Neonode is the company, zForce is their scheme of using IR interruption for touch.

The original Nook Simple Touch exposed internal values from the driver as:
/sys/devices/platform/i2c_omap.2/i2c-adapter/i2c-2/2-0050/ledlevel
If I remember correctly, it actually used a TI MSP430 to do the scanning.

The Glow3 uses the NN1001 (main controller) and NN2003 (expander?) chips.
The Glow 3 had the driver here, but no usable values:
/sys/devices/platform/imx-i2c.1/i2c-1/1-0050

The values are useful as I had a little app to visualize the IR paths to help you determine where the cruft had collected in the bezel.
