RFID Sensor

This is the perfect accessory for synchronous recording of biosignal data and ID-mappable events. Usage examples include token detection and reaction time analysis in object manipulation tasks, and also differentiated event annotation.

Example 1: For manual event annotation, it is an improvement to our handheld push button. The push button only provides an on/off behaviour, while with the RFID accessory you can have different tags associated with different events (e.g. starting of the test, stopping the test, presentation of a given stimuli), and more easily encode such events in a channel synchronised with the remaining biosignal data.

Example 2: In ergonomics (e.g. factory floor), the reader can be fitted to a glove (on the back of hand) and used to detect tools that the user grabs (the tools need to have a tag on them). The accessory is connected to the hub in the same way as the remaining sensors used to monitor the user (e.g. EMG, accelerometers, etc.).

Example 3: Track people while roaming around a physical space; using biosignalsplux with biosignal sensors and the RFID accessory (which the person carries together with the other sensors), different sections of the house can have an RFID tag, and whenever a person enters a given section the RFID accessory is used to scan the tag; as a result it is then possible to analyse the physiological responses of the user in each section of the house.

Example 4: Evaluate reaction time together with physiological data in psychophysiology studies… the subject is sitting down, connected to the standard sensors and the reader is connected to the hub and placed on a table. A computer provides cues of objects that the person needs to place on the reader and each object is fitted with a tag, allowing then to detect when the person completes the task.
