User dialog
Messages or surveys can be manually or automatically displayed on the tracker’s display. Test persons respond by touch display, inputting text, or by recording their own audio comments.
Recording movement patterns
Traveled routes can be passively noted automatically or actively entered by the user.
Should the device be in an enclosed space or not have any GPS reception, a GSM multilateration process is used to alternatively identify locations based on the last known coordinates.
The results are standardized lists with time and geo-coordinates which can imported into a map and thus depicted as a route.
Photographic documentation and record
Test persons can take and comment on photographs of their immediate situation. Any photos are then automatically centrally stored with a time stamp for later analysis and documentation.
