I came into contact with Joe and Katherine who have both been blind for most of their lives. They provided me with invaluable insight into the daily life of the blind.
There are a variety of ways Joe and Katherine organized their things, but I managed to break it down into three distinct categories: Labels, Kinesthetic Memory, and Hierarchical Organization.
Joe and Katherine proved that they could identify an incredibly diverse array of forms simply by the way it felt.
In order to design containers that were distinct from one another, I altered the jars shape, size, and texture. This gave me 27 unique forms; a little more than half the number of unique forms Joe and Katherine can identify.
The three sizes and shapes of the jars lend themselves to store a variety of different things. For example, the circular container is better for storing canned goods. Wheras the triangular jar is better fit for storing things that pour, like cereal.

Tact is a line of storage containers designed to be blind accessible.

By taking advantage of the blind's refined sense of touch, food can be identified by the various sizes, shapes, and textures of the jars they are within.

By using form association to identify products, the blind no longer need to label and relabel many of their food items; which can be costly and time consuming.
