The concept of inputs is interesting to me both from a what can be input but also from the broader concept of what information you can capture and share.
Here are two very interesting Kickstarter projects that I things are quite interesting input devices.
The concept is creating a night vision add on for the iPhone. It presents an extremely interesting market area – the addition of capabilities to the iPhone that extend it into more and more intriguing areas (same for the Android phones).
This next project is a file sharing system that ends today (11/30/2013) around 4 pm EST. If you are interested in this one they are 1500 dollars from their goal.
It opens the world up to your phone in terms of being able to connect to and share with anyone. Personally if I were looking from a DropBox or Box perspective I would snatch this project up and incorporate it into their products.
Inputs are interesting because they are in the end game changers. What you can consume on the device you are using creates a solution. How you use that solution then makes you either more successful or you stop doing it.
Truly in the end its why I love Kickstarter and Indiegogo. It is a chance to see if in the end there isn’t a better way to input data than the method you are using now.
