Testing

TestingBinaryOutput - boolean display widget
TestingGaugeOutput - float display widget (range 0.0f-1.0f)
TestingPushButtonInput - momentary boolean input widget
TestingSliderInput - float input widget (range 0.0f-1.0f)
TestingTextFieldInput - string input widget
TestingTextFieldOutput - string output widget
TestingToggleButtonInput - latching boolean input widget

Behaviour

AssociationLearner - learns simple input -> output mappings (functions) by example
BeanShell - simple BeanShell (Java) script component

Information I/O

AtomBlogger - posts blog entry when post property is set to true, using atom XML blog API. See setup notes for info on setting up your own blog (the default is http://www.curioushome.blogspot.com)
EmailSender - sends emails! (when the message input property changes)
FileExporter - has a local GUI which allows a user to select a local file; copies this to a local web-server and publises the URL.
DynamoMediaViewer - displays a range of content types - specified by URL - using local (Windows) viewer applications (e.g. word, powerpoint, HTML, AVI).

Physical I/O

AudioCaptureManager - See javadocs for more info. Uses JMF (which must be installed and configured) to capture audio and make available to audioframework components via AudioCaptureDevice sub-components' source property to:

AudioProcessor - sink can be connected to another source. Hosts a configurable chain of audio processors. See configUrl for waveform images.
AudioAverage - extension of AudioProcessor which outputs average sample value at the end of the chain.
AudioSelectValue - extension of AudioProcessor which outpus a particular sample value at the end of the chain.

JMFVideoCaptureManager - See javadocs for more info. Uses JMF (which must be installed and configured) to capture video frames and make available to videoframework components via JMFVideoCaptuerDevice sub-components' source property to:

SimpleVideoProcessor - sink and optionally referenceSink can be connected to another source. Hosts a configurable chain of audio processors. See configUrl for waveform images.
VideoFrameAverage - similar to SimpleVideoProcessor buts outputs average pixel value of the input image.
VideoFrameExporter - then trigger is set (and optionally continuously at a specified rate) captures images and exports them as URLs to locally hosted files.
ARToolkitGlyphTracker - uses the jARToolkit binding for ARToolkit; each component tracks a specified glyph (specified by glyph data file URL) in the input image.

Phidgquip factory - creates sub-components to represent Phidgets currently connected to this machine and their I/O elements (each servo, output, etc.). Currently - due to Java binding limitations - supports output only (Servo, digital output), and only one of each kind of board per computer.
SmartItsFactory - creates sub-components to represent ACCORD-programmed SmartIts with standard IO boards currently communicating with the SmartIt receiver assumed to be connected to the COM1 serial port.

Details (partial)

Association Learner

equip.ect.components.associationlearner.AssociationLearner

Author/source

Chris Greenhalgh, Shahram Izadi (Nottingham)

Description

Can be trained with a 1D mapping between input and output. Training is performed by presenting an input to in and then presenting the desired output value to trainingOut. The output out will always output the mapping (if any) associated with the current input. Where the input is a number(Java type) and the output is a number (Java type) then the Association Learner will fix a piece-wise linear function to the trained associations, i.e. an input between those already seen will result in an output interpolated between the trained outputs. When the input is a number (Java type) and the output is not then the output will be mapping of the trained input that is closest to the current input.

Input properties

in: Object
trainingOut: Object

Output properties

out: Object

Persistence

Implements equip.ect.Persistable. Uses equip.ect.PersistenceManager persistObject and loadObject to persist (Java Serialize) the bean itself. On load the trainedInputs (TreeSet) and associations (Hashtable) are restored.

BeanShell

equip.ect.components.bsh.BeanShell
Subcomponent: equip.ect.components.bsh.BeanShellArg

Author/source

Ted Phelps (Sussex/Lancaster)

Description

Host and execute a single bean shell script.Set the "inputNamesString" property to a whitespace-separated list of script input arguments; the BeanShell component will then create corresponding BeanShellInput sub-components, the "value" property of which is linked to the corresponding script argumennt. Similarly, set the "outputNamesString" property to create BeanShellOutput sub-components. The script is re-executed each time an input changes.

Persistence

Implements equip.ect.Persistable. Uses equip.ect.PersistenceManager persistObject and loadObject to persist the lists of input and output arguments and the script in a text file.On load these are restored. (Could probably use default persistence, but that didn't exist at the time.)
