Current setup

Our current setup consists of the following three kits (see Figure 3 for the system diagram):

User's kit. The user-worn part (Figure 2) includes the following:

Moderator's kit. The environmental camera setup consists of the following:

Alternatively, a moderator-carried camera (a Sony DCR-TRV30E PAL mini-DV digital handycam, equipped with a VCL-ES06 x0.6 wide-angle lens) can be used. In addition, we have previously explored the option of hiding the moderator-controlled camera in a cell phone shell to make it less visible in public places (Figure 4).

Figure 4. One of the earlier setups had the moderator-controlled camera built in a fake shell of a mobile phone. The wire goes through the sleeve to a recorder on the waist. This solution allows for quiet, non-visible recording in public places.

Maintenance kit. The following are tools for running and preparing the tests and maintaining the setup.

The kits fit into two aluminum briefcases that can be carried to the site of experiment (Figure 5). The total worth of the current setup, including labor and component costs, is about 10,000.

Figure 5. The whole kit fits into two aluminum cases that can be taken to the site of study. This case includes environmental cameras; the other kit contains the user-worn components.
