Biosensing for Human Computer Interactions

June 14th, 2014 25 comments

After the analysis of “Visualizing techniques with plants”, we will explore interactions for human computer interaction (HCI) through plants. The objectives of this research are revealing technical approaches and which kind of interaction can be performed.

Interactions between humans and computer is usually implemented by sensors. In 2009 Dan Saffer defined a sensor for human computer interaction like this:


A sensor is typically an electrical or electronic component whose job is to detect changes in the environment [Saffer2009, page 13].


We are surrounded by plants and plants are able to sense changes in our environment. The increasing problem with our environment forces us to reconsider our usage of technology. Hybrid solutions between natural resources and our current technology is able to decrease our current environmental issues [ICC2007, pages 15-21]. For this reason, it is obvious to explore the plant abilities of sensing for HCI. The sensor belongs to the basic components of any gestural system, which is used in HCI applications [Saffer2009, page 13]. In our context we replace the common electronic sensor with a plant. An additional electronic circuit translates these bio signals into electronic computer-readable signals. Accordingly to this approach, the gestural system is completed again. Read more...

Can Plants be a Music Instrument?

Make music with plants

During my research on Human Plant Interfaces I figured out music and sound is a very often used expression for this kind of interaction. As far as I know John Lifton and Richard Lowenberg are one of the first artists that used plants for creating a soundscape. Their installation "Green Music", created for the much discussed movie "The Secret Life of Plants" (movie), uses the approach of bio sensing and converts the signals to synthesized sounds. The visitors can interact with the plants via touch for changing the pitch level of a sound. Read more...
