Let me introduce myself

Nils Dekker

Interaction Designer To-Be

Hi, my name is Nils Dekker, I am 25 years old and studying to become an Interaction Designer. I am very energetic and well-ordered. To regulate my energy, playing Handball at a European level does some good compensating and thought me what it takes to work as a team. I like to think of myself as honest, trustworthy and people can always depend on me. Besides school, work and sports, I love to travel the world with some of my dearest friends.


These are the most interesting, time consuming or fun projects I have worked on 🤟🏼

Les Recepten

Educationalists are currently having more burn-outs (22.1 percent in 2017) than other employees in any other profession (15.9 percent) in the Netherlands. The percentage of educational staff in primary education experiencing this high level of work pressure increased from 39.5% to 59.8% over ten years. One of the main causes is the growing number of tasks that teachers are assigned with atop of their regular responsibilities, leading to poor education.

“How can an interactive product ensure that primary school teachers (25 – 35 years old) with a high stress level (8 or higher on a scale of 1 to 10), remain positive and capable of preparing the class of the following day after an acute planning change, resulting in a stress level of 6 by the end of the current school year?”.

Les Recepten is an online teaching assistant named Robin which provides the teacher with a clear scheduled working day based on the current progress. Making adjustments is possible via voice or chat with Robin. Since the App recognises which method from which publisher is used, it is able to anticipate  the amount of time available for lectures in the upcoming workdays in the teachers’ calendar.
This will put the focus back on teaching instead of the peripheral issues. The application works together with the largest publishers, ensuring that no teacher feels left out.

Mockup Lesrecepten


Amsterdam is a very crowded city with a dangerous infrastructure. One of the locations where the congregation of cars, bicycles and pedestrians is especialy dangerous, is the Wibautstraat. Lots of pedestrians walk through a red traffic light. In this kind of streets, it is of extreme importance that pedestrians cross the street safely and avoid collisions. Most pedestrians walk through the red traffic light because they are in a hurry or do not see any cars coming. In the end, nobody likes waiting. So, in case the coast seems clear and there is no indication of the remaining waiting time, chances are high that a pedestrian will cross the street. But what if we could change this.

We introduce OpgeLED. OpgeLED adds a special traffic light to the zebra crossing for pedestrians which displays the remaining crossing and waiting time. Due to the clarification of time, the pedestrians might consider waiting for the red traffic light to turn green.

The pedestrian walks up to the crossing and activates the ticking noise we are used to by pressing the crossing button. This way the user knows that the crossing recognises his presence. Besides the traffic light and waiting timer the most important aspect of OpgeLED is the interactive wait time bar which can be seen on the zebra crossing. With our expectations of OpgeLED we could realise a decreasing number of red traffic light crossers in the Wibautstraat.


Lead Design Internship 

The position I fulfilled for Dit Is Wijs was Lead Designer for the intranet named Metis 2.0. My main focus was the interaction aspect. My responsibilities within the company included communication and consultation on intranet changes, joining and organizing meetings twice a week at the head office in Rotterdam with different departments to discuss the progress of Metis 2.0 and working on the development of intranet designs in the Hoofddorp office twice a week. The communication channels I used while working for Dit Is Wijs were phone, e-mail, Slack, Zeplin and Discord.

I applied my knowledge of design theories and methods to create the best possible user experience for the customer. Since all departments needed their own specific data, had their own way of processing it in combination with the different relationships between departments, this was quite a challenge I was excited to take on. After some iterations on my designs the departments and I agreed on the final designs. I communicated the final designs throughout discord with the development team in Columbia. This never succeeds within the first try but after some back and forth negotiating, we delivered some very practical designs which all departments felt really comfortable working with and were genuinely implemented. 

Usability Testing Hva Libarary

For this project the main focus was improving the usability and user experience of the current digital library of the Hoge school van Amsterdam (HvA). Users were having trouble figuring out how to properly use the website and all of its functions.
The main problem was experienced on the home page, when entering a search request and when applying filters. The experience was so unpleasant that it frustrated its users leading to them giving up on their search.

“It’s quite a task to get good information and if you first have to read a manual to be able to use the system completely and correctly, it is heavily demotivating.”

– Joost Spijkers (22)

I conclude that all searching possibilities are present on the site. In comparison with other databases, it transcends itself by the ability to extract from multiple databases gather information in one place. Which simultaneously forms the problem. Since it has all the functionalities and filter types in one place, it has become a mess with difficult terminology. 

My proposed solution includes the creation of a clear structure with inclusion of the possibilities and elements that the current HvA library site possesses. Moreover, adjusted and user-friendly terminology will be used in order to convey this as clearly as possible to the target group.

Ubiquitous Computing

During this project I was expected to improve a user experience by solving a problem with an Internet of Things (IoT) application. The sensors (input) and actuators (output) were encoded in Arduino.


In case my handball teammates and I want a cold beer after our game, I always bring a small beer box consisting of 6 beers with me. My teammates are aware of this and without asking for permission they always take beer from it. So, sometimes I miss out on my own cold treat because my dear teammates already finished them when I was in the shower or during stretching.


With some actuators and sensors this problem can be solved easily. When there is beer in the box the button on the bottom is automatically pressed which turns the system on. The light sensor measures if the lid opens and in which case the LED’s will light up, the vibrator will vibrate and the Piezzo buzzer will give an annoying sound. This will warn me that one of my teammates is trying to steal a beer and will allow me to prevent the problem from happening. Moreover, my beer box only cooled for around 4 hours after which, the beer gets warm which is a waste. So, after the cold beer placed in the box in and the button is pressed for the first time, a timer starts running. After 4 hours the box will clearly indicate with a green light and a happy tone that the beer can be taken by anyone.
