Vision Browser in detail: Human Type — realistic typing emulation

Human Type — a feature for realistic text input that mimics human typing: with a natural rhythm, pauses, and varying keystroke speeds.

We’ve updated the Human Type feature in the Vision antidetect browser, and in this article, we’ll explain exactly what’s changed and how it improves bypassing anti-fraud systems.

Anti-fraud systems analyze not only the browser fingerprint but also on-site actions: typing speed, pauses between characters, and so on. If text is entered too quickly or always at the same speed, it may appear to be automated.

Human Type adds natural delays and varying typing speeds, so actions appear realistic and reduce the risk of additional checks or restrictions from anti-fraud systems.

Unlike standard text input, Human Type sends a genuine sequence of keyboard events: key presses and releases, character input, use of Shift, Backspace, and pauses.

In version 3.5.1, we've revamped the Human Type feature. Below are details on all the changes.

Previously, automatic typing could give itself away with pauses: each character appeared with nearly the same time interval because the delay between keystrokes was selected randomly within a small range.

This implementation, as well as its simpler version with absolutely uniform keystroke timing, is considered the industry standard and is used in most popular antidetect browsers.

Most anti-fraud systems on popular websites accept this approach, but advanced protection mechanisms could detect the artificial text input and result in bans.

Why this doesn’t work: typing speed varies from word to word and from key to key. The distance between keyboard keys also affects keystroke speed. For example, the average user will spend significantly less time typing the word “FAX” than the word “BOW,” even though both words consist of 3 letters.

The Vision development team has implemented a more advanced version of Human Type, based on the study of human typing patterns. Now, typing speeds vary — sometimes faster, sometimes slower — and adjacent keystrokes are linked by a rhythm that mimics that of a real user.

Human Type in Vision analyzes not only the characters themselves but also how a person typically types them on a keyboard: which hand, which finger, and where the keys are located.

For example:

• if letters are typed with different hands, the text is typed faster;

• if one hand or one finger is used consecutively, a slight delay occurs;

• keys on the main row are typed faster;

• fingers have to reach further for keys on the bottom or number row;

• characters typed with the Shift key are slightly slower due to the extra keystroke.

As a result, the typing appears natural and mimics the behavior of a real person.

Human Type now adds small pauses in places where a person typically pauses while typing:

• after a space, before starting a new word;

• before commas, periods, question marks, or exclamation points;

• in long sentences, as if the person paused for a moment.

Because of this, the typing looks more natural and doesn’t resemble machine-generated text.

People type certain characters faster because these combinations are common in the language or are easy to type on the keyboard. Human Type takes this into account for Russian and English text.

Now, common combinations are typed faster than rare or awkward ones. As a result, the typing looks more natural, especially in long texts — as if a real person is typing, rather than a program with random delays.

Human Type mimics not only typing speed but also the actual key presses, taking into account:

• the moment the key is pressed;

• the appearance of the character on the screen;

• the release of the key.

Even the key hold time varies slightly depending on the character and the key’s position on the keyboard.

People sometimes make mistakes while typing, so Human Type can mimic this behavior as well. The feature may accidentally press a neighboring key, then quickly correct the error using Backspace and enter the correct character.

These typos look realistic: the system specifically selects neighboring keys on a QWERTY keyboard because, in real life, people are more likely to miss the nearest keys rather than press random letters.

Typos are added carefully and only in situations where they look natural:

• in sufficiently long text;

• not at the end of a line;

• where a realistic adjacent key can be selected;

• taking into account the text’s case and language.

Human Type has been moved up in the architecture: from the so-called Blink layer to the browser/content layer. This brings the feature closer to true system-level input: events are sent to the active browser widget via the standard keyboard event mechanism.

Human Type is no longer an internal text insertion feature but a full-fledged keyboard emulation at the browser level.

All Human Type improvements work with both English and Russian text. The feature understands the Russian keyboard layout, knows the placement of Cyrillic characters on the keyboard, and accounts for common letter combinations in the language.

This is important for users who use the Vision antidetect browser not only on English-language websites.

We have redesigned Human Type to ensure that text input appears as natural as possible not only to the user but also to anti-fraud systems.

The feature now takes into account typing rhythm, key layout, finger movements, natural pauses, occasional typos, and full browser keyboard events.

We generally do not recommend drawing conclusions based on the results of any checkers and insist on testing any functionality in real-world usage conditions. However, in the case of our ultimate implementation of Human Type, any available comparison with other antidetect browsers leaves them far behind.
