Multimodal Interaction in Distributed and Ubiquitous Computing

Marc Pous and Luigi Ceccaronibdigital

ICIW 2010 - The Fifth International Conference on Internet and Web Applications and Services

May 9 - 15, 2010 - Barcelona, Spain

• Why multimodality?

• Multimodal distributed services deployment

• User tests and conclusions

SUMMARY

In our cities, urban services practically have not changed in a century

1: Location-based services

What is an ICD?(Interactive Community Display)

INREDIS

3G = ACCESSIBILITY + UBIQUITY + INTEROPERABILITY

INREDIS ICD

Management of distributed services that offer the capability of processing and synthesizing multiple modalities of interaction

DISTRIBUTED INTERACTION SERVICES

• Voice services– Voice recognition

• Via microphone, real-time streaming converting the voice signal into text

– Voice synthesis

• Sign language service– Spanish sign language recognition

• Via webcam, real-time streaming converting the image into text

• Emotion service– Emotion recognition (voice + image)

• Via webcam and microphone, real-time streaming

• Avatar service– Emotional avatar– Sign-language speaker avatar

DISTRIBUTED SERVICES

SIGN LANGUAGE SERVICES

DISTRIBUTED SERVICES

VOICE SERVICES

How to consume multimodal distributed services offered by an ICD?

W3C MMI Architecture

• W3C MMI Architecture

http://www.w3.org/TR/mmi-arch/

W3C MMI Framework

http://www.w3.org/TR/mmi-framework/

Proposed multimodal interaction framework

• ICD Architecture

ICD ARCHITECTURE

(1) Interaction identification

(2) Main page- Map or avatar- Command buttons- Content- Scenario options

(3) Contextualized map with services

(4) Avatar with map and Street View service

ICD DESIGN and INTERFACES

USER–CENTERED DESIGN

• User profiles (Personas)– Blind users– Deaf users

• Unable to read– People living or visiting a city

• Scenarios– Context-aware informative scenario– Emergency scenario

IMPLEMENTATION

USABILITY TESTING

• PLI (People Led Innovation) methodology

• Preliminar usability tests with a limited number of users

• But the ICD implementation received good feedback!

CONCLUSIONS and FUTURE WORK

• Implementation based on the W3C MMI Architecture idea• Platform able to integrate multimodal interactive distributed

services and offer interaction in real-time• Web-based applications and device-independent

implementation• Improvement of the user experience and accessibility of

people with special needs

What are we working on now?– Real-time interaction: delay reduction between interactions– Browser-based apps not being able to easily access device hardware– Synchronous interaction vs. Asynchronous technologies– Improvement of the distributed services orchestration– Enhancement of the mobile usability

MOBILE PHONES?
