OI Platform

16

OI Platform

• Open source platform

• To make it easier to develop effective interactive systems that exploit multimodal interaction techniques in modern application settings (mobile, ubiquitous, context sensitive)

17

OI Platform

• Open source platform for developing multimodal interfaces

• that enables quick replication,• that enables iterative user-centred design,• that contains a rich and extensible set of

modalities,• that enables a focus on innovation

(new modalities or forms of multimodality),• that supports dynamic selection and

combination of modalities to fit the ongoing context of use.

18

OI Platform

- Repository of modalities (components)- Repository of Fusion/Fission Mechanisms (components)

- Runtime Kernel

Tool for the application designer/developer

Using/Assembling the components

Tool for the provider of

components

Adding new components

19

OI platform

• Who are the users?

• Three types of users

1. Programmers• Providing new components (populating the platform)

• New device• New modality• New fusion/fission mechanism

2. Multimodal Application Designers• Assembling components

to define multimodal interaction3. End-users of multimodal applications• Interacting with the multimodal application• Adaptation at run-time

Run- time

Design time

OI platformRuntime kernel

21

Outlines

• Kernel• Overview• OI Components• CIDL, PDCL

• Current Features

• Next Features

22

Overview

• Useful high level programming language support:• C/C++, Java, Matlab, Python

• Plug n Play behavior.

• Lightweight skeleton platform.

23

Components

• Platform does not specify/define a Component Model (!!)

• Platform sees the external software as components

• components are assumed to behave like objects.

• Software/Component delivered as reusable independent unit with exported/imported I/O interfaces.

• Platform Kernel aims for the interaction of heterogeneous components

24

Component: OI point of view

Facets can be seen as services provided by a component

A Component is a set of facets

This is how any external software is seen by the Kernel

25

Reusable Independent Unit

• Software

• With API

• With installation/configuration doc

• Without explicit dependencies with other components

• Tested and validated

• Much likely a library (!!)

•  Impossible to test new modalities with an exe, for instance.

26

Exported/Imported IO

• Components only declare communication interface

• Enforce the requirement for independence

• Export IO (functions, etc.) when providing a functionalityDisplay an image

• Import IO for requesting a functionalityAn event handler

27

OpenInterface CIDL

• Designed to describe Independent and Reusable component.• (Intentionally) Not as expressive as WSDL (etc.)• Restricted on purpose to cover common attributes

of various programming languages• Describes component interface using a

programming language independent description (XML).• Not intended to be written by human• Generation tools are not yet available though

(being developed)

28

I/O Interface

• Functions provided by a component facet

• 3 types of functions

• SinkWith no return argument

• SourceWith return argument

CallbackWith no return argument, for importing external

functions

29

I/O interface: types

• Only supported languages common types

• Common primitives types

• Bool, integer(8,16,32,64bit), float, double, String

• Array of primitives types

• Complex types

• Objects

30

Runtime, Pipeline

• Pipeline description language to setup a running application initial connections.

31

Pipeline configuration

• Components• Remote or local

• Connections• Simple direct link• Multicast (Publisher/Subscriber)• (Temporal) Fusion

• Execution• Pin initialization values• Threaded execution

32

Current Features

• Supported Platform

• Linux and Windows• Supported Languages (with minor restrictions)

• Java• C/C++•Matlab

• Description languages

• CIDL, interfaces description• PDCL, static pipeline description

• Temporal Fusion components• Simple components distribution • Specification on how to write a language plug-in• Specification on how to write custom connectors

33

Next Features

• Installation Packages • Windows installer, debian package

• Pipeline • Kernel API component for controlling application dynamic

connections• Description languages tools

• Semi-Automatic CIDL generator•Graphical tool for pipeline composition

• Supported Platform• Other OS

• Supported Languages

• .NET framework• Connectors• More connectors plugins

Introduction

• What? : Graphically create an assembly of (OI) components

• At first: Technical (PDCL) Description

• Objective: OI Interface

• Not only a graphical editor but an IDE

• Actually: static assembly of components

• Next version: dynamic assembly of components

• Why?:

• Fast prototyping

• Runtime Testing and Monitoring

47

Demo

• Fast prototyping

• Create assembly

• Run the assembly

• Change Multimodal Interaction

48

Roadmap

• Introspection

• Runtime connection

• Monitoring of the components execution

• Usage data capture
