"Tangible Meets Gestural" (**cite paper**) mentions the value of learning and thinking is greater when using physical objects. Touching physical objects can help children learn how to count and keep track of their activities. We will use the findings of this paper help us create physical objects to allow users to draw with (e.g. paint brushes).  1. Discuss Magnet **Magnet  Based Interations Interactions**  Gestures made in 3D Space is unique to every user. If two users made box like gestures over the phone, both of their gestures would be somewhat different. This is due to users not being able to reproduce each others gestures in 3D space within a certain threshold \cite{Sahami_Shirazi_2012}. As we are developing this application, we need to take into account this threshold to be able to recognize certain swipe gestures across all users.  **Drawing with Everyday Objects**  In addition to allowing the user to flip through photos and rotate them, Piknik will also offer the capability of drawing on existing photos using magnets. However, instead of just using magnets, we will be embedding the magnets in styluses (acting as paintbrushes) to allow the user to have a more natural interaction with the application. "I/O Brush" \cite{Ryokai_2004} is similar idea, it is a drawing tool aimed at young children to be able to draw with everyday objects. The authors of I/O brush built a device that can select the color from anywhere in the real world and be able to paint with that color on the tablet. It molded its every day object as a brush so users can easliy create the mental mappings and seamlessly work with the every day objects.
