In 2016, upwards of 1.6 billion people in the world are using smartphones. Smartphones are becoming a staple piece of technology for many citizens in North America and around the World. Smartphones and touchscreen devices enable users to navigate around their city better, to communicate with others more freely, and to operate applications which can promote happy and productive lives. Currently, there exist a limited number of practical devices for quadriplegics to use touchscreen devices - this is where we step in.
The LipSync is an electronic device which allows quadriplegics the ability to use compatible touchscreen and computer devices without the use of their hands. The user is able to manipulate a cursor on their device screen using a mouth-operated joystick with integrated sip and puff controls to simulate the actions of "tap" and hitting the back button, respectively. With longer sips and longer puffs, additional secondary features are enabled including a "tap and drag", "long tap and drag" and the possibility of more specialized functions as per the user's needs.
The LipSync is design specifically for portable devices, it does not require AC power, but it will work with any device including desktop and laptop computers that support mice through a universal serial bus (USB) or the Bluetooth connection.
The LipSync is an open-source hardware project where all of our 3D printer files, component lists and microcontroller code are made public. In the spirit of accessibility, our housing can be 3D printed, the electronic components are readily available and the assembly is as straightforward as possible.
The LipSync was envisioned as a holistic solution that takes in to consideration not only the interface but how the system is to be mounted on the user’s wheelchair. The actual electronics of the device is on part of the implementation. There are no standardized methods to which wheelchairs are designed. Wheelchair manufacturers can use round or square tubing. They often also use tubing which is not compatible with other manufacturers so that customers must buy accessories from them. As a result, there is not a standard location or clamping mechanism to mount assistive technology on the chair.
Wheelchairs are also customized to the user, including the height, width and seating position of the user. The seating on the wheelchairs are customized to minimize the incidents of pressure sores. As a result, the mounting system for assistive technology such as the LipSync also has to be customized. In addition to the instructions to assemble a LipSync, we have included instructions on how to mount a LipSync. A combination of off-theshelf and custom 3D printed components are provided in order to help makers create a fully integrated and customized solution for the user.
Now the maker community and disability community can meet, collaborate and work together constructing a LipSync over a period not much longer than a weekend. We hope these new relationships will continue spurring innovation within the maker community.
There are 3 main aspects we will be addressing in our project:
- Developing an easy to build, but robust electronics assembly that novice to experienced makers can build;
- Developing a device housing which can be 3D printed by makers either at home or at dedicated facilities;
- Creating mounting options for a variety of wheelchairs with 3D printed parts and/or commercially available components.
SMARTPHONES AND ACCESSIBILITY
Smartphones, by their very nature, are intended to be used while on the go. Traditional assistive technology designs for the desktop and laptop computer are not portable in nature, so they cannot be easily applied to smartphones. While single and dual input systems exist for smartphones, they are slow and frustrating to use for users with more capabilities of movement. Single and dual input switches are appropriate for users that can only make one or two movements consistently. The LipSync is...Read more »
