This paper introduces the Laboratory of Technologies\nfor Interaction (LaTIn) and briefly describes its current main\nprojects. The main focus of LaTIn has been developing new ways\nof human-machine interaction using computer vision techniques.\nThe projects are categorized according to the distance between\nthe human user and the machine being operated. For close\ndistances, appropriate for interaction with desktop computers for\nexample, we have developed eye-gaze based interfaces. For mid\nrange distances, we have built hand and body gestures interfaces\nthat are appropriate for virtual and augmented reality settings\nand, for large distances, we have developed novel multiple people\ntracking techniques that have been used for surveillance and\nmonitoring applications.
