Three ProbeTools are currently available:  TaskCam, VisionCam and Automatic Interviewer

TaskCams recreate the proven Cultural Probe technique of relabelling disposable cameras with requests for pictures. They have a small screen on the back that shows a scrollable list of requests for pictures.

The 3D Printed TaskCam can be printed on most 3D printers, and is robust and flexible enough to use across multiple studies.

The TaskCam Paper Long is the simplest of all TaskCam enclosures. It uses the TaskCam Arduino Shield straight out of the box without any modifications. It is very easy to make and has plenty of free space for additional graphics. The casing is constructed from two A4 sheets of card or paper, cut out according to the template we provide.


This right-handed Paper TaskCam is easy to make as it is constructed from two A4 sheets of card or paper.

The left-handed Paper TaskCam is easy to make as it is constructed from two A4 sheets of card or paper. The configuration for left-handed users is unique for a camera, let alone a ProbeTool.

VisionCam offers the chance to capture long-term recordings of settings without invading privacy. Based on a Raspberry Pi , it uses computer vision to trigger and manipulate images, producing stop-action recordings similar to line-drawn animations.

Compact VisionCam is the easiest version to construct and the case can be produced on most 3D printers.  Its asymmetrical form is the result of using the Raspberry Pi and display screen 'hat' in a completely standard configuration.

VisionCam Tall repackages the display screen 'hat' by means of a custom PCB to produce a symmetrical housing. The case is easy to make on most 3D printers.


VisionCam Accessories are a selection of 3D printable parts for VisionCams that can be added to extend their physical functionality. Designed to be attached by using strong elastic bands, they can be printed on most 3D printers.


Automatic Interviewer is an audio device that uses speech generation to read questions from a text file provided by researchers, then records users’ replies for up to about 30 seconds.


The Automatic Interviewer is currently in development. We expect to release it later this year.
