TaskCams recreate the proven Cultural Probe technique of relabelling disposable cameras with requests for pictures. The 3D Printed TaskCam is the basic workhorse of the collection, robust and flexible enough to use across multiple studies.
The 3D Printed 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 3D Printed TaskCam can be printed successfully without support materials even on low-end printers. The device requires a custom Arduino shield, buy online at cost price, or follow the open-source plans to make yourself. Smart power management mean that two AA batteries provide more than enough power for an entire user study.

Step 9 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.
Step 12 Insert Arduino Uno into the main board, taking care to pass the camera lead between the two
Step 15 Slide the camera module into the the lower shell of the case, taking care with the camera and battery leads
