Since the publications of Wikileaks and Edward Snowden, some of our worst worries became true. The Internet got infected by a few sources of power. Mass surveillance by governments and big corporates is the daily routine. People, who fight for transparency are chased (e.g. Netzpolitik.org, Eward Snowden, Aaron Swartz, and other whistle-blowers) or got into some weird trouble. For years, I have the feeling the public discussion about the importance of privacy is very abstract and disconnected for the normal "non-technic" crowd. Even more bad the Open Data movement in the US got also kinda stuck, because there does not exist any really benefit for a goverment to be transparent. Failures (through bad management or even corruption) could be found easier by journalist, but that is not the intent of a running government. However, Edward Snowden tried to explain the problem with the mass surveillance with his famous tweet, which should emphasize why privacy is important and a basic right for a democratic system.

A couple of months ago, I tinkered around with NodeJS on my local machine. After a while I got kinda addicted to the NodeJS Plattform for webservice (SOA) applications as well as Desktop Apps (Electron/NodeWebkit). Hence more complicated NodeJS experiments will start, I decided to set-up my own webserver environment for my (local) network with a Raspberry Pi 2 B. My tools of choice are:
- Raspian Jessie Lite from 2016-05-27
- GIT v2.1.4: Version control for source code
- NodeJS v6.2.0: for REST APIs and Websocket applications
- Nginx Webserver: Deliver static files, Reverse Proxy for NodeJS, and Load Balancing
- MySQL Server and Client: for Relational Databases
- PM2: NodeJS Process Manager for starting and stoping NodeJS Apps
- Nodeadmin: Admin Tool for MySQL (like PHPmyAdmin)
Let's get started:
Im Anfang Mai 2015 lud mich Myriel Milicevic für eine Gastvorlesung und anschließendem Workshop für Ihren Kurs Interfacing with Nature an der Hochschule Potsdam ein. Mein Themengebiet für diesen Tag waren die Artistic Human Plant Interfaces/Elektrobotanik. In der 90-120min Einführung bekamen die Studenten aus den Bereichen Produkt Design, Interface Design und Kommunikationsdesign einen ersten Eindruck, welche Überschneidungen zwischen Menschen und Pflanzen, sowie zwischen Pflanzen und Technologie auftauchen.
On May 2015, Myriel Milicevic invited me for a Guestlecture & Workshop on Artistic Human Plant Interfaces/Elektrobotanik for her Interfacing with Nature class at University of Applied Science Potsdam. The starting 90-120min lecture provided the students (in that case communication, product, and interface designer) an introduction about interfaces with plants. This includes viusal approaches as well as bio sensing projects.
During mid of 2013 until the beginning of 2014, Juliane Springsguth and me had the chance to develop a new game design hacking workshop format for teenagers (Mostly 8th graders around 13-15 years old) in cooperation with "Berufsorientierte Schulprojektwochen (BOP)" organized by the Media Education Institution WeTeK Berlin gGmbH.
Our objective was to generate a tangible and audiovisual output in shape of a Game (Art) installation during the workshop. Furthermore, our intention regarding those young participants was to empower them to express their ideas in a (media) technology driven environment. Officially the objective was that they get a first impression how a job as digital media worker could look like.
My Biosensing with Plants chapter is published in the book: The Green Thread Dialogues with the Vegetal World
Some findings of my master thesis about biosensing are published in the new book:
Edited by Patrícia Vieira; Monica Gagliano and John Ryan
Together with Christa Sommerer and Laurent Mignonneau, we wrote the chapter 13 The Art of Human to Plant Interaction. If you want to see videos of these featured Human Plant Interaction, please check: Biosensing for Human Computer Interactions
Please feel free to post your Feedback about our chapter!
For almost more than a year I wanted to write a tutorial about how to create a speaker on a leaf. Unfortunately, I found no time to write one. I think it is now time to show you the video as an example and provide you the links for built your own leaf speaker
For several years, I am really excited about Hannah Perner-Wilson aka Plusea's textile circuits. Fortunately, I could join her workshop during the Schmiede 2013 and applied her textile speaker to a lead of a plant. First experiment worked well with conductive thread, which kinda harmed the leaf structure. Therefore, we experimented with conductive ink, too. The result was much quiter noise.

Long time ago I started posting my last summary of my Twitter messages. It is always a nice way to reexperience the developments of a certain time period. For this reason my most important Twitter messages from Ocotber 2014 until January 2015. Read more...
The human perception responds positively on natural environments with many plants. Especially, during the seasons spring and autumn people are excited by the shape and colours of plants. The photo series “Season Patterns” is an artistic approach of capturing and documenting these feelings of beauty caused by nature [Schwepenhäuser2007, pages 70-71].
Previous landscape painters already tried to capture the broad range of natural elegance in their artworks. Their approaches were very often accurate in every detail of the landscape, but still the painters were not satisfied with their visual representations of the landscapes. For this reason, the photo series “Season Patterns” uses a visual abstract expression for representing the prettiness of nature and plants.
The theoretical and practical part of this thesis proposed techniques and applications for Human Plant Interfaces. The results of the qualitative analysis and the practical work exposed evidences for the relevance of the topic Human Plant Interaction.
The theoretical analysis pointed out that plants are a valid material for visualization applications. The applied techniques are heavily depending on the data characteristics. For long term data visualization the usage of plant displays with their changing appearance ability through plants growth is an appropriate tool. In contrast to this, visualizing real-time data requires a different approach. Simple data values or the visualizations of state changes in an interactive system can be performed through kinetic gestures of a plant (e.g. movement of branches). More complex data can be visualized with the help of projection mapping techniques. The physical size of these visualizations varied from small (table-size) to huge.
