increasing production efficiency and time to market, 3D scanning still has not been exploited by aerospace and defense manufacturers for its full potential to do the same.
The researchers from the University of Cambridge have developed an algorithm, which gives an accurate measurement of tree diameter, an important measurement used by scientists to monitor forest health and levels of carbon sequestration. The algorithm uses low-cost, low-resolution LiDAR sensors that are incorporated into many mobile phones, and provides results that are just as accurate, but much faster, than manual measurement techniques.
Technology capable of replicating the sense of touch — also known as haptic feedback — can greatly enhance human-computer and human-robot interfaces for applications such as medical rehabilitation and virtual reality. A soft artificial skin was developed that provides haptic feedback and, using a self-sensing mechanism, has the potential to instantaneously adapt to a wearer’s movements.
Industrial vehicles such as forklifts, cranes and tractors have come a long way in terms of applying technology, enhancing performance with improved operation and safety. With the advancements in computer vision, robotics and artificial intelligence (AI), these vehicles now are equipped with functionality that utilizes information to support and optimize performance. One of the key enablers of these advances is the integration of machine learning (ML) derived platforms and powerful computers, neural processing units and cameras integrated into the digital system. System designers and OEMs can get started with AI and computer vision using just a standard Ethernet camera and a Cortex A35 dual- or quad-core next-generation display. Using the detection and recognition of objects, designers can implement and train neural networks to realize new solutions for process guidance, automation, augmented reality and operator awareness. For example, the dual-core CCpilot V700 from CrossControl can
The way in which businesses, enterprises, industry leaders, and consumers utilize technology for everyday tasks is set to undergo one of the most drastic evolutions ever. Just a few short years ago it was nearly impossible to think any other technology could have a greater impact than networked computers, the Internet, or even mobile computing, but now technologies like artificial intelligence (AI), Internet of Things (IoT) and AR/VR are being hyped more than ever.
Despite recent supply-chain disruptions, semiconductor buyers are increasingly spoiled for choice when it comes to chip manufacturers. From a chipmaker’s perspective competing for “sockets” in the next gadget — whether it be a mobile phone a VR headset, or an EV — is a game of speed. As a result, competition among producers continued to reduce product development and delivery times — once years to now a few short months.
Rolls-Royce is leading an ambitious decarbonisation strategy, aiming to become a net zero carbon company across their value chain by 2050. Manufacturing and production are at the core of this strategy. For instance, Rolls-Royce expects their production site in Bristol, UK, to be the first Rolls-Royce facility to achieve net zero carbon status in 2022 and do so without using carbon offsets.
Current simulation tools can assist in expediting the development and validation of powertrain control systems compared to traditional methods that exclusively use physical testing. In this study, a co-simulation platform has been developed by connecting Matlab/Simulink, IPG CarMaker, GT-Suite, and PTV Vissim together to create a virtual calibration and validation environment. The purpose of developing this platform is to save time and reduce costs during vehicle testing by largely replacing the calibration and robustness evaluation carried out on physical vehicles with a simulation-based approach. The platform constructs a virtual environment that replicates the local road network as well as populates the roads with a randomly generated traffic pattern that the simulated vehicle can interact with. By combining the strengths of each software listed above, the developed virtual environment can provide realistic drive scenarios for testing new vehicle control algorithms. One of the
