Dr. Micah Yairi is the cofounder and CTO of Tactus Technology, a company bringing a new user interface to consumer devices and displays: dynamic touch surfaces that enable buttons to rise out of the screen on demand. When not needed, the buttons recede invisibly into the screen, returning the display to its original clear, flat surface. Before founding Tactus, Yairi worked at Los Gatos Research, where he led development efforts for microfluidic transdermal drug delivery systems and advanced optical sensors. He also founded Fortnight Solutions, a business-to-business “matchmaking” service that helped engineering companies locate solutions to technical problems.
