PRESENTER: Tobii Dynavox software is continuously improving, so there may be slight differences between the actual software and our training materials. Control is an intuitive way of interacting with your computer using eye tracking. Designed for people with conditions such as ALS, cerebral palsy, and spinal cord injuries, Control makes it easy to navigate and control your computer using only your eyes with complete independence. You might be wondering how does eye tracking work? First, the eye tracker at the base of the computer sends out near-infrared light, which is reflected in your eyes. Those reflections are picked up by the eye tracker's cameras. Through advanced filtering and calculations, the eye tracker determines where you're looking on the screen, putting you in control. Tobii Dynavox eye tracking technology can track one or both eyes across a variety of conditions having overcome barriers like bright sunlight, glasses, head movement, and positioning. Control introduces a concept called interaction first, which mimics the natural way you would use a computer with a mouse. This means you first navigate to the object on screen that you want to interact with by looking at the icon. And then choose what function you want to perform whether that's right click, double click, or something else. To open the Google Chrome browser, for example, you would activate the double click option. The gaze trace provides a clear visual of where you are looking on the screen. This trace follows your gaze, locking if a fixation is detected. This happens when you stare at one spot long enough. To unlock, simply move your gaze away. But to interact, select the activator icon to bring up the interaction menu. Let's take a closer look at this menu. Every time you select the activator icon, the interaction menu opens in the center of your screen like this. Notice that a magnified image of the selected area is displayed in the middle with a menu options surrounding it. This centralized radial menu improves eye tracking accuracy and efficiency. You'll find all of your main interaction functions in this menu including double click, left click, scroll, right click, click and drag, opening an on screen keyboard, and adjust target for fine tuning your initial selection. Let's watch how easy it is to use the tools in computer control to navigate your computer. Imagine you want to look up today's weather online. First, fix your gaze on the Google Chrome icon. Select the activator icon to open your menu and then choose double click. Now that your browser is open, fix your gaze on the address bar. Again, select the activator icon and choose keyboard to enter text. Notice how word prediction makes this process easy. Select enter on the keyboard to start the search and then close the keyboard. To scroll through your result options, fix your gaze anywhere on the screen, select the activator icon, and select scroll. Look toward the bottom of your screen to start scrolling down to slow down the scrolling speed, keep your gaze closer to the scroll icon or look up to go back. When you have found the website you want, close the scroll tool. Now fix your gaze on the link, select the activator icon, and select left click. Now you're ready to read the weather and you did everything with your eyes. For more options with Control, simply gaze down out of the screen area to bring up the off screen menu. Here you can access the app switcher, enable continuous click, pause eye gaze, and even more like adjusting settings and calibrating the software to your eyes. Control even provides quick start guides right within the software to orient you to all the controls available. All in all, Control provides eye gaze users with speed and precision, reduced eye fatigue, and more successful interactions. The bottom line is Control allows you to use the apps you choose and pursue the goals that matter to you. Explore more about Control in the Tobii Dynavox learning hub.
