Dot Pad 320 Appearance

When the Dot Pad 320 is removed from the box and placed on the desk, the square body is slightly inclined towards the side of the body and is in the correct position. The side closer to the body (the lower slope) is the front, and the farthest side from the body (the highest side) is the rear. The main areas that control the devices in the Dot Pad 320 and output braille are located on the top right sides, on the left side, and on the bottom plane. Therefore, this manual provides guidance on the top and right sides, the left side, and the bottom surface controls.

1. Dot Pad 320 Top view****

   • When the Dot Pad 320 is normally placed, the upper surface of the Dot Pad 320 is divided into the following parts from nearest to farthest from the body:

   • Braille text display area.

   • The keyboard area where the panning and function keys are gathered.

   • The graphic area where the tactile graphic is displayed.

   • The Braille text display area serves as the braille output of a typical braille information terminal; it consists of 20 cells in a long horizontally rectangular frame, arranged at standard braille spacing. Thus, 20 alphabetic characters can be represented at the same time.

   • Starting from the left to the right, the keyboard area consists of the previous panning key, keys F1 through F4, and the next panning key. The shape of the panning keys is a triangle, which distinguishes them from other Function keys which are in an oval shape.
     Note: A panning key is a key that moves to the previous and next line along the braille cells.

   • The Function key can be used to connect with the voiceover. The key operation method is as follows (description in the brackets are the actions taken on your device to achieve the same results):

   • F1: Moves from the currently focused object to the previous one. (Swipe one finger to the left)

   • F2: Go to Home.

   • F3: Executes the currently focused object. (Double-tap with one finger)

   • F4: Moves from the currently focused object to the next object. (One finger right swipe)

   • The rightmost part of the keyboard area is the LED area.

Basic Functions
This section walks you through how to check the braille cell status of a Dot Pad 320 before you connect it to your iPhone or iPad, and the different vibration patterns that you can use to check the status of your Dot Pad 320.

Checking the Dot Pad 320 Cell Operation
The Dot Pad 320 verify the normal operation of the braille cells lowering all cells. The function and detailed operation methods is as follows:
Lower All Cells: Sometimes a previously displayed cell may not be able to go down, for example, if the Dot Pad 320 suddenly loses power. When you turn it back on, and then run Down All Cells, both the braille cells and the graphic cells that were up go down. To perform this function, press the previous panning key and the next panning key at the same time and then release them. All the cells that were up are reset downwards.

Understanding device information through Dot Pad 320 vibration signals.
Because the Dot Pad 320 does not have a separate external speaker, it displays the device’s operating status through a vibration pattern. The vibration pattern informs the user of information such as battery status, Bluetooth connection, power on, etc. Details are shown below:

• Power on: A long vibration occurs once when the power switch is pushed towards the back.
• Power Connection: If the power cable is connected normally, it will vibrate to indicate the current battery level.
• Battery Status Indication: Displays the remaining battery level through vibration between 1 and 5 times. For more information, see section 2.3 “Check the battery level”.
• Bluetooth connection successful: Two long vibrations will sound.

Checking the battery level
To check the battery level of the braille graphic information device, you can press and hold the previous and next panning keys at the same time for at least 1.5 seconds while powered on, and then release them. The levels for displaying the remaining battery are divided into 5 levels and are notified by vibration feedback. Each pattern is shown below:

• Vibration #5: The battery is at least 80%.
• Vibration #4 : The battery level remains between 60% and 80%.
• Vibration #3 : The battery level remains between 40% and 60%.
• Vibration #2: The battery level remains between 20% and 40%.
• Vibration #1: The battery level is less than 20%. Be sure to use it after connecting it to a power source.

Connecting Phone/iPad with Dot Pad 320 to Read Braille and Tactile Images

The Dot Pad 320 can display braille text and graphics. Braille text is displayed in the area of braille cells close to the front, and the graphic appears in the graphics area that occupies the largest area. This section walks you through Voiceover to view basic braille and graphic information.

Reading Braille Text
The way you read braille text is the same as how you use other braille displays. Voiceover displays what it outputs as speech, through text and its dedicated symbols; if you can’t display all the text at once, use the previous and next panning keys to move the lines to read the following braille text.

Displaying the Image (Default)
When Voiceover determines that a particular object has image information on the screen, it immediately outputs the image information of the currently focused object to the Dot Pad 320, which you can use as follows:

• Move to the home screen with the Dot Pad 320 connected.
• Focus on any application on the home screen.
• The appearance of the application icon appears in the graphic area of the Dot Pad 320.
• In the braille area, what Voiceover outputs to speech is simultaneously displayed in braille text.

Reading images in detail with rotors

1. Adding Image Navigation Options to the Rotor
   Voiceover provides a number of features that allow visually impaired users to see the tactile image being output in detail. Adjusting the line thickness of the picture, enlargement of the image, and more. To use the related features, you need to add the functions to the rotor. To add such functions, follow these steps:

   • Go to Settings > Accessibility > Voiceover.
   • Find and run the rotor button.
   • Scroll the screen to find “Braille Zoom”, “Braille thickness”, “Rotate braille horizontally”, “Rotate braille vertically”, “Invert braille”, and double tap each item to select it.
   • If the message “Selected” was added to each item, it is added to the rotor.

2. Using Image Inversion
   Inverting an image is a function that converts an image’s outline from being embossed to being engraved. When you run the Invert Image function, the image outline appears engraved within the tactile frame of the square shape; here’s how to use it:

   • Focus on any image object. (e.g. application icon on the home screen)
   • Notice that the image is displayed in the Dot Pad 320 graphics area.
   • Move the rotor of the Voiceover and place it to “Invert braille”.

   • The image reversal is turned off.

3. Enlarging an Image
   Voiceover provides the ability to magnify the image output to the Dot Pad 320 so that you can see tactile graphics in detail. The default image scale is 1.0 and can be magnified up to 10.0. The image magnification function can be used as follows:

   • Focus on the object with an image. (e.g. focus on any application on the home screen)
   • In the rotor options, select “Braille Zoom”.
   • Swipe one finger up and down to adjust the magnification ratio.
   • The currently focused graphic appears in the graphics area to match the magnification ratio you specify.

4. Scrolling Images Horizontally and Vertically
   If the image is enlarged at a size that it is difficult to display it all at once in the Dot Pad 320 graphics area, you can scroll the image left, right, up, and down to see the full picture of the image. “Rotate braille horizontally” and “Rotate braille vertically” are these features. Detailed usage is shown below.
   Note: This feature can be used with the image magnified by more than 1.5 times.

   • Focus on the object that contains this image. (e.g. any application on the home screen)
   • Enlarge the image on the “Braille Zoom” rotor.
   • Align the rotor option with “Rotate braille horizontally”.
   • Swipe down with one finger to increase the value.
   • The graphics of the Dot Pad 320 scrolls to the left.
   • To scroll the image to the right, swipe up with one finger to lower the value.
   • If you do the same in “Rotate braille vertically,” the image displayed in the Dot Pad 320 scrolls up.

5. Adjusting the Image Line Thickness
   If you want to see the line thickness of the displayed image in the Dot Pad 320 as thicker or thinner, this feature allows you to adjust the line thickness; here’s how to use it:

   • Focus on an object that contains an image. (e.g. home screen application)
   • In the rotor options, select “Dotted Lines Thickness”.
   • Swipe one finger up or down to adjust the line thickness. You can adjust the values from 0.1 to 1.0.
   • The default value is 0.3.

Viewing Images Using Voiceover Recognition

When Voiceover does not recognize any object as an image, image information can be collected using artificial intelligence (AI) to view the relevant image on the Dot Pad 320. Take advantage of Voiceover recognition introduced in iOS and iPad OS 14 versions. When you analyze an image of a random object through Voiceover recognition, that image is simultaneously sent to the Dot Pad 320. Voiceover outputs the image generated by the AI in speech and braille. We’ll walk you through the details in the sections below.

1. Creating Image Recognition Gestures
   To use Voiceover recognition to send an image to the Dot Pad 320, you must manually add a gesture that allows you to run Voiceover recognition; here’s how:

   • Go to Settings > Accessibility > Voiceover.
