Intent,
executed.

Mintis is a non-invasive neural interface for people whose bodies no longer carry out what they mean. One deliberate signal in, one confirmed action out.

Fig. 1 Noise resolving into the mark
01 Platform

Three components. Deliberate input.

A headset reads the signal, a host application decodes it, and a reviewed registry runs the action. The input is deliberate gestures; the rest is built around them.

Headset

Worn, not implanted. It reads deliberate eye gestures, a triple blink or a left-right-left sweep. Each is a trigger: it fires, or it does not.

Host

Turns a gesture into a choice. An app on a phone, tablet or computer that decodes the signal. A carer puts everyday actions on a gesture; everything else is chosen by scanning.

Registry

Runs the action. Records it. A reviewed catalogue of actions: send a message, control a device, call someone. Every action is written to a record that belongs to the person.

02 Operation

From signal to confirmed action.

What using it is like, in four steps. Noise does nothing; only a deliberate gesture does.

Scan

Your choices come to you. The host highlights one option at a time, a well-worn accessibility model, and the actions you use most can sit on a gesture of their own. You never have to point.

Trigger

Make the gesture. A triple blink or a left-right-left sweep. A gesture people make without meaning to is never used, so a stray blink does nothing.

Confirm

Writes ask once. Deletes ask twice. The more an action can do, the more it asks: it is announced, and runs only when you repeat the gesture. Every ask times out to cancel, so no signal means nothing happens.

Execute

It runs once. One confirmation, one action, never two. If it fails, or cannot tell, you are told.

03 Characteristics

The switch, specified.

What the system is built to do, and how an input earns its place: recorded, replayed through the production decoder, and rejected if it fires on its own.

  1. 1

    Every candidate is recorded in labelled sessions, at rest and during natural reading, and replayed through the production detectors. A gesture that fires when nobody meant it to is never bound to an action.

  2. 2

    The plan said double blinks were rare. People blink twice about three times a minute while reading, so the measurement won and the gesture was dropped.

04 Registry

What one switch can reach.

Mintis does not write every action. A service describes its own interface, passes review, and joins the catalogue under the same confirmations as everything else.

  14. 14Let the carer inAsks twice

More reach, same confirmations. Questions answer at once. Changes ask first; a door asks twice. The people you choose can set it up, see what you let them see, and stop everything, and you can overrule them. Mintis is never the only way to call for help.

05 Position

Everyone else builds input.

Mintis builds the output layer and its safety model, and takes whatever input exists. That is why an eye signal is a legitimate first input, and why EEG changes the headset, not the platform.

Table 5 What Mintis is not

  • Not mind reading. It reads deliberate gestures, each made on purpose.
  • Not a brain-computer interface, yet. The proof of concept reads an eye signal.
  • Not CE-marked. Pre-market, no diagnostic or therapeutic claim.
  • Not a replacement for a communication aid. It runs beside it.
  • Not a data business. The record belongs to the person.
