One of the features I’m excited to have implemented is Switch Integration.
Switches are essentially buttons that come in all sorts of forms and sizes. Some are actually big physical buttons that can be pressed with any limb that can still move, or a head nudge. Others detect the slightest muscle movement with almost no force. There are some you can blow into, and still others that detect blinks.
You would usually connect any of these switches to a hub that can communicate with the smartphone or tablet through Bluetooth. In the states, the Blue2 from Ablenet is quite popular, and in Europe the iSwitch from Pretorian is more wildly used. They both provide a physical button that can be pressed, and can have other switches connect to them for more options. Also, both are mobile and chargeable so you can use them on the go.
In Open Sesame, switches can be used in two ways:
1. They can be used to Start tracking, so if a person is non verbal he/she could use the switch to start the head tracking. Also, by pressing the switch again during tracking, will cause Sesame to restart tracking (or “Reposition”), so you have a safety net in case tracking starts to drift.
2. The other mode replaces the dwell interface altogether. So you don’t need to hover and wait for a tap or swipe to be performed, but rather point with your head, and then activate the switch to tap. If you hold the switch down, you can then swipe or scroll by moving your head as long as the switch is pressed.
You can find both options in Sesame’s settings, under the General tab and scroll down to the Interaction section.
Hope this helps! Let me know in the comments what you think 🙂
