As we are speeding our way into the 21st century our interaction with technology is increasing exponentially. Our efficiency has improved and the KAI is here to improve it even further. Our vision while developing the KAI was that we wanted a device that would tie our digital environments together seamlessly. Our solution: make the KAI as sleek as possible without affecting its functionality.


The problem with our first prototype (which was built on an orange kitchen glove) was that it resembled products that were trying to do the same. We wanted to make use of our gestures, not restrict them. But when Abhishek Satish made a breakthrough by developing his patent-pending technology of tracking fingers using the reflection of invisible light, new life was given to the company. It freed up the hand to do other things while wearing the KAI and allowed users to rest their arm letting them use it for long hours on end.

How it’s done

There are four sensors on the device which detects electromagnetic rays within a specific bandwidth and uses it to sense the location of the four fingers. It sits comfortably on the palm of your hand and can be worn while typing, using a mouse and more. Time is saved and work gets done.

What’s the big deal?

  • You don’t need to take off the KAI while typing. Hitting keys on a board aren’t the only thing that constitutes typing. One has to format, refer and insert other kinds of files too. This requires constantly switching between the keyboard and the mouse. This additional interaction is cut down by the KAI as you can simply use the KAI for all those activities without taking it off and on again and again.


  • Imagine having to work 9 hours a day where you need to use a device which gets in everything’s way. You need to take it off 10-20 times a day just to switch between tasks. You don’t have to do that anymore. The KAI sits flat on your palm leaving your fingers free to hold things.


  • During long work hours, one just wants to kick back and not exert oneself too much. The KAI lets you do just that. Since it is wireless and probably the least restrictive device you will ever use, you can use just the same while resting your arm.


  • The KAI recognises common hand gestures like pinches and grabs and understands exactly what’s being done. Using our Kai Control Centre you can customise these gestures to do exactly what you want them to do.

First the keyboard, then the mouse, then touch and now gestures. This is a step into the future, making the present better along the way. At Vicara, our vision is to build a world where human efficiency and cutting-edge technology go hand in hand for the betterment of all.
