2.2 Haptic design
The Zeitgeist 2 is rectangular, slightly oval in shape, with a smooth casing of black
plastic. It measures around 4 x 7 centimeters in size and is one centimeter thick.
On the top right of the device there is a slightly raised loop for the neck strap, and three
metal buttons can be found on the right-hand side.
The underside of the device has a USB-C port for inserting the charging cable.
On the rear you will feel four screw holes and a slight depression for the rating plate,
while on the left-hand side the casing is closed.
On the front is the display, with the speaker underneath, as well as the microphone
under a grille-like structure.
Within this you can just feel the optical sensor for the Lumitest on the left-hand side, and
on the right an LED (light-emitting diode), which lights up in different colors to indicate
specific operating states: (red and green for charging, and blue for the microphone). For
further details see the relevant sections.
