Scope Large Display Sharing (1)

• Situation
• Collocated users shares a large display in a home
• Remote users (in / out of home) can join with
  collocated users
• Users have personal second displays (mobile
  phones, PDA, etc.) with them
• Two or more communications can be done via one
  large display (collocated users do not
  communicate / collaborate with each other
  necessarily)
• Application Category communication, collaboration

- Collaboration - Communication
- Data Manipulation - Non-sharable Info.
Network
Separate Task
- Collaboration - Communication
4
Scope Large Display Sharing (2)

• User Benefit
• Large display can be used for several purposes /
  tasks simultaneously
• Multiple tasks can be processed on one large
  display
• Multiple views (modes, data) for one task can be
  shown to grasp overview or relationship
• Discussion Items
• What kind of collaborative applications?
• How to share large display among different users?
• How to use several display (large display and
  personal second display) in collaborative tasks
  and deal with privacy?
• Large display can be used to provide contextual /
  spatial information?
• Second display can be used for privacy
  information?
• What kind of device allows to have a natural
  interaction with large display (e.g. laser
  pointer as a pen or pointing devices)?
• How to use personal second display for
  interacting with a large display?

5
Scope Info Sharing for Communication (1)

• Situation
• Networked users and devices share information
  (knowledge, contents, sensed events, etc.)
  collected at each place / site
• Users get necessary information via the network
  by their personal mobile devices or home
  appliances
• Sharing information requires communication among
  the users concerned
• Application Category communication, entertainment

Personal Mobile Terminal
Car
Current Social Network
Appliances
Advanced Social Network
SNS Server
PC
6
Scope Info Sharing for Communication (2)

• User Benefit
• Users can communicate and share information
  everytime and everywhere by personal mobile
  terminal
• Users can get information necessary and adequate
  for their locations or situations
• Discussion Items
• What kind of applications / devices are adequate?
• Portable? Wearable?
• How to identify the user and its position?
• How to recognize the users situation?
• What are good interaction design for the user to
  retrieve necessary information from the social
  network?
• How to help users negotiation with information
  owners?
• What is required to strengthen social connections
  among users through process of information
  sharing?

7
Scope Activity Modeling (1)

• Situation
• Users activities are sensed by networked sensors
  and appliances
• Activities User-Device, Device-Device, User-User
  Interactions
• Users activities are collected and stored as
  activity logs
• By analyzing activity logs, try to find activity
  patterns typical to some social group
• Activity Patterns User / Social Profile, Social
  Behavior
• Application Category efficient appliance control

User-Device Interaction
Appliance Sensor Network
Device-Device Cooperation
Social Network
User-User Interaction
Activity Log
- User / Social Profile - Social Behavior
Social group can be defined hierarchically in
various granularity. (e.g. City, Community of
some interest, Family, Organization, Friends,
Individual)
8
Scope Activity Modeling (2)

• User Benefit
• Total efficiency optimization within a social
  group (e.g. energy consumption)
• Default settings of appliances (e.g. default
  channel on TV)
• Discussion Items
• What kind of meaningful activity patterns can be
  found?
• Applications making the best use of the activity
  modeling
• Tradeoff between the psychological cost and the
  user benefit on logging user activities
• Conflicts among users in the same social group

9
Scope Tabletop Collaboration (1)

• Situation
• Users are surrounding a tabletop display to
  collaborate on some task in a home
• Users have close relationship with each other
  (e.g. family, friends)
• Application Category collaboration

Home
10
Scope Tabletop Collaboration (2)

• User Benefit
• Users can collaborate closely by looking and
  manipulating the same object in front of them
• Collaboration gets more efficiently by facing
  each other as users can make good use of gesture,
  facial expression, atmosphere, etc.
• Discussion Items
• For what kind of tasks in the home a tabletop is
  appropriate?
• What is the role of a tabletop in the home?
• How does a tabletop interact with the other
  devices on the network?
• How to interact with a tabletop (e.g. what kind
  of input device)?
• What kind of good applications rises if tabletop
  is available in car / mobile environment (e.g.
  paper display)?

11
Scope New Interaction Devices (1)

• Situation
• All networked appliances can be operated via one
  universal controller each user is carrying about
• Users can control their appliances in / out of
  the home
• Users can make multiple appliances work together
  to do complex tasks
• Application Category efficient appliance control

12
Scope New Interaction Devices (2)

• User Benefit
• Every device can be controlled in a unified
  manner
• Easy to do complex tasks using multiple devices
  (e.g. data transfer between devices / media)
• Discussion Items
• How to select necessary ones from many devices or
  functions on the network?
• How to identify the user and its position?
• What are good techniques / designs for data
  transfer between devices (e.g. pick and drop
  interface for data transfer)?
• Negotiation or priority control among the users
  who want to use the same devices simultaneously
• How to show devices and functions on the network
  to users?
• User should recognize a combination of functions
  as one abstract function?
• User should be aware which device is serving each
  function?
