1. Johan Mattsson johanm@dsv.su.se Interaction Through Spells Embodied, collaborative composition of ubiquitous services

2. Interaction Trough Spells Johan Mattsson Co-located collaborative & ubiquitous computing  Transparent sharing of computation  Adaptable environment, providing a shared opportunities of control  Wireless devices, provides easily connections between any services  Generic networked services, possibly residing and accessed anywhere

3. Interaction Trough Spells Johan Mattsson Lost in a collaborative interactive work session?  Awareness of shared activities, what are we trying to achieve with all ongoing possible activities  Transparency between social interaction and computer interaction  Democracy, why did this happened? -I couldn't share my opinion on it

4. Interaction Trough Spells Johan Mattsson Research questions  Can we make it easier and more intuitive, from a group perspective to configure interactive work environment The initial setup for a project session Temporal adaptations within a session  Transparency, how to support: Collective view on how the environment is used Fair interpretations on co-workers intentions with their actions  How can we empower real-world actions to refine collaborative work and experiences?

5. Interaction Trough Spells Johan Mattsson Approach  Exploring ways of adjusting and augment ‘social protocol’ to offer intuitive interaction alternatives for interactive spaces  Designing and experiment with interaction techniques aiming to provide expressions and meaning to: Co-located users Trigger computer interactions

6. Interaction Trough Spells Johan Mattsson Spells  Embodied traces expressing the configurations of seamless ubiquitous devices and services Publicly shared expressive interaction Tangible interaction as intuitive symbolic expressions  “Embodied Interaction is the creation, manipulation, and sharing of meaning through engaged interaction with artifacts.” [Dourish]

7. Interaction Trough Spells Johan Mattsson Interacting trough spells  Empowers embodied user behaviour such as: Pointing Touching Waving Spatially place an item in place …  Map of the activities and related services and devices provided as a trace of socially and tangible experiences  Implicit real-world actions overloaded to executive and predictive explicit interaction

8. Interaction Trough Spells Johan Mattsson Where spells support collaborative post desktop computation  Service selection, makes the environment announce and present public services and application related to any physical property  Shared Guidance and information, items in the real world are able to share knowledge or usage instructions  Transformation and connection, …

9. Interaction Trough Spells Johan Mattsson Transformation and connection  Transparent moving and adapting of computation Transparent transferring computation and data: moving or copying information between devices Transferring control, how we act to redirect I/O streams, e.g. how we:  Express a change target for input  Announce a change of responsibility or source user Transfer and transforming behaviours over distances and modalities

10. Interaction Trough Spells Johan Mattsson Hypotheses  Predictable/accountable acting will affect the involvement and engagement positively  The supported acting are intuitive to handle and co-workers made fair predictions on the acting

11. Interaction Trough Spells Johan Mattsson Prototypes  iwand’s  Magic Bowl  (The old knob)

12. Interaction Trough Spells Johan Mattsson iwand concept: transferring computation example  1’st selects and fetch the sound stream from the phone  2’nd moving the incoming sound to the common speaker system

13. Interaction Trough Spells Johan Mattsson iwand, 2’nd iteration  Creates connections between real-world entities by pointing  Enchantment targets applied on relevant entities  A laser enabled PDA triggers the targets to reply wirelessly with parameters that forms the spell content

14. Interaction Trough Spells Johan Mattsson Magic Bowl  Magic objects are with attached RFID  The bowls are capable of identifying several tagged object simultaneously  Magic items “opens a secret door to” certain functionality, project data, room settings, etc.

15. Interaction Trough Spells Johan Mattsson Where is the magic?  Expressive actions enchants/executes changes in the environment  The magic spells are supported by enchanted tangible tools  Empowered user behaviour appeals to fictional magic: Pointing with a magic wand to remotely cast a spell Waving or touching a wand over something to bless or enchant it Put an magic item in the right place to open a secret door
