Blo - multimodal interaction with user's forced exhalation

“Blo” is a multifunctional digital input device that accepts forced exhalation from mouth and its variations thus adding a new dimension to the human-computer and human-machine interaction. This new attempt has a potential to tap our natural actions to address certain challenges faced in conventional methodologies and introduces new possibilities of applications. This paper introduces you to the concept of Blo in a detailed way and discusses the various scenarios in which Blo can be used.
