    The Arena: An lndoor Mixed Reality Space
    (The Eurographics Association, 2021) Dias, José Miguel Salles; Bastos, Rafael; Santos, Pedro; Monteiro, Luís; Canhoto, Joaquim; Carriço, Luís and Correia, Nuno and Antunes, Pedro and Jorge, Joaquim
    ln this paper we introduce the Arena, an indoor space for mobile mixed reality interaction. The Arena, includes a new user tracking system appropriate for ARJMR applications anda new Too/kit oriented to the augmented and mixed reality applications developer, the MX Too/kit. This too/kit is defined at a somewhat higher abstraction levei, by hiding from the programmer low levei implementation details and facilitating ARJMR objectoriented programming. The system handles in a uniform way, video input, video output (for head-sefs and monitors), sound aurelisation and Multimodal Human-Computer Interaction in ARJMR, including, tangible interfaces, speech recognition and gesture recognition.

    ARTIC: Augmented Reality Tangible Interface by Color Evaluation
    (The Eurographics Association, 2021) Dias, José Miguel Salles; Jamal, Nádia; Bastos, Rafael; Silva, Pedro; Carriço, Luís and Correia, Nuno and Antunes, Pedro and Jorge, Joaquim
    We present ARTIC, a novel tangible interface that offers 3D user interaction which can be explored in the con· text of Augmented and Mixed Reality. Our system consists in tracking a portable artifact based on color evalua· tion by computer vision, and use it as a 3D input device. Using vision-based techniques, we are able to detect and track the motion of a physical object through color analysis and segmentation, and then perform virtual interactivity to the user, which is extremely important in a Tangible Augmented Reality approach.
