Tobii Glasses Eye Tracker
Charging the IR Markers
Included in the package is one or more (depending on package) IR Marker Chargers that can each charge up to 10
IR Markers at a time. When more than 1 charger is supplied the package will include a splitter to split the power of a
single adapter over three different power outputs, one for each supplied charger.

To place an IR Marker in the charger:
1. Connect the power adapter to the charger. The charger’s Power LED indicator should turn green.
2. Hold the marker with the IR Marker front facing upwards.
3. With the connection points towards the center of the charger, insert the IR Marker in a free slot.
4. Press the IR Marker firmly into place, it should snap in its holder.
5. The LED indicator of the IR Marker will turn blue, indicating that it started charging. Remove and firmly
reinsert any IR Markers that don’t connect, e.g. when the LED does not light up.
6. The IR marker is fully charged when the LED indicator turns green. Read about the LED indicator on the next
page.
IR Markers
To remove an IR Marker from the charger, tilt it outwards and pull it up, this is similar to removal from an IR Marker
Holder.
Battery life of IR Markers
The battery life of the IR Markers is dependent on usage. When a pair of Tobii Glasses (turned on) is detected IR
Markers will be activated. IR Markers never turn off but instead go into a standby mode, both while in and out of a
Holder. If stored or not being activated by a pair of Tobii Glasses that are in range, their battery will last for about 14
days. It is recommended to keep the markers charged in a powered IR Marker charger until starting a test. Always
check if the battery status is still sufficient before using them again after a few days.
Battery life of the IR Markers when constantly activated by a pair of Tobii Glasses is approximately 4 hours. However,
in most cases the duration will be longer since the markers will preserve battery power by switching to standby mode
whenever the glasses are out of range.
Charging the IR Marker completely can take up to 7 hours. Depending on the residual charge in the IR Marker this
may require considerably less time. An empty IR Marker will charge from 0% to 50% in about 1.5 hours. To reach a
100% charge, it will take an additional 5-6 hours of charging.
