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.

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

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 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)

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

Input modalities (human-to-comp.)

Pointing devicesIvan 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 devicesAnd you can point at more than merely

pixels on a screen…

Pen Computing

Switching modes: ‘pointing’ vs. ‘ink’

Tap is the New Click"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/Natural user interfaces

Gestural InterfacesTouchscreen vs. Free-form

Ergonomics of Interactive Gestures

"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."

—Malcolm McCullough, Abstracting Craft(from: Saffer, 2009)
