TaskCam Long

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 1 Cut the card for the camera case and gather components

  Step 2  Program the Arduino Uno following instructions  here

Step 2 Program the Arduino Uno following instructions here

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.

Step 4 Insert Arduino Uno into the main board

Step 5 Insert two AA batteries

  Step 6  Insert the Micro SD Card

Step 6 Insert the Micro SD Card

Step 6 Apply double-sided tape or glue to all the tabs on the cut card of the outer case

Step 7 Fold all engraved lines of the case, to beginning forming the shape of the outer case

Step 8 Progressively begin to stick tabs in place as shown in the sequence of photographs. The tab on the right side in this picture needs to stay open to insert the inner case later on.

Step 9 Apply double-sided tape or glue to all the tabs on the cut card of the inner case

  Step 10  Fold all engraved lines of the case, to beginning forming the shape of the inner case

Step 10 Fold all engraved lines of the case, to beginning forming the shape of the inner case

Step 11 First fold and tape the long edge of the inner case. Then prepare the folding lines of the lense and viewfinder

 
 

Step 12 Stick the three tabs in place around the viewfinder

Step 13 Insert the assembled working TaskCam Arduino Shield into the inner case. The screen should point towards the rectangular cut out for the screen. The camera should point out through the camera hole.

Step 14 Slide the inner case into the outer case, align the camera and screen cutouts.

Step 15 Close the tap with glue or double-sided tape

Step 16 The TaskCam Long is ready to use
