A cosmetic wallet compact including a housing having a first casing, a second casing and attachment means, such as hook and loop fastener strips, to attach the cosmetic wallet compact to a handheld device. First casing is adapted and sized to hold and retain credit card(s), identification card(s) and folded bill(s) in an interior cavity. First casing incorporates a receiving slot and a window through which its contents may be seen and physically manipulated. At the window, a retaining press is provided which keeps cards in place and from unintentionally exiting the receiving slot after being inserted. An ejection guide aperture is further provided to selectively guide contents out of the receiving slot. Second casing has an interior which defines a palette of color cosmetics and a mirror panel.

An activity classifier system and method that classifies human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, the transformed skeleton data comprising scaled, relative joint positions and relative joint velocities. The system also includes a gesture classifier comprising a first recurrent neural network that receives the transformed skeleton data, and is trained to identify the most probable of a plurality of gestures. The system also has an action classifier comprising a second recurrent neural network that receives information from the first recurrent neural networks and is trained to identify the most probable of a plurality of actions.
