Predictive Analysis Interface

A suprisingly old yet still expensive and complicated cybernetic enhancement or synthetic addon. Allows seeming precognition, though limited.

Utility

A PAI system consists of a central processor, mounted in the skull, connected to the brain's sensory areas, and a grid of scanners and detectors, mainly short-range laser radar and electromagnetic pulse detectors. Those sensors monitor the area around the user, and inform the user whenever they detect something threatening. Like a sixth sense well, technically humans have tens of senses, but still., they feel those signals and can react accordingly.
Those signals are most often the electromagnetic signatures a coilgun gives off before it fires. This applies to railguns and Plasma weapons as well. The radar is there to detect weapons that do not produce the signature, like missiles or conventional weapons.
Of course, the system only informs the user of these threats, it's up to the user and their reflexes to actually avoid getting hit, be that via dodging or blocking, often with a sword, shield, or some special armour plating. That's also part of why they're only given to higher-up people, as those people tend to have better training and sharper senses.
There's a variant that considers melee combat, predicting sword swing trajectories and such. These are a lot more complex and expensive, and are thus quite uncommon.

Access & Availability

Despite being available all over human space, having been invented in the 2200s, the tech is very expensive and often reserved for high-ranking personnel or spec ops units. The actual machinery has remained roughly the same for over 500 years, as while it is complex, it's reached a sort of peak.

Complexity

The central component of a set of PAI augments is a processing chip. That chip handles the inputs from the sensors and tells the brain where they're coming from and how fast, and where. It connects to the brain via standard connections, which connect to parts of the brain that handle senses. On the outside, the sensors are a grid of magnetic pulse detectors and radars, mounted on the user's helmet and/or a specific crown-style design on their head. The entire set is still somewhat complex to make, even despite being over half a millenium-old technology.
