Procurios http://www.procurios.nl/ procurios_logo.gif Procurios is a young webdevelopment company based in Wijk bij Duurstede. In order to efficiently create networks and websites for its customers, it has built an elaborate framework. This framework contains modules for CMS, CRM, Webshopping, and others. My task is to extend and improve these modules and to keep the company sharp by monitoring the possibilities of modern technology and focus on the demands of the market.

The company develops, among others, games, theme park attractions, real estate visualisations, scientific simulations and educational tools.

]]> De Nederlandse Rijsimulator http://www.rijsimulatie.nl/ rijsim.jpg The driving simulator contains three screens: front, left and right. The student is surrounded by virtual reality and all car controls are available to him or her. My first task was to create autonomous car driving agents that behave naturally in any traffic situation. They keep distance, take several types of intersections, overtake each other, and pull in and out on the highway. I worked together closely with my colleague Robert den Holder who created the traffic model.

Next, I designed and implementated the virtual driving instructor, an adaptive, real-time, Intelligent Tutoring System that shows students how to drive a car. This virtual agent is a procedure trainer that guides the student step by step through a driving task. It checks if the student does the right thing and gives feedback if he/she doesn't. As the student progresses in skill, the amount of guidance for the task is reduced automatically (adaptive). The agent teaches the student how to control the vehicle (drive away, shift gears, brake, steer, etc), take intersections and roundabouts, and drive on the highway, taking exit and entry lanes. It keeps track of the performance of the student and adapts its instruction. In a tight schedule I analyzed the requirements, made a functional and technical design, created a new architecture, implemented the instructor together with Robert, expanded, tested (everyone tested), and debugged the system. The agent is based on didactic principles that were taught to me by the CEO of Green Dino, Jorrit Kuipers, and which I learned from books. It also integrates standards like Rijprocedure B, Het Nieuwe Rijden (Eco Driving) and RIS (Rijden In Stappen). It is unique in the world.

Olaf Achthoven and I set up an information management system GUI to manage students and lessons. It uses an MS Access database and is based on a workflow structure which is easy to learn and use.

I wrote the 50 page user manual for the driving simulator, to be used by driving school personnel.

Over 40 driving simulators have been sold, and the company is now market leader in the Netherlands.

I worked at Vizzavi as a contractor via the recruitment agency Computer Futures.

After half a year I felt there was a surplus of employees at the company. I was assigned a bugfixing job, which I performed for three more months and then I said goodbye.

The company, which had portals in several European countries, was eventually terminated by Vodaphone, because it was not expected to ever become profitable.

The program had to be used both as a stand-alone application and as a client-server application, whereby the client took the form of an applet (accessable via a Java plug-in) on the major browsers.

Using Java3D to create a Look and Feel that could be used to visualize Java's Swing framework was my idea. I saw this as a challenge and that was exactly what it proved to be.

I first worked at the estate Soeria (Laag Soeren) where I worked to finance an important meditation course. The jobs I did included cooking, dishwashing, purchase, and cleaning.

Later I was allowed to be transferred to the movement's headquarters (located with Purusha, in Vlodrop), where we had some opportunities to see Maharishi Mahesh Yogi in person. My activities there included administration, cooking, and cleaning.

After some time I felt there was no direction in my life or in the movement, and I had a strong urge to pick up programming again. So I left, leaving many good friends.
