Exploring Tangible User Interfaces: Bridging Physical and Digital Worlds

This course by Helge Hüttenrauch at KTH focuses on Tangible User Interfaces (TUI) and their evolution, emphasizing the integration of physical objects with digital interactions. Students will engage with concepts such as mediaBlocks, ambient rooms, and non-intrusive RFID tagging, exploring the implications of these technologies on human-machine interaction. Discussion topics also include privacy, presence awareness, and the evolving role of interfaces in communication, culminating in a deeper understanding of the future of design in HCI.

  1. Touch’n Go — Tangible User Interfaces UC course, Kista/Stockholm 00-04-10 Helge Hütttenrauch hehu@nada.kth.se Helge Hüttenrauch Human Machine Interaction Graduate School

  2. Things to come • based upon... • short summaries • notable, questionable • reflections & research agenda including robots...  Helge Hüttenrauch Human Machine Interaction Graduate School

  3. Order of appearance • Tangible Bits… Ishii, Ullmer [MIT] • mediaBlocks • Bridging Physical… Want et.al. [X-PARC] • Tangible Progress… Singer et.al. • Pick and Drop… Rekimoto [Sony] • see course mail for details Helge Hüttenrauch Human Machine Interaction Graduate School

  4. Tangible Bits • ”tangible” Def: 1. Possible to be treated as fact, real or concrete; 2. Possible to understand or realize; 3. Law: that can be valued monetarily • [The American Heritage Dictionary of the English Language, ‘96] • Richness of physical objects • Goals: TUI, Bits-Atoms coupling, Ambient M • evolution: • metaDESK, transBOARD, ambientROOM • Optical metaphors are suited • from ”painted” to ”tangible bits” Helge Hüttenrauch Human Machine Interaction Graduate School

  5. mediaBlocks • For containment, transport, manipulation • wooden blocks with electronic tags, i.e. • mechanism of physical reference and exchange • UI: Screen+bricks+3D+jogdialbutton • questions: editing? Mixed media? Open de- • facto Document standards? (unwanted by • Industry…(?); ”I lost my thesis brick…”, SAFETY? Helge Hüttenrauch Human Machine Interaction Graduate School

  6. Bridging Worlds • Non-intrusive RFID tags in the office • needs: mobility, cheap, easy to deploy, • human-like range, non-screen, non-hands, • low-power • issues: tag-manic (who administers this…?) • invisible tagging: what’s tagged? User • control or automatic default action? • Interference? Helge Hüttenrauch Human Machine Interaction Graduate School

  7. Tangible Audio Spaces • Audio-only media space in communication • 4 Ifs for Somewire: Faders, Vizwire, • Thunderwire, ToonTown • physical representation of people and comic • representation on the screen • issues: privacy and representation, • presence awareness, social implications • audio space: GUIless, no audio controls, • awareness of other users’ presence; Helge Hüttenrauch Human Machine Interaction Graduate School

  8. Pick and Drop • multi-computer DMI chaos is a fact • exchange important, but inconvenient • pens with IDs and networked mechanism • seamless with today's usage • physical better than symbolic referencing • info-exchange below file-level, need for • non-technical solutions • ”C-pen” Helge Hüttenrauch Human Machine Interaction Graduate School

  9. Reflections • abstract digital on the move into graspable • things; (and vice versa); where’s the • balance? • We will be totally online & UCed - HOW? • Representation, manipulation, interaction, • and communication will change; • many unsolved details not captured yet, e.g. • privacy, security, administration, usage • 1st products out Helge Hüttenrauch Human Machine Interaction Graduate School

  10. Reflections II • what are the parallel change for traditional • means? Altered or substituted? • Where’s this NEW HCI for this field? The • models, the guidelines, the methods, the • usability testing, the textbooks,... • where and how does delegation to soft- or • real ”Bots” come in (a.k.a. agents, robots…) • I believe: Bridging physical and virtual • worlds will earn us our pay in the next 5 • years!
