Tactus Technology, a provider of on-demand tactile surfaces, has closed the first portion of its Series B funding round with new investors from Asia joining existing backers. The company develops a user interface for mobile, computing, CE and automotive devices—completely transparent physical buttons that rise up from a touchscreen surface on demand.
The new investors, including Ryoyo Electric, join Thomvest Ventures and other backers who have reinvested in the Series B round. As part of the investment, Ryoyo will become the exclusive sales partner and distributor for Tactus components and display technology subsystems in Japan. Tactus previously received $6 million of Series A funding—and a $12 million valuation— in December 2011.
