Augmented reality at the service of engineers, technicians and workers. The helmet Daqri, connects workers to the surrounding work environment by providing useful information in real time to speed up and simplify work. All thanks to a series of sensors capable of registering and interacting in 360 degrees with what is happening outside and a "thermal" vision that simplifies the performance of some specific tasks: from the reconstruction of all the characteristics of a certain accessory to the control of a certain element, such as a valve. The worker is thus capable of evaluating, as if equipped with an X-ray view, tubes and machinery verifying the correct operation. The Daqri Smart Helmet, creates a complete map of the entire environment: from the structures that are being completed to those that have just been outlined. Recorded data can be digitally transferred to, and immediately shared, with the supplied camcorder and microphone. It is a helmet that can work without WiFi, Bluetooth or GPS connection; taking full advantage of the power of augmented reality (and 4D technology) and represents a perfect solution for every type of construction site; even the least accessible and, logistically, the most complex. The helmet allows you to receive and make video calls with the operating unit for real-time instructions and assignment of activities. We can also take photos and videos of a certain particular machine or job and then send them for confirmations or modification requests to our clients. Simplify worker training with training courses and tutorials that can be viewed digitally directly in the workplace. In the last year, it has been tested by more than 100 different companies from various sectors: from the aerospace sector to the construction industry to reach those that deal with extractions (oil, but not only).
