Tactual Labs is an innovator in multi-touch sensing technology. It is leading development of the world's fastest, most responsive touch and stylus user interfaces. Its next generation touch sensors and architecture will create a zero-latency, real-time user experience for touchscreens, trackpads, and creative applications including gaming.

Fast Multi-Touch Sensor

Tactual's first public innovation is Fast Multi-Touch (FMT), a revolutionary 40-microsecond capacitive multi-touch sensor, that is more than 300x faster and precise than today's 13-15 millisecond touch solutions.

Tactual's Fast Multi-Touch (FMT) technology enables zero-latency, multi-touch sensing with cross-industry applications for end-users, developers and OEMs. FMT enables development of zero-latency transparent touchscreens for touch and stylus input as well as opaque gamepads and trackpads. Zero-latency touch input makes multi-touch applications from productivity to gaming more immersive, enabling new mobile, console, PC, virtual-reality and augmented-reality UI mechanics and designs.


Patent Pending Technology

FMT's technological superiority over today's sensing and touch processing solutions includes:

  • FMT scans for input up to 4,000 times a second, over 300 times faster than today's 60 to 85 Hz solutions.
  • FMT recognizes touch input in approximately 40 microseconds. By comparison, today's capacitive touchscreens and trackpads used in smartphones, tablets, PCs, gamepads and consoles report a touch-input event in 13-17 milliseconds.

What this means on a practical level is the ability to capture the subtleties of human movement in computing. Today, finger and stylus gestures are poorly captured; digital objects visibly lag behind the finger; digital ink strokes lag behind the pen tip. More immediacy and accuracy can significantly enhance the user experience and reward developers.

FMT includes fundamental innovations in sensor pattern design, signal injection, signal reception and signal processing. These innovations were necessary to improve sensor responsiveness without compromising on device cost, ergonomics or energy efficiency. In addition, FMT was designed to scale better to higher scan rates, larger sensing surfaces and noisier electromagnetic environments. FMT's smarter signals can more flexibly adapt in real-time to in-device and ambient electro-magnetic noise.

FMT is compatible with any conductive material - from Indium Tin Oxide (ITO), used in most touchscreens today, to emerging metal-mesh, silver-nanowire and graphene conductors.

But touch input sensor latency is not the only bottleneck to immediate response. That is why Tactual is developing both input sensing and OS/application touch architecture solutions. Our research estimates three components account for the total delay between a touch and its on-screen response:

  1. 13-17ms input sensing
  2. 25-100ms OS/application software that processes touch events and generates output for the display
  3. 17 ms device display (for today's 60 Hz refresh-rate displays)

Tactual's FMT sensing technology addresses the first component. Tactual's future touch architecture solutions address the second component for a combined lag time savings of 38-117ms.


Tactual's senior engineering team consists of veterans in interactive surface solutions educated at CMU, MIT, Harvard and University of Toronto (birthplace of multi-touch), with industry experience at Microsoft, Mitsubishi and Draper Laboratories.
