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...

Visualizing techniques with plants for Interaction Design

June 2nd, 2014 20 comments

Nowadays information becomes more pervasive and crucial in a knowledge-based society [ZhaoMoere2008]. Therefore it is important for a society to develop an easy access to communicate meaning and functionality of information [MoereOffenhuber2009]. The easiest information access exists in our natural everyday physical environment. Public screens attempt to address this task. Unfortunately, current public screens hold several disadvantages for our public environment. They need a dedicated flat surface, illuminating their surrounded environments, and address only the visual sense. Furthermore, people often associate public screens with advertisement and pay less attention to them [MoereOffenhuber2009]. Therefore, it is rational to investigate information displays beyond the traditional screen-based visualizations. Plants are one of these objects, which are omnipresent in our daily physical environment. For this reason, data sculptures with plants might be an alternative approach to solve the problems of public screens and reach wide audiences. The following artworks are interpreted as the next development steps of the contemporary plant-based artworks from chapter 2.3 “Ethnobotany”. In this stage electronic and digital technology is applied to plants.

Within the scope of my research I will present a qualitative evaluation of visualizing techniques with plants. The evaluation model is based on the comparison methods developed by Andrew Vande Moere, Dietmar Offenhuber [MoereOffenhuber2009], and as well as Matthew Brehmer, and Tamara Munzner (2013) [BrehmerMunzer]. The evaluation result reveals their visual encoding techniques, and which characteristic of data they visualize. Furthermore, the outcome assigns approaches of creating more intriguing, and easy memorable visualizations. 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...

Plant Colour Patterns

One week ago I published a blog post about links and places for Physical Computing in Germany. Today I decided to do the same for plant-based stuff. Hopefully, I get more organized in the future and maybe helpful for some others, too. Please feel free to add some others resources as comment. ThX!

Physical computing Linksammlug

Für einen Kollegen mußte ich neulich eine kleine Linksammlung über die Maker Szene in Deutschland zusammen stellen. Die Liste ist sicherlich nicht vollständig, liefert dennoch meiner Meinung eine gute Orientierungshilfe in Sachen Physical Computing. Bin um jede weitere Quelle sehr dankbar, daher bitte benutzt die Kommentar Funktion und ergänzt diesen Artikel mit weiteren Quellen bzw. Anlaufstellen.
