This course will focus on researching, designing, and defining Intangible Interactions together, and unveiling artistic potential in it. Intangible interactions are those that we engage in without involving direct physical contact. Some examples would be automatic toilets, shopping carts that stop rolling outside the shop, contactless thermometers, gesture-based interactions, theremin, artwork activated by your presence, and mid-air haptic experiences. Intangible interfaces don’t have a tangible form that explicitly instructs us how to interact with them, and these interactions utilize other forms of feedback than those we feel through touch. Hence, Intangible Interactions tend to be more nuanced rather than direct, and the system is intricately designed to read your intentions using sensors. While technologies used for intangible interaction–such as computer vision and sensors are now more available and accessible, knowledge around the design and implementation of effective intangible interactions is a much less explored subject. We will explore practical, artistic, and whimsical applications of intangible interaction and look at the ways it can enhance human-computer interactions in our everyday lives. For example, it can allow new ways to interact with educational exhibits, artifacts, and artworks. We will explore intangibility as a poetic medium that can open up possibilities for creating work that challenges human senses and perception. We will discuss what are cultural and social implications that we need to consider in designing intangible interactions—what does it mean for an interaction to be “intuitive” and what are some of the assumptions that are embedded into designs that we need to challenge? You will also be introduced to working with sound frequencies that are outside the hearable spectrum to create mid-air haptic feedback. Technical topics that will be discussed in the class include: non touch-based sensors including optical sensors; proximity sensing; presence detection; optimizing sensor readings on Arduino; extending capability of sensors with light pipes and lenses; body tracking with cameras; signals outside visible spectrums; environmental sensing; mid-air haptic. Assignments will include relatively small-scale production assignments, labs, thinking, ideating, and reading. For the final project, you will be prompted to conceptualize a project that is larger than a classroom scope. You will respond to a call-for-projects with a proposal along with a solid prototype for the project so you have fully fleshed materials to apply to resources such as grants and other opportunities in the near future. I want you to think big and equip yourself with practical and essential skills to build a sustainable art or design practice! A proposal writing workshop and structured peer reviews will be provided to support this process.
