Applications of Fin

Thumb is accessible to anywhere in the palm and its more natural too. So wearing a Fin will make your palm as a touch interface that enables the people to interact with Smartphones [Dial Numbers, Attending calls, SMS, Social media, Taking Quick Notes etc.] especially for visually challenged people since they sense the world through touch.


Fin can control your smart TV, to change the channels, control sounds by mere natural finger swipes.


Fin can control your car from being your cars key to controlling your phone while driving, navigate your maps, receive calls and read messages, change music, and other car utilities just by finger swipe without even taking your hands off the steering wheel  there by not distracting yourself from driving.


A big problem in all the wearable devices is the input of Instructions. In the much-Hyped Google glass, a voice instruction and a touch pad on devices is provided, but both the input methods are cumbersome in odd situations. Integration with FIN will be ideal for these wearable, as FIN can control the device with much ease and accuracy.
