Conclusion

We believe that the Navi-key logic, because of its versatility, would be very suitable for use in other electronic products as well. We have played around with using the concept in wrist wearables, and as long as there is room for at least a two-line display-one for content and one for command-it works just fine. Consider the example of cars, which are undergoing an information technology (IT) revolution. The dashboard has traditionally been a collection of user interfaces for heating, radio, lights, and other components, and the design philosophy has been that each function has a dedicated knob, or lever. With increasing functionalities, this philosophy leads to the airplane cockpit syndrome, which is probably not the desired scenario. The Navi-key logic could be used for many functions in a car. Because it is compact, it would not clutter up the instrument panel or even the steering wheel. And where else can you find a UI concept known by 300 million users?

This story could have been taken out of an innovation textbook where novices with their fresh insight and courage challenge the conventions. The Navi-key design team suggested demolishing the pillars of the successful Nokia 2110 user interface. The story also featured mentors who spent and exerted much time and effort without claiming credit. It also has an element of skunk work with the creation of the prototype, which finally sold the concept to the product champion in management. Finally it featured all the engineers who actually developed the phone and the software. This was the product development fairytale. Future advances can be made only by rushing back to the lab!
