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 begin forming the shape of the outer case

  Step 8  Fold the longer edges of the outer case first

Step 8 Fold the longer edges of the outer case first

Step 9 Tape the longer flap down

Step 10 Make sure that the edges align nicely

Step 11 Now tape the flap close to the viewfinder down and leave the other flap open to insert the inner casing

Step 12 The outer case is ready

Step 13 Apply double-sided tape or glue to all the tabs on the cut card of the inner case

Step 14 Fold all engraved lines of the case, to begin forming the shape of the inner case

Step 15 Fold the area around the viewfinder circle so that the edge points to the inside of the casing

Step 16 Tape the longer edge of the casing down, make sure that the edges align

Step 17 Now fold the shorter edges of the inner casing

Step 18 Fold the flap of the viewfinder so that it aligns with the existing cut out of the view finder

Step 19 Tape the flaps down on to the side of the case

Step 20 Tape the flaps down on to the side of the case

Step 21 Leave the other side of the casing open to insert the electronics

 
 

Step 22 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 23 Slide the inner case into the outer case, align the camera and screen cutouts.

Step 24 Close the tap with glue or double-sided tape

Step 25 The TaskCam Long is ready to use
