This section gives a brief discussion of a typical web (and video) conferencing package available called Electromeet. As web conferencing is a fairly mature market, most of the features should be common across a range of packages. The main reason that Electromeet is used is because of its video capabilities, remote labs and ability to run proctoring (remote testing) sessions.
Electromeet has many communication channels that can be used for the purpose of conferencing. These include text, talk, video, whiteboard, desktop sharing, YouTube video sharing and recordings. All elements can be used in conjunction with each other to create an effective conferencing session. Conventional online communication channels such as text, audio and video are used alongside the whiteboard, desktop sharing, YouTube video sharing and recordings to enhance the conferencing experience.
The whiteboard is a useful tool that allows a presenter to upload a document such as a PowerPoint, PDF and Word document. The whiteboard also has drawing features that will allow a presenter to annotate their presentation documents. The whiteboard features when used alongside video, audio and text act as a virtual classroom for all remote participants.
Desktop sharing is a useful tool for allowing all participants to see the desktop of the sharer’s computer. This is particularly useful when a presenter wants to demonstrate a software package relevant to the presentation topic. In addition, the desktop sharing feature allows participants to gain control of the presenter’s computer (once provided with access rights). This is a powerful tool giving participants a hands-on experience rather than having them merely passively watching a demonstration.
The YouTube video sharing feature allows presenters to share YouTube videos with everyone participating. This will mean that the student doesn’t have to sit and listen to someone present only uploaded documents to the whiteboard, but can also watch some relevant videos.
All sessions can be recorded. This allows for a session to be recorded and watched again in the future, or provide participants who are absent from a presentation to catch up later.
Overview of Electromeet
Figure 1: Electromeet Overview
To communicate with other users and the instructor, the student uses the talk and texting feature.
• The talk feature simply works by clicking on the “push to talk” button. If the button turns yellow it means that someone is already talking and you have entered the queue to talk. Once the button talks green, it is your turn to talk.
• To send a text message, simply type in the text box and next to the “Send” button. Click on the “Send” message to send your text.
• There is also a text feature to send texts to specific users. Below the typing box is a tab with the options to select whom you would like to talk to.

There are also other ways in which you can communicate with the instructor:
By clicking on the smiley face you can convey your current emotions on the teaching topics.

Using / Viewing the Whiteboard
The whiteboard is a convenient and easy way for instructors to communicate. The whiteboard has the ability to upload documents that have been previously created (PowerPoint, PDF, etc.). The top left of the whiteboard contains all of the drawing features, allowing the presenter to draw over any of the uploaded documents to communicate more effectively what they are presenting. They can also conduct their presentation by simply drawing on blank slides with all of the available drawing features.
Figure 5: Whiteboard
The whiteboard feature is typically used by only the instructor. However, instructors can provide students with the use of the whiteboard. If that is the case, participants will be granted drawing permissions.
Figure 6: Whiteboard Features
If this is the case, students can use the pointer, pen, line, circle and square drawing tools, highlighter, text box, eraser, zoom, create question, web tour, formula and pointer features associated with the whiteboard.
The pointer, pen, line, circle, square and highlighter tools are simple drawing features. The textbox allows you to place test on the slides.
The eraser allows to erase all of you drawings. If a mistake is made, you need to use the pointer feature, select what you want to delete and press “delete” on your keyboard.
The zoom features allow you to zoom in and out of the slides.
The question feature allows tour to create multiple choice questions.
The web tour allows you to access the internet and show everyone what you are accessing online. Every time you access another site you must highlight the website URL and press enter to refresh the web tour for everyone.
The formula feature allows you to write a simple mathematical formula using text or import a more complicated formula from mathematical formula writing software.
The pointer feature allows you display a pointer on everyone’s screen to assist with communication.
The whiteboard features can be used to enhance the slides uploaded onto the whiteboard. The below figure shows an uploaded PowerPoint with selected whiteboard features used to draw over the uploaded slide.

Streaming a Video
To access the video streaming feature simply click on the video icon that is highlighted in the figure below.
Figure 5: Video Streaming Icon
Once the feature has been opened, a Multi Video window will open. This window allows you to configure you videos you wish to stream. The configuration of a video stream is very simple. All that is required is a webcam, frame rate and video size be selected. The default fame rate is already set up to deliver good video quality, so a frame may not need to be selected. To select a video device, you simply need to click on the video device drop down box. This drop down box allows you to see all video devices running from your computer. Once a video device is selected, the picture size needs to be selected. Simply click on “Big” or “Small” to select video size. Once the video device configuration is completed click on the “OK” button. The configuration of a video device can be seen in the figure below.

Watching a Video
Instructors will sometimes want to demonstrate examples physically and will require the video streaming or webcam feature. To view anyone’s webcam, simply right click on his or her name, select watch video then select the desired webcam. This can be seen below.
Figure 8: Viewing a Streaming Video
Once the video has been selected, it will display on the right hand side of Electromeet.
This is a convenient display since it allows the instructor to operate video and whiteboard simultaneously. There is a capability for two webcams to stream simultaneously.

However, depending on screen size, the webcam display won’t show all videos on the side of the page. To allow all the video to be seen, the Multi Video Viewer tab can be clicked and dragged to manipulate it to your liking.
It can be dragged to overlap the whiteboard or be dragged to fit into the features tab at the top of the Electromeet page.

Putting it all Together
Once all the features described above have been properly enabled, you can hold a successful conferencing session. Examples are provided in the two figures below. The figures below are set up to highlight the text, audio, whiteboard, multi-video and video viewing working simultaneously. Having these features run simultaneously allows for a more successful and interactive conference to be held. The talk, text and video features running in conjunction with the whiteboard creates interactivity amongst an online learning environment.
