Xen Sensor

A light ear clip that reads your heart rhythm and plugs straight into your computer. Ships today.

Clip it to your ear, plug it into a USB port, and the software stops guessing. It reads your heartbeat while the session runs, so what is on screen answers to you rather than running past you — the door opens because you settled, and the score afterwards is a measurement rather than an opinion.

In the box

• The Xen Sensor with its earclip and USB lead.
• The Grapher, free — watch your own heart rhythm in real time. $29.99 on its own.
• Setup instructions for Mac and PC.

Works with The Passage, Zen Quest and 49 Zen Masters, on Mac and PC. Already own an IomPE, Iom or Lightstone? You do not need a new sensor.
