The Personal Efficiency Trainer
PET GSR Recorder, Wireless GSR, Computerized Biofeedback System
INTRODUCTION
A central concept to our product line is the Personal Efficiency Trainer (PET). The PET records physiological activity simultaneous with audio and/or video and these data can be reviewed both in real time (feedback) and offline. For offline analysis we have developed highly flexible and easy to use software.
The PET is developed for a variety of uses.
 The PET GSR RECORDER can be used as a stand alone - ambulant - psychophysiogical assessment device. Since the PET is capable of recording physiological activity simultaneous with audio (and video) it is possible to gain environmental information of what happened during the recording. In this way it is possible to perform whole day recordings and assess, for example, which events during a day are experienced as most stressful (e.g. specific social interactions, specific topics). This type of assessment can be helpful in a variety of (clinical) situations, e.g. treatment of phobia's, depression, anxiety and sports psychology.
The PET can also be used as a stand-alone feedback device. The PET is equipped with auditory and visual feedback. The assessed parameter can be directly fed back to the user in order to gain more control over this measure (e.g. self-regulation or GSR-feedback for relaxation or desensitization). Furthermore, by the embedded alarm functionality, the PET can also be programmed by a therapist to alarm users when they should perform their feedback sessions. The data from feedback session can automatically be saved in the PET, for later review and reporting by therapists.
The basic version of the PET is delivered as a GSR (Galvanic Skin Response) recorder device, capable of measuring the relative stress response, which is a well established measure for arousal and stress. The PET GSR RECORDER records this activity simultaneous with audio and/or video and can be reviewed off-line. Furthermore, the PET offers standalone GSR feedback for stress reduction training or stress and vigilance monitoring. The PET can also give an absolute indication of the GSR level in MOhms.
There is also a revolutionary new, easy-to-use and affordable way to measure high-quality EEG signals wirelessly. The EEG interface consists of a headband which can be worn over the head. There is no need to prepare or abrade the skin before recording EEG. The (disposable) sensors are snapped on to the head band, and the EEG signals are sent to a receiver device wirelessly.
Our EEG unit can interface in two ways. Firstly, it can interface directly with our PET and provide - stand alone - (neuro-) feedback or record the EEG data synchronous with other physiological measures and audio (or optionally video). Secondly, the EEG unit can also be delivered with a PC . In this way (neuro-) feedback or recording/storage of the EEG data takes place in the PC. If required, the EEG unit can also interface by USB instead of wireless.
Several software packages (PC software and PET embedded software) will become available for different purposes, e.g. additional EEG analysis software, memory/attention training, clinical protocols (ADHD, Depression) etc.

SOFTWARE
The PET will be delivered with PC software. New feedback protocols, patches, functionality etc. can be added to the PET in this manner.
In the screenshot below (PC Monitor not included with the PET GSR RECORDER) one can see a screen shot of the PET software with a 7,5 hr. segment of GSR. In the following we will explain the software using GSR, but everything with respect to GSR also accounts for EEG (filtered or unfiltered) or any other physiological signal.
The software is very intuitive and offers high flexibility for reviewing the data saved in the PET. The bottom graph always shows the whole session recorded. This can be a 1hr. recording during a therapeutic session, but this can also be a 24 hr. recording for evaluating someone's experienced stress levels during a day. In the section in the right top one can see a zoomed section of GSR activity. By clicking or selecting a section in the bottom graph, one will see that section zoomed in the right top corner.
The data can also be played back. Especially if audio is recorded with the data. One could double click on a specific section (say, just before a big peak, in order to find out what triggered that response) in the bottom graph and then the data is played back from that point, with simultaneous audio playback and the actual GSR levels depicted in the right top.
With the software one can also program alarms, by which the user of the PET can be triggered on specific times/dates.
