Introduction:

Mental models for deeper user interactions 

Buttons, sliders, and rotating knobs remove the human element in digital communication. Interaction with this hardware is simple because its position is defined within the whole, i.e. a slider position is defined by location in the slot it slides in. This simplicity enables the hardware controls to be easily learned and assimilated into mental models. To attain a deeper connection between technology and users, technology needs to connect to the subconscious, the intuitive space that follows the logic of our mind. In the same way traditional user interfaces are simple because they immediately communicate their position, hardware that connects to the subconscious must intuitively define a unique language to communicate its position to the user. Emotive Groove is a series prototypes I am exploring to build this new frontier of connection between user and technology.

Mnemonic encoding

"Moonwalking with Einstein" by Joshua Foer explores professional memory champions' mnemonic method to quickly memorize large amounts of unrelated information. Using visualized reconstructions of physical spaces known as "Memory Palaces", visual mnemonics were both incredibly moldable and secure. If visual mnemonics were strong, tactile and visual mnemonics should be even more powerful.

Enhancing freedom of expression

I am interested in how applying metrics to different types of user interactions allows one to express in different ways and communicate different information. By increasing the feedback channels to sensory high locations (include science about data pickup on fingers), individuals can express more intutitively and connect more closely with their technology.
