Networked Communications

The first example we see is the sub-etha Sens-O-Matic. This device is used along with the signaling device to alert hitchhikers about nearby spacecrafts. The sub-etha signal is a faster-than-light communication network widely used throughout the universe.

Similar to the Sens-O-Matic device this device, also referred to as the "electronic thumb," is worn as a ring by Ford throughout the movie which allows hitchhikers to flag down passing spacecraft to hitch a lift (1).

In order to communicate between the spaceships, video calls are made between the spacecraft (2).

When pointed at a person and the trigger is pulled, the target automatically sees things from your point of view. This is arguably networked communication because the target can see your perspective through technology.
