TaskCams recreate the proven Cultural Probe technique of relabelling disposable cameras with requests for pictures. The TaskCam Long is the simplest of all TaskCam enclosures as uses the TaskCam Arduino Shield in an unmodified, straight out of the box state. It is very easy to make and has plenty of free space for additional graphics.
The TaskCam Long has a small screen on the back that shows a scrollable list of requests for pictures. Researchers can load their own list of requests onto the camera to prepare for a study. When users take a picture, the image is tagged with the current request, and stored on a standard flash drive that can be removed for downloading.
The casing for the Paper TaskCam is constructed from two A4 sheets of card or paper, cut out according to the template we provide. The device requires a custom Arduino shield, buy online at cost price, or follow the open-source plans to make yourself. Smart power management means that two AA batteries provide more than enough power for an entire user study.

Step 3 Your camera needs some questions. For advice on how to write good Probe questions, please read here. Insert the micro SD card into your computer. Write your questions in the text box below, giving each question a new line. Once you're done, click "Download questions file". Your browser will download a file called "q.txt". Place that file into the SD card. Eject it and unplug it from your computer.
Please note: if you have downloaded the file before your file might be called q(1).txt and needs to be changed.
