A stylus as a creative implement, every stroke is unique, providing an expression of the user’s individuality.

Next generation experience that brings natural writing feel to tablets for an unparalleled, highly personalized user-computer interaction and the potential to improve user engagement for tablet makers

Today, using a stylus on a phones and tablets generates the unpleasant feel of writing on glass: the experience is either sticky or according to most users akin to “roller-skating”. Tactai’s Dynamic Haptics technology onboard the Active Stylus reference reproduces the authentic feel of pen-on-paper to imbue a sense of deeply personal interaction.

Problem: Current haptic feedback is limited to simple pre-determined vibrations that are always the same for all users. Interactions do not feel natural and leave the impression of sliding on glass.

Solution: Tactai-powered Active Stylus reference design provides on nearly zero latency tactile interaction that faithfully reproduces the feeling of pen or pencil on paper.


Tactai’s Dynamic Haptics(tm) can be leveraged for automotive and many others industrial panel displays. User interface buttons, and other controls such as sliders, and rotating knobs can have authentic tactile feeling and sensation comparable to mechanical equivalents.

Problem: Fixed touch-screen panels are used in a variety of markets, from automotive to home appliances. They provide users with a wide range of functionality. However, these panels can be difficult to navigate since they do not provide feedback during user interaction. To the human user, they feel flat and lifeless.

Solution: Tactai Dynamic Haptics ™ delivers a much richer user experience through natural touch feedback. Flat visual buttons and controls come alive. User interaction is simplified. No need to divert attention during driving – which compromises safety – to look for the right button to press. You can actually find it just by touching.


What if you could feel like drawing on canvas or write on parchment paper on a standard glass tablet?

TactaiINDEX® is a unique hand-held instrument that enables to capture the feeling on any real-world surface and texture and then recreate the same feeling on a glass tablet allowing for infinite permutations of user interactions.

Based on Tactai’s patented haptic technology and powered by the Tactai Haptic Module(tm), the Index enables for the first time the capture and rendering of any human-surface interaction with unparalleled realism.



Missing haptic feedback is the major disadvantage for the touchscreen as an input device. Most market ready smartphones give only visual feedback, which requires the user’s visual attention. But current research illustrates the importance of good haptic feedback to touchscreen devices.

As tactile stimuli go much deeper than visual or auditory and they are recalled for much longer users will demand more and more from touchscreens — more interactivity, better responsiveness, deeper personalization and increasingly more powerful digital experiences.

Problem: Current phones have vibrotactile elements (i.e., actuators) that are meant only to provide for the familiar smartphone “buzz” and several other predetermined and timebound effects.

Solution: Tactai technology can be embedded into any smartphone to create fine-grained sensations, which can be localized to particular areas. It can give users a sense of touching a keyboard key or sensing different surfaces textures when they tap a part of the touchscreen. Because the tactile feedback is generated in real-time (not prerecorded) and is personalized to match each individual user’s interaction profile, it closely mirrors how we interact with physical objects in the real world.

Specifically, for smartphone implementations of Tactai technology, the following is required:

  • Be able to stream an analog or at least 8 bit signal with as little latency as possible and at a rate of at least 1kHz to the haptic integrated circuit (IC) embedded already in the smartphone, and the haptic integrated circuit to be able to drive the native actuator without filtering the input signal.
  • The native actuator should not be an ERM but some reasonable quality LRA that the integrated circuit allows to drive out of its resonance frequency. An LRA with a flatter response curve is ideal.


Virtual reality is anticipated to be a revolutionary computational interface. Even today, it is being used for gaming, industrial design, and medical training. Current virtual reality systems rely on simulating sound and vision, but largely ignores touch.

TactaiTOUCH™ reference design is the next generation touch-enabled fingertip-wearable controller for virtual reality applications. To create truly powerful experiences in the virtual world, we delved deep into the physics and biology of how humans touch and feel in the natural world. From these insights, we developed a touch-capable controller for use in VR to touch, feel, and interact with virtual objects with life-like realism.


Problem: Virtual reality lacks the sense of touch. This makes interacting with objects in virtual reality feel ghost-like. The lack of touch feedback breaks the illusion the virtual environment.

Solution: TactaiTOUCH™ enables users to connect with the virtual world like never before. It helps create compelling immersive experiences in augmented and virtual reality by adding the natural sense of human touch into the existing audiovisual sensory channel.
