Voice free

No need to say a word. Usable in quiet as well as noisy situations.


Achieve complete mouse control, without a mouse or touchpad.

How It Works

Patented Percept-D™ Technology


Head motion or Eye Gaze



Smile, Eyebrow Motion, etc.



Pointer Motion, Clicking, Dragging, Scrolling & more!

Our simple hands-free gesture recipe can be implemented in multiple forms.

  1. In Head-worn Wearables: Percept-D™ can be embedded inside wearable devices such as smart glasses, Head Mounted Displays (HMDs) or phone/music headsets. In this situation, Percept-D™ can use the motion sensors (such as MEMS gyroscopes or accelerometers) and proximity or touch sensors that may be already present in those devices to detect user gestures.
  2. In Devices with Front Facing Cameras: Percept-D™’s can be implemented as computer vision software that runs on devices with front facing cameras such as tablets, smart phones, laptops, computers, etc.. Here Percept-D™ will monitor the user’s gestures via the front facing camera and provide mouse control accordingly.

Percept-D™’s simple gestures provide powerful hands-free, voice-free and mouse-free control, as follows.

  1. Control the wearable that has Percept-D™ inside. E.g. If Percept-D™ is embedded inside smart glasses or AR/VR Head Mounted Displays, the user can control those devices as well as the apps or games running on them in a hands-free fashion.
  2. Control other devices using the wearable that has Percept-D™ inside. E.g., control devices such as smart TVs, computers, tablets, smart home appliances, etc. using head-worn wearables (such as smart glass, BT headset, music headphones, etc.) that have Percept-D™ inside. In effect, when your wearable has Percept-D™ inside, it can act as a hands-free controller of other devices!
  3. Control devices with front facing cameras. E.g. when you load Percept-D™ software on devices such as such as tablets, smart phones, laptops, etc. you can control them hands-free using facial gestures captured by their front facing cameras. In this scenario, user is not required to wear any wearables to achieve the control.

About Perceptive Devices

We provide Percept-D™, a patented technology for true hands-free and voice-free control of diverse electronics devices for improved productivity, safety and accessibility. It allows for control via simple facial gestures that can be captured by webcams or sensors mounted on eyewear. (US Patents # 9013264, 9785242, 10137363, 10895917, 10191558, 10254844, 10884493 and 10558272.)

Our award-winning software, Smyle Mouse, provides complete hands-free mouse control of Windows devices via facial gestures. This can be life changing for people with severe disabilities, as they can communicate, work and play without the use of hands and voice. Smyle Mouse is being utilized by private individuals as well as employees of Fortune 500 companies and large governmental organizations.

Percept-D™ is available for licensing in enterprise, industrial, manufacturing, gaming, and other applications, including for use with Augmented / Virtual / Mixed Reality devices.
