Interaction Design: Tilde’s Web of Parameters

Image

Today, dr. ir. Tilde Bekker was telling me about interaction design, how several different parameters are connected to each other in something like an elastic web. If you change one aspect, it influences the others as well. Continue reading

How to make Origami Flowers

Just a bit of fun: since I mentioned “Origami Flower” once, the search term most used to find my blog is just that. I find it quite intriguing and can imagine that people who want to start making origami flowers, are not that interested in my university projects.

So here goes: a guide that tells you how to fold an Origami Flower. For those of you who do not speak Italian, you don’t really need the text. Just remember that a dotted line is a fold, when it’s irregular it folds towards you (like a mountain), if its a regular dotted line it folds away (like a valley).

Guide to folding a four-petal origami flower

Use paper that is different on both sides, like in the picture, for a nice effect. If you make a few and stick them on cocktail sticks, using masking tape or colored tape, you can make a bouquet!

Have fun… 😉

And if you are interested in my projects at Eindhoven Technical University, take a look around on my blog and see what I’m up to these days!

A Recap of Two User Evaluation Sessions

Finally, it’s here! A condensed video showing the most interesting outcomes of two User Evaluation sessions about the Light Scribing concept.

If you would play this video on your smartphone while Lightscribing, I am sure it would give a nice effect.


And why not program the phone to generate a random color sequence, like the screensaver this video was taken from?

Second User Evaluation of Light Scribing

One week after the first user evaluation, we held another evaluation session. One reason to do this was to see if the technique would still be interesting after some time, and if users would be prepared to keep using it.

All four students in this project were present, and some had prepared special hand-held lights to use. On top of that we had the use of a more advanced camera that could do longer shutter times. Three of the four original users were present as well.

The Crucial Factors applied to Light Scribing

In the next user evaluation, I would like to find out more about what values and meaning user describe to Light Scribing. But what are the best questions to ask? Using my own version of the Top 10 Needs for a Positive User Experience by Sheldon (2001), I will start to chalk up some possible questions to ask. Hopefully they give me some kind of framework to at least look at the whole experience from different angles. Continue reading

10 Crucial Factors of User Experience Design

From a presentation by dr. Jacques Terken, the Top 10 Needs for a Positive User Experience according to Sheldon (2001):

“Autonomy—independence Feeling like you are the cause of your own actions rather than feeling that external forces or pressure are the cause of your action

Competence—effectance Feeling that you are very capable and effective in your actions rather than feeling incompetent or ineffective

Relatedness—belongingness Feeling that you have regular intimate contact with people who care about you rather than feeling lonely and uncared for Continue reading

Experiencing Light Scribing

Some videos made during the User Research session I had with 4 teenagers aged between 12 and 18. I used the Co-Creating Stories technique as described by Derya Ozcelik.

Part 1: We watched a music video-like clip of teenagers hanging around, talking to friends, playing sports etc. Then we talk about our own experiences and this recording starts. Continue reading
