# Interface Overview
Learn about the OCR interface components and how to use them for capturing and translating text from your game screen.
The OCR interface layout depends on the **output method** you selected when starting OCR:
* **Extra Window** - The interface shows the **Capture Area** and the **Side Toolbar** (right side)
* **Hyper Overlay** - The interface shows the **Overlay Toolbar** (left side), the **Capture Area**, and the **Side Toolbar** (right side)
## Capture Area
The Capture Area is a transparent overlay window that defines which part of your screen will be captured for OCR text recognition.
**How to Use:**
* Position the Capture Area over the dialogue text box in your game
* Resize the window to fully cover the text area
* Make sure the Capture Area includes only the text - avoid capturing UI buttons, character sprites, or background elements
* Once positioned, the Capture Area will automatically detect and capture text when **Auto Capture** is enabled
**Tips:**
* Leave a small margin around the text to ensure all characters are captured correctly
* Avoid capturing unnecessary parts of the screen, as this can reduce OCR accuracy

## Overlay Toolbar
{% hint style="info" %}
The Overlay Toolbar is only available when using **Hyper Overlay** as the output method. It will not appear when using Extra Window.
{% endhint %}
The Overlay Toolbar appears on the **left side** of the Capture Area and provides controls for managing how the translated text is displayed directly on your game screen.
#### **Hyper Overlay Toggle**
Turns Hyper Overlay on or off without stopping the OCR session.
#### **Text Styles**
* **Auto Text Size:** Automatically adjusts the text size to fit within the recognized text area
* **Auto Text Color (B/W):** Automatically sets the text color to black or white based on the background for better readability
* T**ext Size:** Manually sets the text size. Only available when **Auto Text Size** is disabled
* **Min. Text Size:** Sets the minimum text size limit when **Auto Text Size** is enabled
* **Max. Text Size:** Sets the maximum text size limit when **Auto Text Size** is enabled
* **Font:** Sets the font used for the displayed translation text
* **Text Color:** Manually sets the text color. Only available when **Auto Text Color** is disabled
#### **Background**
Controls the background displayed behind the translated text on screen.
* **None:** No background
* **Default:** Applies a blur effect and removes the original text from the background for a cleaner overlay
* **Solid:** Displays a solid color background behind the translated text. You can adjust the color and opacity
#### Text Segmention (N/A)
...
#### **Clear All Text**
Removes all translated text currently displayed on the Hyper Overlay.\
This does not stop OCR - it only clears the overlay text that is currently visible on screen.
***
## Side Toolbar
The Side Toolbar appears on the **right side** of the Capture Area and provides quick access to OCR controls and settings.
#### Capture
Manually triggers a screen capture and sends it to the OCR engine for text recognition.
* Hotkey: **Ctrl + Space** (default)
#### Smart Capture (right-click the Capture button to access settings)
Smart Capture adds intelligent detection before triggering OCR, helping to reduce unnecessary captures and improve accuracy.
* **Change Detection** - Only triggers a capture when the screen content has changed significantly:
* **Min. Threshold (%):** Minimum percentage of screen change required to trigger a capture
* **Max. Threshold (%):** Maximum percentage of screen change allowed before a capture is triggered
* **Stability Detection** - Waits until the screen content has been stable before triggering a capture:
* **Min. Stable Duration (ms):** Minimum time (in milliseconds) the screen must remain unchanged before a capture is triggered
* **Max. Wait Time (ms):** Maximum time (in milliseconds) to wait for the screen to stabilize before forcing a capture
#### Auto Capture
Automatically captures and processes text at regular intervals.
* Continuously monitors the Capture Area for new or changed text
* Hotkey: **Ctrl + Shift + A** (default)
#### Pre-processing
Opens image enhancement settings that are applied to the captured image before it is sent to the OCR engine.
* Adjust settings such as brightness, contrast, threshold, and filters
* Helps improve OCR accuracy, especially when using traditional OCR engines (Tesseract OCR, Windows OCR)
For more details, see [Pre-processing](https://docs.vntranslator.com/user-guide/ocr/pre-processing)
#### OCR Engine
Opens the OCR engine selection panel, allowing you to switch to a different OCR engine or language without restarting.
For a full list of available engines, see [OCR Engines](https://docs.vntranslator.com/user-guide/ocr/ocr-engines)
#### Capture Area / Screen Capture (Mouse Click-Through)
Toggles whether mouse clicks pass through the Capture Area window to the game beneath it.
* **ON** (default) - The Capture Area works normally and can be moved and resized using the mouse
* **OFF** - The Capture Area is locked in place and cannot be moved. Mouse clicks pass through to the game window, allowing you to interact with your game normally
#### Set Region
Allows you to redefine the Capture Area by drawing a new region directly on the screen.
* Hotkey: **Ctrl + Shift + R** (default)
***
## Status Bar
The Status Bar is displayed at the bottom of the Capture Area window and shows real-time information about the current OCR session.
**Information displayed:**
* Current Display Settings
* Capture Area Coordinates
* OCR Processing Status
