Multimodal, Crossmedia, Multi Platform Multimodal, Crossmedia, Multi Platform Presentation Transcript

  • UXD minor theme ‘Multimodal, Crossmedia and Multi-Platform INPUT MODALITIES
  • Theme program March 23: ‘Input modalities’ (Hans), workshop and assignment kick-off March 30: ‘Output modalities’ (Rolf) and assignment progress April 6: Workshop with Pieter Jongerius (Fabrique) April 13: No class, Easter April 20: Final presentations assignment
  • Theme in the scheme of things Media, modalities and platforms provide us the nuts and bolts of the user experience. The quality of the user experience is determined by our ability to utilize the media, modalities and platforms at our disposal. View slide
  • Crossmedia ‘Crossmedia (also known as Cross-Media, Cross- Media Entertainment, Cross-Media Communication) is a media property owned, service, story or experience distributed across media platforms using a variety of media forms.’ http://en.wikipedia.org/wiki/Crossmedia View slide
  • Multi-platform ‘In computing, cross-platform (also known as multi-platform) is a term used to refer to computer software or computing methods and concepts that are implemented and inter- operate on multiple computer platforms.’ http://en.wikipedia.org/wiki/Multiplatform
  • Multimodal ‘Multimodal interaction provides the user with multiple modes of interfacing with a system beyond the traditional keyboard and mouse input/output.’ http://en.wikipedia.org/wiki/Multimodal_interaction
  • Modality ‘A modality is a path of communication between the human and the computer.’ http://en.wikipedia.org/wiki/Modality_(human-computer_interaction)
  • Input modalities and output modalities ‘In human-computer interaction, a modality is the general class of:  a sense through which the human can receive the output of the computer (for example, vision modality)  a sensor or device through which the computer can receive the input from the human’ http://en.wikipedia.org/wiki/Modality_(human-computer_interaction)
  • Output modalities (computer-to-human) ‘Any human sense can be translated to a modality:  Major modalities  Seeing or vision modality  Hearing or audition modality  Haptic modalities  Touch, tactile or tactition modality — the sense of pressure  Proprioception modality — the perception of body awareness  Other modalities  Taste or gustation modality  Smell or olfaction modality  Thermoception modality — the sense of heat and the cold  Nociception modality — the perception of pain  Equilibrioception modality — the perception of balance’ http://en.wikipedia.org/wiki/Modality_(human-computer_interaction)
  • Input modalities (human-to-computer) An input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system (such as a computer). http://en.wikipedia.org/wiki/Input_devices
  • Pointing devices Ivan Sutherland (MIT) demoing Sketchpad (1962) (introduced by Alan Kay in 1987)
  • Pointing devices ‘Pointing devices are input devices used to specify a position in space.  Direct/indirect  Absolute/relative’ http://en.wikipedia.org/wiki/Input_devices
  • Fitts’ law ‘The time it takes to move from a starting position to a final target is determined by the distance to the target and the size of the object.’ (Saffer, 2007)
  • Pointing devices And you can point at more than merely pixels on a screen…
  • Alphanumeric input: keyboards
  • Alphanumeric input: keyboards
  • Alphanumeric input: keyboards
  • Alphanumeric input: speech recognition Speaker dependent/independent Discrete-word/connected-word input Limited/large vocabulary
  • Alphanumeric input: handwriting recognition ‘Recognition’ patents as early as 1914 ‘Electronic ink’ and recognition in Vista http://www.freepatentsonline .com/1117184.pdf
  • Pen Computing ‘The return of the pen’ Switching modes: ‘pointing’ vs. ‘ink’
  • Tap is the New Click quot;One of the things our grandchildren will find quaintest about us is that we distinguish the digital from the real.“ William Gibson - from: Saffer (2009)
  • Ubiquitous computing ‘Ubiquitous computing (ubicomp) is a post- desktop model of human-computer interaction in which information processing has been thoroughly integrated into everyday objects and activities.’ http://en.wikipedia.org/wiki/Ubiquitous_computing
  • Wearable computing ‘Wearable computers are computers that are worn on the body.’ http://en.wikipedia.org/wiki/Wearable_computer
  • Tangible user interfaces Hiroshi Ishii (MIT)
  • Sketching Mobile Experiences Workshop in ‘Design This!’
  • Gestural Interfaces Touchscreen vs. Free-form
  • Ergonomics of Interactive Gestures quot;Hands are underrated. Eyes are in charge, mind gets all the study, and heads do all the talking. Hands type letters, push mice around, and grip steering wheels, so they are not idle, just underemployed.quot; —Malcolm McCullough, Abstracting Craft (from: Saffer, 2009)
  • Ergonomics of Interactive Gestures  Limitations due to anatomy, physiology and mechanics of the human body (kinesiology)  Left-handedness (7-10%)  Fingernails  Screen Coverage
  • Designing Touch Targets No smaller than 1x1cm in an ideal world In a not so ideal world: Iceberg Tips Adaptive Targets
  • Designing Touch Targets But even spaciously sized targets can be tricky…
  • Patterns for Touchscreens and Interactive Surfaces Tap to open/activate
  • Patterns for Touchscreens and Interactive Surfaces Tap to select
  • Patterns for Touchscreens and Interactive Surfaces Drag to move object
  • Patterns for Touchscreens and Interactive Surfaces Slide to scroll
  • Patterns for Touchscreens and Interactive Surfaces Spin to scroll
  • Patterns for Touchscreens and Interactive Surfaces Pinch to shrink and spread to enlarge
  • Patterns for Free-Form Interactive Gestures Proximity activates/deactivates
  • Patterns for Free-Form Interactive Gestures Point to select/activate
  • Patterns for Free-Form Interactive Gestures Rotate to change state
  • Patterns for Free-Form Interactive Gestures Shake to change
  • Patterns for Free-Form Interactive Gestures Tilt to move

  • Theme assignment
  • Today’s workshop assignment  Work together in teams of 2-3 students on one input device  Each team will be investigating the following:  What’s the typical application of this device?  What are typical patterns applied with this device?  How can this device connect to a computer?  What driver or other software is available for this device?  How can I adjust the parameters of this device?  How can I create application prototypes with this device?  Build a simple demonstrator for the device, using your laptop computer  Analyze the user experience with your demonstrator  Present your demonstrator at the end of the afternoon  Document your findings in a pdf document  Link the document to a post on your blog
  • Today’s workshop assignment Available devices  Touch screen (2)  Wii mote (4)  Xbox USB controller (2)  Wacom (3)  Web cam (5)  SpaceNavigator (1)  Presenter (3)  Smartboard (1)  iPhone (?)
