TaskCams recreate the proven Cultural Probe technique of relabelling disposable cameras with requests for pictures. The Paper TaskCam is housed in a casing made from paper or light card, allowing it to appear as playful or elegant as required. TaskCam Paper is available in both left and right-handed configurations.
The Paper TaskCam 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 14 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.
