December 4th, 2012

Die 6. Initiative des Internet und Gesellschaft Collaboratory, an welcher ich als Experte mitgearbeitet habe, hat den Abschlussbericht zum Thema “Innovation im digitalen Ökosystem” veröffentlicht. “Innovation ist kein technischer Vorgang, sondern ein komplexer sozialer Prozess, in dem ökonomische Interessen, gesellschaftliche und betriebliche Kräfteverhältnisse, kulturelle Normen und Wertvorstellungen und andere sogenannte „weiche“ Faktoren die entscheidende Rolle spielen.

Design Thinking: An Innovative Concept for Developing User-Centered Software

September 20th, 2012

I wrote with Design Thinking colleagues a book chapter for “Software for the People” (Springer Verlag, Heidelberg, 2012). The chapter could be downloaded here (Springer login is required).

The abstract gives an overview about the chapter “Design Thinking: An Innovative Concept for Developing User-Centered Software“: “In times of economic crisis and rapid technological change, innovation is necessary for competitive advantage and successful business. Design processes and tools are one way to create innovative solutions. This article describes the emergence of design thinking in business and focuses on the four key elements of design thinking in detail: the iterative process, multidisciplinary teams, creative space and designer’s mindset. The limitations and potentials of design thinking are also discussed. Read the rest of this entry »

Hack things better with sugru

July 29th, 2010

I waited some weeks for my personal sugru I ordered here. I’ve been very excited to getting started with sugru and to “hack” my first things.

What is sugru? The appropriate wikipedia article defines sugru as follows:

“Sugru is the brand name for a patented, multi-purpose, non-slumping variant of silicone that resembles modeling clay. Read the rest of this entry »

Radio Frequency Identification Reading By Using Error Correcting Codes On Sets Of Tags

March 17th, 2010

In 2008 i worked on a 3 day Think Tank at SAP Research. The result of our postprocessing was an US and China patent named “RADIO FREQUENCY IDENTIFICATION READING BY USING ERROR CORRECTING CODES ON SETS OF TAGS” which i want to indroduce here shortly:

A method and a system are described for improved reading of Radio Frequency Identification (RFID) tags using correcting codes on sets of electronic tags. In one embodiment, information is requested from each of a set of electronic tags. The information includes an identification code and a portion of a codeword, the codeword contains a coded message with identification codes of all tags in the set. The information is received from a subset of the set of tags. Portions of the codeword from the received tag information of the subset of tags are assembled. The coded message is constructed from the assembled portions of the codeword. Finally, individually receiving information from a remaining set of the tags in the set of tags. In one embodiment, the system includes a set of electronic tags and a reading device to request and receive information from each of the set of electronic tags. The information includes an identification code and a portion of a codeword, the codeword contains a coded message with identification codes of all tags in the set. In addition, the system includes a decoding component to decode a number of assembled portions of the codeword and construct the coded message with the identification codes of all tags in the set. An enterprise system processes the received information from all tags in the set.

The entire patent could be found here. An entire PDF with illustrations can be found here.

Why you sometimes have to go back in the Design Thinking process just to come up with the same solution

March 15th, 2010

This is a repost of an article posted on the HPI d.school blog by Felix and me during the workshop “Innovation in early education – leveraging diverse cultural backgrounds”.

Ok, so we all know that sometimes you need to go back in the design thinking process. Maybe during testing you realize that your prototype is just not working or its fixing the wrong problem. You might want to go back to brainstorming to come up with something different, that does fix the right problem and fixes it in the right way. It seems like a reasonable thing to do. If something doesn’t work, come up with something else!
Today (Workshop day IV), however, we experienced a situation where we had to go back to the beginning of ideation. Maybe even to Point of View. So we went back and went through “Point of View” and “Ideation” again. Just to end up with the same solution we had before. So what happened? What was different now?

Unexpected AWS S3 monthly statement

December 16th, 2009

At our company we are using Amazon S3 as data storage for several use cases. For debugging our services and watching traffic in/out to the S3 buckets, S3 logging on several buckets have been active. Within the bill of november, the PUT, COPY, POST, or LIST requests have literally “exploded”. Amazon charges those requests with $0.01 per 1,000 requests. In our case, the monthly statement was higher by factor 20, case we activated S3 logging on our buckets!

So be careful if you activate S3 bucket logging, your the PUT, COPY, POST, or LIST requests will be higher and you will be charged for them, although your are logging within the S3 infrastructure to another bucket.

At this point i want to recommend a nice S3 GUI tool for managing your S3 infrstructure: S3 Bucketexplorer

85 Prozent der Kandidaten zur Bundestagswahl 2009 im Netz

September 22nd, 2009

270px-Bundestag

Bei der Wahl zum 17. Deutschen Bundestag am 27. September 2009 sind etwa 62 Millionen Deutsche wahlberechtigt. 3556 Kandidatinnen und Kandidaten bewerben sich am 27. September um einen Sitz im Bundestag. „Wen wählen?“ fragen sich heute noch viele Menschen, denn immer mehr Wähler entscheiden sich immer kurzfristiger. „Etwa 40 Prozent beschäftigen sich erst in den letzten zwei Wochen mit der Wahl und entscheiden dann, für welche Partei sie stimmen – oft auch erst am Wahltag“, sagt Prof. Dr. Frank Brettschneider, Politologe an der Universität Hohenheim.

Eine Analyse der Volz Innovation GmbH zeigt, dass 3050 Kandidatinnen und Kandidaten der Bundestagswahl 2009 (rund 85%) im Internet präsent sind und so die Meinungsbildung der Wähler zusätzlich zu den Internetpräsenzen ihrer Parteien unterstützen. Die „Online-Quote“ der Bewerber um die Mandate unterscheidet sich allerdings erheblich zwischen den Parteien selbst. Die CSU ist die einzige große Partei, bei der alle Kandidaten online zu finden sind. Unter den kleinen Parteien trifft dies nur für die PBC (Partei Bibeltreuer Christen), die Freie Union und die Freien Wähler Deutschland (FWD) in Brandenburg zu. Die Schlusslichter bilden die Kandidaten der Deutschen Kommunistischen Partei (DKP) und des Zentrums, von welchen weniger als ein Fünftel Informationen über sich im Internet bereitstellen.

Informationen über die Kandidatinnen und Kandidaten der kleinen Parteien können oft nur über Kandidatenverzeichnisse wie abgeordnetenwatch.de gefunden werden. Dies ist bei über 80% der Kandidaten der Bayernpartei (BP) und der FWD der Fall. Die besten Informationen zu rund 190 Kandidaten der im Parlament vertretenen Parteien finden sich bei wahl.de. Über 60% der zur Wahl stehenden Personen nehmen den Aufwand eines eigenen Internet-Angebotes in Kauf, welches dann entweder unter eigenen Internet-Adressen oder auf Unterseiten von Internet-Adressen ihrer Partei zu finden ist.

Die einzelnen Internetauftritte sind oft nur schwer zu finden. Dies zeigt auf, dass nur wenige Bundestagskandidaten eine Suchmaschinenoptimierung vornehmen, um bei den großen Suchmaschinen unter den ersten Suchergebnissen zu stehen. Zur Demonstration des neuen Internetdienst KNOXOS (www.knoxos.com), der sich auf die Suche in selbstdefinierten Teilen des Web konzentriert, hat die Volz Innovation GmbH die Liste der Kandidatenwebseiten zusammengetragen und deren Inhalte in KNOXOS durchsuchbar gemacht.

Damit steht eine präzise Suchmaschine für die Informationen auf den Startseiten der Kandidatinnen und Kandidaten zur Verfügung, welche die eigene Wahlentscheidung unterstützen kann. KNOXOS zeigt darüber hinaus immer aktuell auf, welche Anstrengungen die Kandidaten in dieser letzten „heißen“ Woche vor der Wahl auf sich nehmen. Viele Kandidaten berichten online über Ihre öffentlichen Auftritte und nehmen Stellung zu Fragen der Wähler.

KNOXOS (www.knoxos.com) ist ein neuer Internetdienst, der interessante Inhalte im Web für seine Nutzer beobachtet und durchsuchbar macht. KNOXOS zeigt gefundene Aktualisierungen in einer Änderungsansicht sofort an. KNOXOS hilft dabei, im Web nichts mehr zu verpassen und alles wieder zu finden.

KNOXOS ist ein Internet-Dienst der Volz Innovation GmbH (www.volzinnovation.com) und wurde im Frühjahr 2009 im Gründerwettbewerb Multimedia des Bundesministerium für Wirtschaft und Technologie (BMWi) ausgezeichnet. Die neuartige Suchtechnologie in KNOXOS wurde zum Teil im Forschungsprogramm THESEUS entwickelt. THESEUS (www.theseus-programm.de) ist ein deutsches Forschungsprogramm mit dem Ziel, eine neue internetbasierte Wissensinfrastruktur zu entwickeln.

New Mechanism to Clean your Mobile Device

August 23rd, 2009

Recently, my friend Markus and I developed a prototype and filed a utility patent for a cleaning mechanism for mobile devices. The mechanism is integrated into the box that is used to carry the device, such as a belt pouch.

Both protect and clean your mobile device
We came up with the idea when we noticed that touchscreen devices, such as digital cameras, iPhone, etc. become dirty quickly due to grease spots and finger prints on the touchscreen surface. Currently available bags and boxes only have limited support for cleaning mechanisms, e.g. a bag with microfiber lining. Such bags suffer from lack of stability and robustness of the outer shell and do not protect the device from physical damage. Therefore, our cleaning mechanism is targeted at boxes, such as belt pouches, which can be equipped with a hard shell that protects the device.

Scalr 1.1.0 – getting in touch – Part II

August 21st, 2009

As I promised in a further post I document here in my blog further steps and experiences in running Scalr on an own server infrastructure.

After Scalr was set up as described in my first post, some additional configurations have to be done to get in detailed touch with Scalr 1.1.0.
First log in as admin user to the Scalr frontend and create a new system user (“Client”) and activate it. After successful login with the new created and active user, you have to enter your AWS credentials and upload your public and private key from your AWS account.

The next screenshot show the configuration within my user.

Be aware to set this configuration right otherwise you will not be able to proceed.
