Ambient Intelligence
Internet of Things
Pervasive Computing
Physical Computing
Ubiquitous computing
Augmented reality
Human-centered computing
Smart device
• No more desktop-centered computation, but
distributed computation(“ubiquitous”)
• Objects become more “intelligent” and “smart”
• New information’s model
• New possibility of interaction with information
• Machines fit the human environment instead
of forcing humans to enter theirs

What’s happened?
Natural…experience!
“Natural interaction is defined in terms of
experience: people naturally communicate
through gestures, expressions, movements, and
discover the world by looking around and
manipulating physical stuff.”

Multi-Touch Devices (2)
Tangible Table / Wall
• Microsoft "Surface SDK" and "Windows Presentation
Foundation" include API, documentation and tool to
develop multi-touch apps on Windows 7 and Surface
• "Cocoa Touch" is a library to develop software for iPhone,
iPod Touch, e iPad. "Cocoa Touch" is included in iPhone
SDK.
• Android SDK include tool, emulator, debugger and library
to develop App for Android
• Gestureworks (by Ideum) is an interesting Flash multi-touch.
The Gestureworks software allows to develop multiuser and
multi-touch-enabled applications with Adobe Flash.
Multi-Touch Software
http://www.lukew.com/touch/TouchGestureGuide.pdf
Common Gestures
• Nails
• Gloves
• Dirty fingers
• Gestures (are they so easy?)
• Accuracy
Problems: Input
Gorilla arm problem
Problems: Accessibility
• Touch-based applications introduce new important
constraints in design of interface and interaction:
• Target’s dimensions must be fit to fingers’ dimension
(min 10mm)
Problems: Usability
Labels’ position: hands and fingers can hide information
Problems: Usability (2)
Gesture’s design: some actions can hide part of information,
too.
Problems: Usability (3)
Iceberg Tips: create a wider
invisible area
Adaptive Targets: device
tries to guess next button
pressed by user and zoom it Hell
Tips & Tricks
• Don’t assume that people will know that they can touch a
screen.
• Create an “attract state” that demonstrates interactivity while
nobody is using the device
• Make touchable things look touchable
• Design for fingers
• Make sure hands don’t cover up information necessary for
interaction
• Don’t rely on traditional mouse-based interactions, such as
hover & double click
• Use consistent and familiar gestures

Touchless interfaces
• Camera

QuiQui’s Giant Bounce
Game for children (4 - 9 years)
Game’s paradigm: story telling with animated characters
The actions of child activate specific behaviors of avatar
• The EyeToy is a color digital camera device, similar to a
webcam, for the PlayStation 2.
• The technology uses computer vision and Gesture recognition
to process images taken by the camera.
• This allows players to interact with games using motion, color
detection and also sound, through its built-in microphone.
• Limited success due to the low precision
Sony Eye Toy
• The console was released on November 19,
2006. About eight days after, 600,000 Wii’s were
reported to be sold.
• It has revolutionized game play and has
impacted society: anyone can play!
Nintendo Wii
• The Wii remote, or “Wiimote”,
interacts with a sensor bar by
using accelerometers, infrared
LED’s, and triangulation.
• In general, a player’s Wiimote
movements would determine
their character’s actions. A
gamer would have to move in
order to play.
Wii Technologies
• Wii and wiimote comunicate by Bluetooth
• TED 2008: Johnny Lee show how is possible
connect wiimote with a normal pc and use them
in innovative application:
– interactive whiteboard
– 3D head tracking
– finger tracking
• Many others researcher start to use wiimote in
academia projects: http://hackaday.com
Wii Hacks
• It is a motion sensing input device by Microsoft for the Xbox
360/XBOX ONE console.
• It enables users to control and interact with the Xbox without
the need to touch a game controller, through a natural user
interface using gestures and spoken commands.
Microsoft Kinect
Immersive user experience
Kinect’s magic
“Any sufficiently advanced technology is indistinguishable
from magic”
(Arthur C. Clarke)
Provided Data
Cursors (hands tracking)
Target an object
Avatars (body tracking)
Interaction with virtual space
• Depend by the tasks
• Important aspect in design of UI
Interaction metaphors
The shadow/mirror effect
Shadow Effect:
• I see the back of my avatar
• Problems with Z
movements
Mirror Effect:
• I see the front of my
avatar
• Problem with mapping
left/right movements
User Interaction
Game mindset ≠ UI mindset
Challenging = fun Challenging = easy and effective
Gesture semantically fits user task

Final considerations
Capture Volumes
The user is performing a hand gesture outside of the capture
volume. The camera will not see this gesture
Evaluate different settings and environment
Sensor with Camera use IR light and Sunlight can blind the camera!!!
• Check exposition during all day
• Verify that there isn’t direct light on the camera
These devices aren’t a Rugged devices:
• Check temperatures (+3/33°)
• Check humidity
Indoor/Outdoor
Comfortable positions
Your users are not GORILLAS!!!
User posture may affect design of a gesture
Input variability
Feedback, feedback, feedback,…
View of user:
• User Viewport
• User Overlay
… where actions performed for some other purpose or unconscious
signs are interpreted in order to influence/improve/facilitate the actors'
future interaction or day-to-day life (from Alan Dix)
• The interaction is not purposeful from the person side, but it is
designed “to happen”
• It “happens” in relation to signs which are not done for that (body
temperature, unconscious reactions such as blink rate, or
unconscious aspects of activities such as typing rate, vocabulary
shifts (e.g. modal verbs), actions done for other purposes, …
• It is designed for people acting
