You can change the font by selecting it from the drop-down list at the top. The size of the text is determined by the current thickness selected. - Use to flood fill an area with the current colour (note that the flood fill may not display correctly if you subsequently use the pan or zoom functions). - Enters eye dropper mode, allowing you to pick a colour from the drawing canvas. Click the left mouse button on the whiteboard canvas to select the colour from the pixel at that location. If you have the RGB colour palette displayed,
the colour will also appear in the palette window. - The eraser acts in the same way as a large freehand brush with white colour. - Sets the current zoom level to 100%. - Zooms in on the picture. - Zooms out of the picture. - Use this like a laser pointer to highlight items to other users on the whiteboard without actually leaving any mark on the whiteboard. You can change the size and colour of the laser pointer by using the size and colour selectors. - Enters pan mode, allowing you to move the drawing canvas. Click the left mouse button on the whiteboard canvas and drag to pan. - Click to clear the contents of the whiteboard. - Click to undo the last drawing action. - Click to redo the last undo. - Enters select mode, allowing you to select
an area of the whiteboard for copy/paste operations. You can also click
on objects to select them, and move them by dragging. - Click to copy the contents of the whiteboard (or selected area, if any) to the system clipboard. - Click to paste the contents of the system clipboard into the whiteboard. - Click to cut the selected area and copy it to the
system clipboard. - Click to delete the selected area or objects. - Click to crop the image to the selected area. - Click to print the whiteboard (or selected area). - Click to bring up the gridlines window, allowing
you to have a grid on top of the whiteboard and optional snap-to-grid. - Brings up this window.
- Click on the line thickness you want to use. This will be the pen size for lines and unfilled shapes, and the font size for drawing text. |
 | Click on the drawing colour you want to use. - click to bring up an RGB colour palette window. |
 | Your video preview window. Click on the X below the
video window to stop sending your video to other users. Below the video window
is the audio recording meter: the circle lights up red when your voice is
being transmitted to other users, and the red bar shows the current recording
signal level of your microphone. |
 | Other user's video window. The triangle lights up
green when that user is speaking. |
 | Audio controls: Volume - Move the slider to the right to increase your headphones/loudspeaker volume (the volume that you will hear other users speaking). Microphone - Move the slider to the right to increase your microphone volume. Buffering - Move the slider to the right to increase the buffering of incoming voice data. This will only affect what you hear. Increasing the buffering reduces breakups, but increases delay. Disable Talking (optional) - Clicking on this button disables all other users from speaking. Only displayed if the user has disable interaction permissions. Grant Presenter (optional) - Grants another user presenter status. This button is only available if the conference room has been set up in presenter mode, where only one user can talk/draw. |
The conference room can support up to 4 users, each with video and/or audio. If you have enabled your webcam, your preview window will appear at the top, with the audio controls underneath. The other users will appear in the windows to the bottom.
Your video is transmitted automatically to the other users. By default the frame rate is set to 0.5 frames per second when you are not speaking, and 4.0 frames per second when you are speaking. This can be changed in the configuration files on the server.
Audio is only transmitted to the other users when you are speaking. The recording circle (under the video preview window) should light up red when you are speaking and your voice is being transmitted, and it should be white when you stop speaking. If this does not happen, you may need to adjust your microphone volume. Alternatively you can use "push-to-talk" mode: simply untick "Auto Transmit Voice". Then simply click and hold the left mouse button on the circle when you want to speak.
NOTE: if a user has not transmitted any audio or video, you will not see their name displayed.
Echos - echos are an indication that there is feedback (the speech is coming out of a user's loudspeakers and entering their microphone). This can be solved by ensuring that all users use headsets rather than loudspeakers. If this is not possible, the problem can be reduced by ensuring that all users untick "Automatic Recording", and use push-to-talk.
Break-ups - if you hear break-ups in the sound, it can have one of two causes. If parts of the speech are missing, it means that the talking user's microphone volume is too low for the automatic recording threshold. That user will need to either increase their microphone volume or untick "Auto Transmit Voice". If no speech is lost and you simply get breaks in the sound, it means that the packets are getting delayed. Check to make sure that you are not using any applications that are using your internet bandwidth (such as file sharing apps). If this does not solve the problem, try increasing the buffering slider in the Options window.
Delays - you should never get delays of more than one or two seconds. If you do get large delays, it can be caused by one of two things. First, if you see a green triangle or red circle lit continuously, it indicates that a user has an open microphone (continuously recording), which can cause delays to build up. The user who is constantly recording should either reduce their microphone volume or untick "Auto Transmit Voice". If you have "mic boost" enabled for your microphone, you should disable it (go to the advanced settings in the windows volume control). Delays can also be reduced by reducing the buffering slider, although this might increase break-ups in the sound. Large delays can also be caused if your internet connection is dropping packets.
