Adam Altman Joe Morales Chris Sandstrom Assistive Typing Device Documentation Part 3 1. To improve our design, we added length to the device using plastic utensils and silverware. Before we had the problem of not being able to see what we typed but with the added length gave us the ability to watch and correct our typing. We scanned our design and a sketch of its application below. 2. Accuracy: Our final device solved the problem of accuracy by including pennies on the end. These pennies are durable and their area matches up with the area of a keyboard key nicely. These pennies are attached to the end as a point to focus the energy and pressure onto the desired key. This results in less errors and more efficient writing. Comfort: Our initial device felt very uncomfortable when held in the mouth because we just held it by the plastic piece. We corrected this by wrapping the end in a ball of masking tape. This ball softens the force on one’s teeth and also presents a wider surface area so that it is both easier to pick up and easier to keep in the mouth. There are also no sharp edges on a ball of tape unlike the plastic spoon so there is no tearing of the mouth.
