Augmented Reality

Home » Services » Digital Engineering » Augmented Reality
Augmented reality is the technology that expands our physical world, adding layers of digital information onto it. AR appears in direct view of an existing environment and adds sounds, videos, graphics to it.
AR apps typically connect digital animation to a special ‘marker’, or with the help of GPS in phones pinpoint the location. Augmentation is happening in real time and within the context of the environment, for example, overlaying scores to a live feed sport events.

There are 4 types of augmented reality today:
•markerless AR
•marker-based AR
•projection-based AR
•superimposition-based AR

AR can be displayed on various devices: screens, glasses, handheld devices, mobile phones, head-mounted displays. It involves technologies like S.L.A.M. (simultaneous localization and mapping), depth tracking (briefly, a sensor data calculating the distance to the objects), and the following components:
•Cameras and sensors. Collecting data about user’s interactions and sending it for processing. Cameras on devices are scanning the surroundings and with this info, a device locates physical objects and generates 3D models.
•Processing. AR devices eventually should act like little computers, something modern smartphones already do. In the same manner, they require a CPU, a GPU, flash memory, RAM, Bluetooth/WiFi, a GPS, etc. to be able to measure speed, angle, direction, orientation in space, and so on.
•Projection. This refers to a miniature projector on AR headsets, which takes data from sensors and projects digital content (result of processing) onto a surface to view.
•Reflection. Some AR devices have mirrors to assist human eyes to view virtual images. Some have an “array of small curved mirrors” and some have a double-sided mirror to reflect light to a camera and to a user’s eye. The goal of such reflection paths is to perform a proper image alignment.

Types of Augmented Reality:
•Marker-based AR.
•Markerless AR. A.k.a. location-based or position-based augmented reality
•Projection-based AR
•Superimposition-based AR

The various potential areas for AR in TACTO can assist you include:
•Education: interactive models for learning and training purposes, from mathematics to chemistry.
•Medicine/healthcare: to help diagnose, monitor, train, localize, etc.
•Military: for advanced navigation, marking objects in real time.
Art / installations / visual arts / music.
•Tourism: data on destinations, sightseeing objects, navigation, and directions.
•Broadcasting: enhancing live events and event streaming by overlaying content.
•Industrial design: to visualize, calculate or model.
•Archaeology: AR allows archaeologists to formulate possible site configurations.
