A prototyping kit for iOS. Tramontana leverages the capabilities of the object that we have all come to carry with us anywhere, all the time, our smartphone. With libraries for Processing, Javascript and OpenFrameworks you can access the inputs and outputs of one or more smartphones to easily and quickly prototype interactive spaces, connected products or just something you’d like to be wireless. More information at: tramontana.xyz To use Tramontana and access all the features of your phone you need to use the open source Processing, javascript or openFrameworks libraries. You can use your device as actuator triggering remotely: - flash light; - vibration; - changes to screen brightness and color: - playback of video, audio, and images as you can see from the screenshots; You can use the device as a sensor reading: - orientation; - magnetometer; - accelerometer; - distance sensor; - audio jack; - changes in the power source; - touch events; You can also trigger remotely the camera and upload pictures to Dropbox. Tramontana now interfaces with Wekinator and you will be able to use touch or accelerometer inputs from your device with the machine learning software.
