Invoked Computing

Direct interaction with everyday objects augmented with artificial affordances may be an approach to HCI capable of leveraging natural human capabilities. Rich Gold described in the past ubiquitous computing as an “enchanted village” in which people discover hidden affordances in everyday objects that act as “human interface “prompt[s]” (R. Gold, “This is not a pipe.” Commun. ACM 36, July 1993.). In this project we explore the reverse scenario: a ubiquitous intelligence capable of discovering and instantiating affordances suggested by human beings (as mimicked actions and scenarios involving objects and drawings). Miming will prompt the ubiquitous computing environment to “condense” on the real object, by supplementing it with artificial affordances through common AR techniques. An example: taking a banana and bringing it closer to the ear. The gesture is clear enough: directional microphones and parametric speakers hidden in the room would make the banana function as a real handset on the spot.

In other words, the aim of the “invoked computing” project is to develop a multi-modal AR system able to turn everyday objects into computer interfaces / communication devices on the spot. To “invoke” an application, the user just needs to mimic a specific scenario. The system will try to recognize the suggested affordance and instantiate the represented function through AR techniques (another example: to invoke a laptop computer, the user could take a pizza box, open it and “tape” on its surface). We are interested here on developing a multi-modal AR system able to augment objects with video as well as sound using this interaction paradigm.

“[A] ubiquitous intelligence capable of discovering and instantiating affordances suggested by human beings” – i had to read that twice until my head wrapped around it…
