We asked a number of people to use a ratcheting and non-ratcheting screwdriver on a variety of normal household items. The items tested included a CD player, a towel holder, chairs, a fan, a bedframe, a vaccum cleaner, and an airsoft gun. The idea was to provide a wide array of objects and a large sample size in order to gain a new perspective on how people use the tools and the problems they often encounter. | We asked a number of people to use a ratcheting and non-ratcheting screwdriver on a variety of normal household items.

Market Research
We asked a number of people to use a ratcheting and non-ratcheting screwdriver on a variety of normal household items. The items tested included a CD player, a towel holder, chairs, a fan, a bedframe, a vaccum cleaner, and an airsoft gun. The idea was to provide a wide array of objects and a large sample size in order to gain a new perspective on how people use the tools and the problems they often encounter.
Project Schedule
The schedule for the remaining part of the project is layed out in the Gantt chart below. The milestones' occurences are denoted by a yellow triangle and have a breif description next to them. The big milestones will be the completion of Prototype 1 and Prototype 2, the Final Report, and the Design Expo. The chart is in one week increments with the red parts of the bar denoting the parts of teach task that have been completed and the cream-colored yellow represents the time remaining to complete the task. All tasks will initially be completed as a group, and will be divided up as seen fit when we are doing tasks.
