Right: the same image converted to a hologram. Credit: Jana Skirnewskaja Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by ‘seeing through’ objects to alert of potential hazards without distracting the driver. The technology, developed by researchers from the University of Cambridge, the University of Oxford, and University College London (UCL), is based on LiDAR (light detection and ranging), and uses LiDAR data to create ultra high-definition holographic representations of road objects which are beamed directly to the driver’s eyes, instead of 2D windscreen projections used in most head-up displays. While the technology has not yet been tested in a car, early tests, based on data collected from a busy street in central London, showed that the holographic images appear in the driver’s field of view according to their actual position, creating an augmented reality. This could be particularly useful where objects such as road signs are hidden by large trees or trucks, for example, allowing the driver to ‘see through’ visual obstructions. The results are reported in the journal Optics Express. “Head-up displays are being incorporated into connected vehicles, and usually project information such as speed or fuel levels directly onto the windscreen in front of the driver, who must keep their eyes on the road,” said lead author Jana Skirnewskaja, a PhD candidate from Cambridge’s Department of Engineering. “However, we wanted to go a step further by representing real objects in as panoramic 3D projections.” Skirnewskaja and her colleagues based their system on LiDAR, a remote sensing method that works by sending out a laser pulse to measure the distance between the scanner and an object. LiDAR is commonly used in agriculture, archaeology and geography, but it is also being trialed in autonomous vehicles for obstacle detection. Using LiDAR, the researchers scanned Malet Street, a busy street on the UCL campus in central London. Co-author Phil Wilkes, a geographer who normally uses LiDAR to scan tropical forests, scanned the whole street using a technique called terrestrial laser scanning. Millions of pulses were sent out from multiple positions along Malet Street. The LiDAR data was then combined with point cloud data, building up a 3D model. “This way, we can stitch the scans together, building a whole scene, which doesn’t only capture trees, but cars, trucks, people, signs, and everything else you would see on a typical city street,” said Wilkes. “Although the data we captured was from a stationary platform, it’s similar to the sensors that will be in the next generation of autonomous or semi-autonomous vehicles.” When the 3D model of Malet St was completed, the researchers then transformed various objects on the street into holographic projections.https://scitechdaily.com/ultra-hd-3d-holographic-head-up-display-could-improve-road-safety/

Health workers who decline vaccine may be redeployed under proposal Health workers who decline to take a COVID-19 vaccine could be redeployed to other parts of the HSE under a new proposal. According to the HSE it employs 67,000 staff directly and another 35,000 people are employed by agencies funded by the service. Exact figures in relation to the number of healthcare workers working in private facilities across the country aren’t available. Health workers who decline to take a COVID-19 vaccine could be redeployed to other parts of the HSE under a new proposal. Pic: ULISES RUIZ/AFP via Getty Images Currently, there is no mandatory requirement for healthcare workers to take a vaccine , although uptake so far has been high. According to recent vaccination data from the HSE, 351,935 vaccine doses have been administered to frontline healthcare workers. It says that 256,044 first vaccine doses were given to healthcare workers while 95,891 second doses have already been administered. According to the HSE it employs 67,000 staff directly and another 35,000 people are employed by agencies funded by the service. Pic: Getty Images Although the uptake among frontline healthcare workers has, so far, been high, plans are reportedly in the works to accommodate those who do not want to be vaccinated. The HSE is said to be looking at proposals to redeploy staff to other parts of he health service if they decline to take a vaccine. Extra.ie has contacted the HSE in relation to the proposal. Although the uptake among frontline healthcare workers has, so far, been high, plans are reportedly in the works to accommodate those who do not want to be vaccinated. Pic: Getty Images The proposal would see a risk-assessment carried out for the each staff member who declines the vaccine, which would then form the basis for a decision on redeployment, according to reports. There are expected to be exceptions for redeployment in cases where staffing is already too low to avoid loss of another staff member or in cases where a person has a specialised qualification. The Health Information and Quality Authority has already proposed that staff who refuse a vaccine should be testing, additional personal protective equipment, information about vaccines and dialogue.https://extra.ie/2021/05/06/news/irish-news/health-workers-decline-vaccine
