This document discusses principles of universal design and multi-sensory systems. It covers how multi-modal systems use more than one sense for interaction, like visual and audio, while multi-media uses different media like video and images through the visual mode. Speech, non-speech sounds, handwriting, gesture, and touch are examined as potential input/output modes. Challenges and examples of applications are provided for each sense and input type. The document concludes by noting how design can be inclusive for users of different abilities, ages, and cultural backgrounds.

2. UNIVERSAL DESIGN PRINCIPLES
• equitable use
• flexibility in use
• simple and intuitive to use
• perceptible information
• tolerance for error
• low physical effort
• size and space for approach and use
3. MULTI-SENSORY SYSTEMS
• More than one sensory channel in interaction
• e.g. sounds, text, hypertext, animation, video, gestures,
vision
• Used in a range of applications:
• particularly good for users with special needs, and virtual
reality
• Will cover
• general terminology
• speech
• non-speech sounds
• handwriting
• considering applications as well as principles
4. USABLE SENSES
The 5 senses (sight, sound, touch, taste and smell) are used by
us every day
• each is important on its own
• together, they provide a fuller interaction with the
natural world
Computers rarely offer such a rich interaction
Can we use all the available senses?
• ideally, yes
• practically – no
We can use • sight • sound • touch (sometimes)
We cannot (yet) use • taste • smell
5. MULTI-MODAL VS. MULTI-MEDIA
• Multi-modal systems
• use more than one sense (or mode ) of interaction
e.g. visual and aural senses: a text processor may speak
the words as well as echoing them to the screen
• Multi-media systems
• use a number of different media to communicate information
e.g. a computer-based teaching system:may use video,
animation, text and still images: different media all using
the visual mode of interaction; may also use sounds, both
speech and non-speech: two more media, now using a
different mode
6. SPEECH
Human beings have a great and
natural mastery of speech
• makes it difficult to appreciate the complexities
but
• it’s an easy medium for communication
7. STRUCTURE OF SPEECH
phonemes
• 40 of them
• basic atomic units
• sound slightly different depending on the context
they are in, these larger units are …
allophones
• all the sounds in the language
• between 120 and 130 of them
• these are formed into …
morphemes
• smallest unit of language that has meaning.
8. SPEECH (CONT’D)
Other terminology:
• prosody
• alteration in tone and quality
• variations in emphasis, stress, pauses and pitch
• impart more meaning to sentences.
• co-articulation
• the effect of context on the sound
• transforms the phonemes into allophones
• syntax – structure of sentences
• semantics – meaning of sentences
9. SPEECH RECOGNITION PROBLEMS
• Different people speak differently:
• accent, intonation, stress, idiom, volume, etc.
• The syntax of semantically similar sentences may vary.
• Background noises can interfere.
• People often “ummm.....” and “errr.....”
• Words not enough - semantics needed as well
• requires intelligence to understand a sentence
• context of the utterance often has to be known
• also information about the subject and speaker e.g. even if “Errr....
I, um, don’t like this” is recognised, it is a fairly useless piece of
information on it’s own
10. THE PHONETIC TYPEWRITER
• Developed for Finnish (a phonetic language, written as it is
said)
• Trained on one speaker, will generalise to others.
• A neural network is trained to cluster together similar
sounds, which are then labelled with the
corresponding character.
• When recognising speech, the sounds uttered are
allocated to the closest corresponding output, and the
character for that output is printed.
• requires large dictionary of minor variations to correct general
mechanism
• noticeably poorer performance on speakers it has not been
trained on

12. SPEECH RECOGNITION: USEFUL?
• Single user or limited vocabulary systems
e.g. computer dictation
• Open use, limited vocabulary systems can work
satisfactorily
e.g. some voice activated telephone systems
• general user, wide vocabulary systems …
… still a problem
• Great potential, however
• when users hands are already occupied
e.g. driving, manufacturing
• for users with physical disabilities
• lightweight, mobile devices
13. SPEECH SYNTHESIS
The generation of speech
Useful
• natural and familiar way of receiving information
Problems
• similar to recognition: prosody particularly
Additional problems
• intrusive - needs headphones, or creates noise in the
workplace
• transient - harder to review and browse
14. SPEECH SYNTHESIS: USEFUL?
Successful in certain constrained applications
when the user:
• is particularly motivated to overcome problems
• has few alternatives
Examples:
• screen readers
• read the textual display to the user
utilised by visually impaired people
• warning signals
• spoken information sometimes presented to pilots whose
visual and haptic skills are already fully occupied
15. NON-SPEECH SOUNDS
boings, bangs, squeaks, clicks etc.
• commonly used for warnings and alarms
• Evidence to show they are useful
• fewer typing mistakes with key clicks
• video games harder without sound
• Language/culture independent, unlike speech
16. NON-SPEECH SOUNDS: USEFUL?
• Dual mode displays:
• information presented along two different sensory channels
• redundant presentation of information
• resolution of ambiguity in one mode through information
in another
• Sound good for
• transient information
• background status information
e.g. Sound can be used as a redundant mode in the Apple
Macintosh; almost any user action (file selection, window active,
disk insert, search error, copy complete, etc.) can have a different
sound associated with it.
17. AUDITORY ICONS
• Use natural sounds to represent different types of
object or action
• Natural sounds have associated semantics which can
be mapped onto similar meanings in the interaction
e.g. throwing something away
~ the sound of smashing glass
• Problem: not all things have associated meanings
• Additional information can also be presented:
• muffled sounds if object is obscured or action is in the
background
• use of stereo allows positional information to be added
18. SONICFINDER FOR THE
MACINTOSH
• items and actions on the desktop have associated
sounds
• folders have a papery noise
• moving files – dragging sound
• copying – a problem …
sound of a liquid being poured into a receptacle
rising pitch indicates the progress of the copy
• big files have louder sound than smaller ones
19. EARCONS
• Synthetic sounds used to convey information
• Structured combinations of notes (motives ) represent
actions and objects
• Motives combined to provide rich information
• compound earcons
• multiple motives combined to make one more complicated
earcon
20. EARCONS (CTD)
• family earcons
similar types of earcons represent similar classes of action or
similar objects: the family of “errors” would contain syntax and
operating system errors
• Earcons easily grouped and refined due to compositional
and hierarchical nature
• Harder to associate with the interface task since there is
no natural mapping
21. TOUCH
• haptic interaction
• cutaneous perception
• tactile sensation; vibrations on the skin
• kinesthetics
• movement and position; force feedback
• information on shape, texture, resistance, temperature, comparative
spatial factors
• example technologies
• electronic braille displays
• force feedback devices e.g. Phantom
• resistance, texture
22. HANDWRITING RECOGNITION
Handwriting is another communication mechanism which we are
used to in day-to-day life
• Technology
• Handwriting consists of complex strokes and spaces
• Captured by digitising tablet
• strokes transformed to sequence of dots
• large tablets available
• suitable for digitising maps and technical drawings
• smaller devices, some incorporating thin screens to display
the information
• PDAs such as Palm Pilot
• tablet PCs
23. HANDWRITING RECOGNITION
(CTD)
• Problems
• personal differences in letter formation
• co-articulation effects
• Breakthroughs:
• stroke not just bitmap
• special ‘alphabet’ – Graffeti on PalmOS
• Current state:
• usable – even without training
• but many prefer keyboards!
24. GESTURE
• applications
• gestural input - e.g. “put that there”
• sign language
• technology
• data glove
• position sensing devices e.g MIT Media Room
• benefits
• natural form of interaction - pointing
• enhance communication between signing and non-signing users
• problems
• user dependent, variable and issues of coarticulation
26. … PLUS …
• age groups
• older people e.g. disability aids, memory aids,
communication tools to prevent social isolation
• children e.g. appropriate input/output devices, involvement
in design process
• cultural differences
• influence of nationality, generation, gender, race, sexuality,
class, religion, political persuasion etc. on interpretation of
interface features
• e.g. interpretation and acceptability of language, cultural
symbols, gesture and colour
