Current offerings skew heavily toward cameras that take marginal to unusable pictures.
My first direction was a fairly conventional shape. The side handles are larger than the body to protect the buttons and screen. This is a pretty familiar camera shape to kids, and they understand how to use it.
In review, a consideration of left handed kids leads to a one handed camera. The handle was designed to lay horizontal. This idea was more interesting to me.
After making some foam models to look at proportion and how they are held, I notice that the kids enjoy the more conventional shape and tend to use two hands anyway with the one handed camera. An insight happens while watching kids play with a kaleidoscope. I am reminded of how they make paper towel rolls into telescopes and decide the final version will use a horizontal tube as the main shape.
Grip is removable and interchangeable to allow for personalization.
