The use of magnets to paint on the screen or to flip through images is a rich interaction on its own but is there a way to combine touch and magnet based input (physically and mentally). TUIC \cite{Yu_2011} looks into just this idea. It allows tangible interaction directly on multi touch devices. It embeds objects with circuits that simulate touch input to allow the mobile device to detect the object. There are three methods that "TUIC" achieves this, spatial (static touch patterns), frequency (dynamic modulation of touch), and hybrid (a combination of spatial and frequency). Although this would not directly apply to Piknik since it is possible to detect magnets without touching the phone, we will be looking into how we can detect different sizes of magnets and various locations. This can be done using the magnet's intensity or frequency modulation (as described in TUIC). Frequency modulation could be used in a unique way to build custom hardware to modulate the magnetic field. However due to the timeframe of this project, this will be considered as future work.  "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. styluses or  paint brushes). **Magnet Based Interactions**
