The BJOY Ring mouse emulator is a device which behaves like a conventional mouse and is specially designed to adapt to the controls of a wheelchair, using the inclination of the chair’s joystick to move the cursor and using the external switches to perform the normal functions associated to a mouse’s clicks. This device is aimed at users who use wheelchairs and who want to access the computer.

The main features of the device are:

  • It is non-invasive and easy to install.
  • It can be adapted to the assembly position and to the user’s mobility by calibration.
  • Automatic recognition of the assembly inclination at the time of the connection. It can be installed in an inclined position (up to 45º).
  • Compatible with all wheelchair models (the model must be chosen which is adapted to your wheelchair).
  • It has two customisable switches to perform the functions associated to the mouse clicks.
  • One of the switches allows for the cursor movement to be disconnected.
  • It does not require any installation software: the operating system recognises it directly. The configuration software which is supplied with the product allows the device to be calibrated so that its response is optimum.
  • Configurable and customisable using the BJOY configuration software which is supplied with the product.
  • The configuration is saved on the device and not on the PC which facilitates the use of the same device on different computers without having to reconfigure it.
  • The typical configurations can be done offered by the operating systems for the mouse (change of pointer type, click options, etc.).

The BJOY Ring mouse is made up of the following parts:

  1. Ring
  2. Fixing screw
  3. Protection cover
  4. Switch input box
  5. USB connection
  6. Assembly spanner
Parts of the BJOY Ring

Fig. 1. Parts of the BJOY Ring.

 

The joystick allows the cursor moving in all directions. The two configurable switches allows the click functions of the mouse to be performed: left click, right click, double click and drag-drop. The function of each switch can be assigned via the BJOY configuration software which is supplied with the product, selecting one of these functions for each switch input. See section 4.2 of the “BJOY configuration programme” in this user’s guide to obtain detailed information on the configuration.

By default, the entry A performs the left click function and the entry B the right click function.

In order to assemble the equipment the following steps must be followed:

STEP 1.
Take the handle off the wheelchair joystick and the protective hood if any.

STEP 2.
Insert the ring.

The optimum position for assembling the ring is with the tightening screw in the chair’s forward direction.

In the case that it can not be set up in the optimum position, it is VERY important that the ring is set up in positions with 90º turns in relation to the chair’s forward position.

If it is set up in different positions the mouse will not respond properly.

STEP 3.
Tighten the mounting screw using the spanner provided with the device. It is important not to force the tightening screw.

STEP 4.
Put on the protective hood. It is important to always put on the protective hood.

STEP 5.
Reassemble the joystick handle onto the wheelchair.

STEP 6.
Install the configuration software and do the calibration.

In order to correctly assemble the equipment it is important to take into account the following indications:

  • Protect the switch input box from liquids.
  • Avoid water entering via the USB cable.
  • Use the USB extension lead if the cable does not reach directly.
  • It is recommended to use assemly inclinations of under 45º.

In order to start using the BJOY Ring mouse the USB connection cable must be plugged into the computer’s USB port.

IMPORTANT: In order to access the computer the wheelchair must be first disconnected.

Although the device adapts to the assembly position, when it is connected to the computer’s USB port it must be calibrated in order to obtain the best response from the joystick’s movements. The following steps must be followed in order to perform the calibration:

  • Install the provided BJOY configuration software.
  • Do the calibration (See section “Software configuration” in this manual).

Once the calibration is done the device can be used like the joystick of the wheelchair. To move the cursor on the computer screen you just need to move the joystick in the desired direction.

To avoid the cursor moving on the computer screen when you want to drive the wheelchair, you have to deactivate the mouse by closing the session on the computer, disconnecting the USB cable or configuring the “Deactivate” option using the configuration software (See section “Software configuration” in this manual).

If due to a slight change in the position of the joystick the mouse moves slightly without moving the lever, the device can be deactivated and then reconnected in order to recognise a new resting position. If this occurs frequently or the position of the wheelchair joystick is not stable, the “minimum inclination” value can be modified using the configuration software (See section “Software configuration” in this manual).

The two external switches which are connected to the entries indicated as A and B of the box for switch entries must be used to do the clicks. By default these entries are assigned to the following functions:

Entry A: Left click
Entry B: Right click
B kept down: Deactivate BJOY Ring

If only 1 switch is going to be used it can also be configured so that it does the deactivate function (See section “Software configuration” in this manual).

This function can be configured using the BJOY configuration software (See section “Software configuration” in this manual).

For the correct use of this device, you are recommended to:

  • Do not use it in moving vehicles
  • Do a calibration if there is a substantial change to the wheelchair joystick’s resting position.
  • Do a calibration if irregular behaviour is noted.

The functioning of the mouse can be customised using the configuration software (See section “Software configuration” in this manual).

The BJOY configuration software allows you to configure the mouse behavior according to the user needs.

1. Are settings made to BJoy transferable between devices?

Yes, Settings are saved to the Bjoy hardware, therefore if you connect it to another electronic device settings will remain the same.

There is the possibility to save and load a configuration. You can see the details in section “software configuration – Configuration options”.

2. How many times do I need to calibrate it?

Calibration is only needed once. As long as the Bjoy’s mounting position remains the same, calibration is valid.

IMPORTANT: if you restart Bjoy ring, it beeps several times. Do not move the joystic during this beeping.
 
If you feel joystic does not work properly and mounting position has not changed, switch Bjoy off and on again trying not to move the joystick during restarting.
 

3. How much can the wheelchair be leant back?

  1. Perform calibration while wheelchair is it’s the most common leaning position.
  2. If wheelchair is going to be leant back:
    1. Deactivate BJoy Ring
    2. Place wheelchair in the desired position
    3. Activate again BJoy Ring to enable allow it to recognize the new position

IMPORTANT: When BJoy Ring is restarted it starts beeping. Please do not move the joystick during these beeps.

At this point the device should work properly without recalibrating it.

NOTE: If there is a lot of difference between current and original wheelchair’s position deveice might need recalibration (maximum recommended tilt is 45º).

4. Is there any adjustment helping with situations of much trembling?

In these cases we suggest to increase the value of “Dead zone width” within “calibration” tab (see below image). Depending on its value, this parameter allows that joystick’s movement does not directly translates into movement of the pointer.

5. Is BJoy Ring compatible with smartphones and tablets iOS?

Apple’s tablets and smartphones do not support mouse pointer as an access method. Since BJoy Ring emulates the functioning of a mouse, these devices are not compatible.

Only devices with Windows, Android and  Mac (laptops and desktop) are compatible with BJoy Rings.

6. How to select a language

  1. Open BJOY software
  2. Click on “Tools” > “Options”
  3. Select desired language from the drop-down menu “application language”

7. ¿Can a BJoy be connected to an Android smartphone or tablet?

It is possible to use BJoy with smartphones and tablets running on a compatible Android operating system. To do that, connect either transmitter or receiver using a USB-OTG cable (not provided).

Android devices must have:

  1. USB Host o USB-OTG connection (almost every new Android devices have them).
  2. Control buttons embedded in the screen (“back”, “home”  “multifunction”), this way you will be able to manage all your device’s functionalities using BJOY.

NOTE: users who do not have control buttons embbeded into the screen can experience access limitations. However, exists software in the market that emulates phisical contact buttons in the screen. If this is your case and you need technical support please contact us.

      3. Movile device must run at least on a 3.2 Android version or higher.

NOTE: To ensure optimal performance of the BJOY Ring  using your movile device please take into account that it must be calibrated and configured using BJOY’s software in PC running on Windows.

8. Can a BJoy be connected to an iOS device?

BJoy can be connected to an iOS device that allows mouse access (only laptops and desktop computers. Tablets and smartphones do not have mouse access functionality enabled).

9. ¿Is there an iOS version of BJoy’s software?

No, an iOS version of BJoy’s software has not been developed. However, BJoy device can be configurated into a Windows operating system device and since the configuration is stored inside the BJoy, it can be later connected into an iOS device that allows mouse access (laptop or desktop. Tablets and smartphones do not offer this access method).
