Signal Processing for Multimodal WebIrekDefée Department of Signal Processing Tampere University of Technology

W3C Web Technology Day

current status
Current status
  • Web is developed for traditional data and computer I/O: text, keyboard, mouse
  • This is simple and effective but not a natural

way of human interaction with the world

  • Humans interact via

perceptual system

human perceptual system
Human Perceptual System
  • Human perceptual system has multiple senses: visual, acoustical, haptic

(touch, body position, temperature)

and actuators (vocal tract, muscles, motoric system)

  • The perceptual system is intrinsically MULTIMODAL: multiple senses and actuators operate in perfectly coordinated way
perceptual information technology
Perceptual Information Technology
  • Information technology is evolving towards natural MULTIMODAL human interaction:
  • Touch gestures

revolutionized mobile devices

  • Intelligent speech input

is available

  • There is more to come:

new sensors, cameras

and intelligence

signal processing role
Signal Processing Role
  • Perceptual Information Technology requires sophisticated signal processing

and it is hard due to:

- Complex input signals

- Complex information encoding

- Complex databases of knowledge

  • Highly sophisticated algorithms and

huge processing power are required

multimodal web
Multimodal Web
  • The trend towards perceptual information is noted at the W3C:

Extending the Web to allow multiple modes of interaction: GUI, Speech, Vision, Pen, Gestures, Haptic interfaces, ...

  • Multimodal Interaction Activity:

- Multimodal Architecture and Interfaces

- EMMA

- InkML

- EmotionML

slide8
EMMA
  • Extensible Multimodal Markup Language for Annotations

- containing and annotating the interpretation

of user input

- transcription into words of a raw signal, for

instance derived from speech, pen

- interpretation is to be generated by signal

interpretation processes, such as speech and ink

recognition, semantic interpreters

ink markup language
Ink Markup Language
  • data format for representing ink
  • input and processing of handwriting,

gestures, sketches, music using

traces of pen

Trace

attributes

emotion markup language
Emotion Markup Language
  • Annotation of material involving emotionality
  • Automatic recognition of emotions from sensors
  • Generation of emotion-related system responses: speech, music, colors, gestures, synthetic faces
  • Emotion vocabularies and representations:

<emotion category-

set="http://www.w3.org/TR/emotion-

voc/xml#big6"> <category name="surprise"

confidence="0.9 </emotion>

department of signal processing
Department of Signal Processing
  • Signal processing has a key role as a front-end for the Multimodal Web
  • Department is on the forefront of research

in the natural information processing:

- Multimedia information analysis, retrieval and

databases

- Audio information analysis : speech and

music

- Media information handling: representation and

compression
