TaskCam Paper

Right-handed Version

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 12 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 13  Insert the SD card into the SD card holder on the camera module

Step 13 Insert the SD card into the SD card holder on the camera module

Step 14 Apply double-sided tape or glue to all the tabs on the cut card of the outer case

Step 15 Fold all engraved lines of the case, to beginning forming the shape of the outer case

Step 16 Progressively begin to stick tabs in place as shown in the following sequence of photographs

Step 17 Tape down the edge of this tab fully to allow the inner case to smoothly slide inside the outer case

Step 18 Stick the last tab in place, taking care to leave the flap shown at the bottom of this photo open, as this is the door to slide in the inner case later

Step 19 Apply double-sided tape or glue to all the tabs on the cut card of the inner case

Step 20 Fold all engraved lines of the case, to beginning forming the shape of the inner case

Step 21 Progressively begin to stick tabs in place as shown in the following sequence of photographs

Step 22 Place the camera electronics in the inner case as shown, and close the flaps

Step 23 Take the fully assembled inner case and slide into the outer case as shown in the following sequence of photographs, not forgetting to fold and insert the viewfinder

Step 24 The TaskCam paper is ready to use
