Third User Evaluation

Experiencing the interactive wireframe prototype of the LightScribe App.

QR-Code Icing on a GUI cake

Just as a nice extra, I made some QR codes to get to the LightScribe interactive GUI pdf:

and to the LightScribe blog:

Let’s test this…

Yes, they work! Tip for a handy free QR scanner: the aptly named Barcodes Scanner app. Have fun!

Looking for something else, I found this useful little website. I can’t use it for my automatic photo blog because the output is an email (and that takes too long for me), but it seems useful for monitoring websites that don’t have email subscription or RSS.

Schematic Overview of GUI

Interactive GUI

Download the interactive graphical user interface (GUI). Interactive PDF. *New and improved!*

Although it is nice to see how the app works visually, you can also check out this overview, where the interaction is drawn out in a schematic.

User Evaluation Serendipity

A nice bit of unofficial user research just thrown into my lap. A few days ago, I created an automatic photo blog to store the pictures from the LightScribe App prototype. I put a few existing pictures on it to test the setup. I was very surprised when it started raining ‘likes’! Hint: go to the bottom of the post and click on the star 🙂

At first it was just nice to feel appreciated, but then I decided to check out which picture had the most likes. And it turned out to be exactly the one I had already chosen to be the basis of my GUI design! So have a look and see if you agree.

Slow Shutter Cam

Today I found this great app: Slow Shutter Cam for iPhone. What I like is that although the functionality is quite simple (you can adjust the shutter time), it has positive reviews and people are also using it for light painting.

Good to see that apparently there is a need for this kind of app!

A LightScribe Story

Imagine you are a 15-year-old boy and bored to no end. Finally, the school bell rings and you are done for the day. Usually, you would hang out in the nearby park with friends, doing nothing really. But ever since some of your friends introduced you to it, you are often using the LightScribe app, like today. When you see your friends, you all whip out your smartphones and start the app. The app sees all available LightScribers in a nearby radius, so you can easily select your friends’ group from the list. With some laughs and jokes, the best location is picked. Perhaps when it gets darker outside, you will move to the park, but for now, the decision falls to the bike shed.

The app picks one random cell to be the ‘photographer’. The other participating smartphones are designated ‘light sources’. You are picked to be one of the light sources, and the screen of your cell

Arduino Code Setup

This is a first draft of the structure of the code for my project. ‘Void’ and ‘Loop’ are places in the code, so I know what to put them under once I start writing.

The blue bits are different interactions I could write. The first is that when the light sources move closer together, they take on light properties from each other. This would hopefully encourage users to move around more, thereby increasing the exercise effect. Also it makes the interaction more interesting the more players you play it with.

Other interactions could take place at the same time or instead of this one, perhaps I can come up with some more!
