Design boundaries and constrains

The paramount values, when approaching the design and development of this product, were: Convenience of use, Readability of the product, Prevention of accidental activation and Suitability for use by adults and children alike. The design approach at this case was very focused, in understanding the strict boundaries and constrains of the electronic components, as well as, targeting an extremely wide user audience with various abilities. The end result reflects this exact focused approach, leaving a precise product volume within a 2-3mm tolerance.

Functional hierarchy

Despite this severe limitation, a clean and memorable design was created. A combination of basic forms providing a platform for readability and for an understanding of the products functional hierarchy.
