Technological advancement provides an increasing number and variety of solutions to interact with digital content. However, the complexity of the devices we use to interact with such content grows according to the users' needs as well as the complexity of the target interactions. This also includes all those tools designed to mediate touch interactions with virtual and/or remote environments, i.e., haptic interfaces and rendering techniques. We propose three hours of tutorials to discuss the technology, challenges, and perspective of haptic systems and rendering techniques for immersive human-computer interaction.
