    • “…if designers focus only on the low- hanging fruit of functionalism or usability, the human experience with designed objects is destined to a level of mundane banality.” -- Jon Kolko Thoughts on Interaction Design IxD4D 12

    • Time Domains IxD4D 15
    • Time... • is flexible, like rubber • is both familiar and mysterious • is both concrete and fluid • has directional flow • shapes understanding • has relative meaning • is an enigma IxD4D 16
    • “Time is much weirder than we think it is.” David Eagleman Baylor College of Medicine IxD4D 17 Neuroscientist and author
    • Perception Participants are told they’re to perform a “10-minute” task. Sigh. Time flies Is it time for when you’re lunch yet? having fun! For some, task length was For others, task was terminated actually 20 minutes after just 5 minutes All were told they’d spent 10 minutes on the task. Participants who thought the task had gone by “quickly” reported it as more enjoyable. IxD4D 18

    • No limits Speed of on speed light is a for constant anything Newton Maxwell What does this mean? Einstein IxD4D
    • Special Relativity in a Nutshell • The laws of physics are the same for any two observers - no matter how fast they’re moving with respect to each other - as long as they’re moving at constant speed (not accelerating) • The speed of light is always the same - no matter your own speed - or the speed of the object that emits that light IxD4D 23
    • As a Result... • Time dilates - moving clocks slow down • Lengths compress - in the direction of motion • Mass increases - (we’ll skip this bit) IxD4D 24
    • Stationary train with “light beam” clock Clock measures time by means of a light pulse moving up and down between two mirrors. mirror I got x I got x, too light source & mirror When both the train and the observer are Observer stationary, the train passenger and an observer on the ground measure ticks of the clock and record same time interval during each cycle of the clock. IxD4D 25
    • Train traveling at near the speed of light I got x I measured y The observer sees the light pulse trace out a diagonal Observer path. The speed of light is constant, so the observer measures a greater interval during each tick of the clock and concludes the clock is running slow. The passenger sees no change from the stationary case. IxD4D 26
    • Relativity of Events y' event v y S' S' x' event y x event x S S If S = S', an event is identified as If S' is moving relative to S, an event is occurring in the same place and time, identified as occurring with different with the same spacetime coordinates: spacetime coordinates. For S: (x, y, z, t) (x, y, z, t). and for S': (x', y', z' t'). IxD4D 27

    • “Landscape architects tend to think dynamically and in space- time relationships. They are sensitive to the changing character of spaces from day to night, with seasons, and through succession. They speak not of ‘what the space is’ but of how it is experienced as one moves from place to place—the temporal experience of the place.” -- John Motloch Introduction to Landscape Design IxD4D 40
    • Designed Place IxD4D 41 Source: Introduction to Landscape Design
    • Temporal Foundations of Landscapes • Scale - from geologic (geologic uplift) to recent change (stream erosion or a fallen tree) • Sequence - natural change undergoes somewhat predictable change - cultural change is less predictable; based on differences in populations, attitudes, and perceptions • Rhythm - diurnal, seasonal, successional, weather, and climatic - nature’s purest statement of system and process - movement toward some future condition IxD4D 42
    • Landscape as Story • Sequential experience of landscape can be designed as story - each space is revealed to advantage - through serial discovery - unwrapping a temporal experience • An evolving story line choreographs the viewer’s movement through a space, accounting for - mode of transportation - character of path - designed mood of place - user behavior IxD4D 43
    • Story Lines Casual Formal IxD4D 44 Source: Introduction to Landscape Design
    • Temporal Choreography “Landscape designers can manage materials and arrangements to create interesting spatial expressions and visual relationships in all seasons, and landscapes that change with season in a rich temporal choreography.” -- John Motloch Introduction to Landscape Design IxD4D 45 Mount Diablo, California. Source: Maria Cordell
    • Thinking Temporally • Experience is inherently temporal • Design decisions have long term effects • Design-to-user dialog is ongoing • User characteristics change over time - perspective / perception - skill / responsibility - motivations - interest • Context, purpose, and meaning evolve • Time and space are inextricably linked IxD4D 46
    • Contextual Landscape user job IxD4D 47

    • Long Term Dialog “The importance of understanding the long term dialog that occurs with a product focuses around the cultural methods of use and misuse that a person engages in with this object. Indeed, long term dialog may be exponentially more important than short term usability.” -- Jon Kolko Thoughts on Interaction Design IxD4D 49
    • It’s about getting beneath the surface of functionality and behavior into the messy emotional, symbolic, mythical, habitual crap that constitutes three- quarters of normal people's existence. Stephen Taylor @anomalogue IxD4D
    • New Ethnographer’s Toolkit • Developed by Chris Khalil, Australia-based user experience architect ( • Captures key points user’s online experience • Good for studying online behavior • Ensures a realistic, natural record of participant’s life online • Recording mechanism is in same medium and context as the target design • Enables mental modeling based on authentic goals, behaviors, and motivations IxD4D 51 Source:

    • Temporally Aware Design • Design how the user • Balance casual and formal uses time • Set the tempo • Mold subjective time • Use locality • Use temporal scale • Think relativistically • Choreograph temporal • Capture layers and experience dimension IxD4D 54 Image: Maria Cordell
