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** "Tangible Meets Gestural"discusses defining new interaction techniques using tokens to explore large data sets. It mentions that physical actions impact thinking and learning in four ways: induction, off-loading, repurposing, and physically distributed learning. (expand on this topic). This paper also  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 Based Interations  **BlowBrush**  "BlowBrush" is a novel idea that looks into tangible painting systems using a windmill. A user can blow on **Drawing with Everyday Objects**  In addition to allowing  the windmill user  to paint leaves or other objects flip through photos and rotate them, Piknik will also offer the capability of drawing  on screen. As we are developing this application, existing photos using magnets. However, instead of just using magnets,  we need will be embedding the magnets in styluses (acting as paintbrushes)  to look into allow  the criteria that BlowBrush used user  to analyze their own system. This criteria have a more natural interaction with the application. "I/O Brush" is similar idea, it  is consisted a drawing tool aimed at young children to be able to draw with everyday objects. The authors  of these items: methaphorical ffordance, enjoyable engagement, tangible manipulation, spatial interaction, embodied facilitataion, I/O brush built a device that can select the color from anywhere in the real world  and expressive representation. 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.  **I/O Brush**  "I/O Brush" BlowBrush  is another idea that looks into into tangible painting systems using  a drawing tool aimed at young children windmill. A user can blow on the windmill  to be able paint leaves or other objects on screen. BlowBrush used this criteria  to draw with everyday objects. The authors of I/O brush built a device that can select analyze and study  the color from anywhere in effectiveness of their application. This criteria is consisted of: methaphorical ffordance, enjoyable engagement, tangible manipulation, spatial interaction, embodied facilitataion, and expressive representation. As we are developing this application, we need to look into  the real world criteria that BlowBrush used to analyze their own system.
