This prototype is completely autonomous and projects the information on the real world, so that it is visible for a group of users. The system was built using mostly low-cost hardware (Raspberry Pi, plus a camera module and an inertial measurement unit), and the software was developed using C++ and OpenGL ES 2.0.Humancentered computingMixed / augmented realityComputing methodologiesCamera calibrationComputer systems organizationEmbedded hardwareExperiences From the Development of a Prototype of an Spatial Augmented Reality System10.2312/ceig.2018115879-82
