Integrating Arduino-Bluetooth Sensors with iOS

One area that I've been exploring recently is Bluetooth communication between sensor-circuits and iOS apps. I wanted to share one of these studies, based on some of the examples provided from the good folks at Adafruit. It consists of a sensor that can detect the presence of a flame, and send that information over Bluetooth to an iPhone app, which displays the reading from the sensor.

Integrating the GRT into an iPhone Project

In this blog post, I'll show you to add the Gesture Recognition Toolkit to an iPhone app. Created by Nick GIllian while he was a post-doc at MIT, the GRT is a "cross-platform, open-source, C++ machine learning library designed for real-time gesture recognition".  I had known from this issue on GitHub that the GRT has been used in iOS development. I was only able to find one example of this in action, which this guide is partially based upon.

Tactile Interactions with Multi-Touch Apps

As much as multi-touch devices have enabled new forms of music creation and performance, they are still lacking in one thing that traditional, acoustic instruments have: tactile feedback. However, Dutch designer Samuel Verburg of Tweetonig created a solution to this problem with TunaKnobs; rotary knobs that will attach to any capacitive surface (Wired UK has a great write-up on the project).
