What is the Organic UI ?

● Interfaces which seek to incorporate human manipulation skills into human-computer interaction.

● They more closely resemble natural human-physical and human-human interaction than traditionals.

HoloWall (1997) - About

● Camera-based interactive wall/table system.

● By using IR reflection of objects, it can distinguish multiple objects.

Sensor configuration [1]

HoloWall - Applications

Ping-pong game demo [1]

SmartSkin (2002) - About

SmartSkin [2] Sensor configuration [2]

10

SmartSkin - Prototype(1)

Top: potential field

Bottom: arms on a table and a corresponding potential field [2]

Interactive Table Prototype with SmartSkin [2]

11

SmartSkin - Interaction techniques(1)

● The simple emulation of a mouse-like interface

● Shape-based object manipulation

– The potential field created by the hand’s proximity to the table is used to move objects.

Mouse emulation by using calculated hand position (Drug) [2]

Shape-based object manipulation [2]

SmartSkin - Prototype(2)

Gesture recongnition Pad Prototype by SmartSkin [2] Gestures and corresponding

sensor values [2]

13

SmartSkin - Interaction techniques(2)

● Interaction systems by using fingers and hand gestures.

● Zooming, Scrolling, and choosing the menu commands by palm and finger position.

Application of multiple finger user interface [2]

DiamondTouch (2003) - About

DiamondTouch [3] Surface configuration [3]

15

DiamondTouch - Principles

Sensor configuration [3] Equivalent Circuit [3]

16

DiamondTouch - Merits

● Multipoint: Detects multiple, simultaneous touches.● Identifying: Detects which user is touching each point.● Debris Tolerant: Objects left on the surface do not interfere with

normal operation.● Durable: Able to withstand normal use without frequent repair

or re-calibration.● Unencumbering: No additional devices should be required for use.● Inexpensive to manufacture.

17

DiamondTouch - Demerits

● If two X and two Y coordinates are given, the system cannot tell if the intended touches are (X1, Y1) and (X2, Y2) or (X1, Y2) and (X2, Y1).

● This ambiguity is not a problem when performing simple interactions.

18

(cf.)SmartSkin v.s. DiamondTouch

Sensor configuration of SmartSkin [2]

Sensor configuration of DiamondTouch [3]

● SmartSkin: Being able to detect many points (includes finger points and palms).

● DiamondTouch: Being able to identify each users.

PreSense (2006) - AboutⅡ

PreSense [4]Ⅱ Sensor configuration [4]

20

PreSense - PrinciplesⅡ

The graph of multi-level button operation and corresponding pressure value traces [4]

21

PreSense - ApplicationsⅡ

Sample applications [4]

● Scrolling by sliding a finger on a touchpad and zooming (in and out) by bi-directional finger pressure.

● Only scrolling but speed is controlled by bi-directional finger pressure

22

Today's Theme - (3)

● Know what is the Organic UI (OUI).● Study the examples of OUI.● Understand the research issues of OUI.● Think what is the future of interaction”. “

23

Research issues of organic UIs

● There are three Research issues.

– Interaction techniques for Organic UIs

– Stone(Tool) v.s. skin

– Other modalities for interaction

24

Interaction techniques for Organic UIs

● GUI v.s. OUIs(Organic UIs)

● Some new techniques

– As-Rigid-As-Possible Shape Manipulation [5]

GUI OUIs

Interface Mouse (MultiTouch)

Interaction tech(first time) Point at objects Zooming

Interaction tech(next time)

Pop-up menus / scrollbars NONE!!!

25

As-Rigid-As-Possible Shape Manipulation [5]

● Interactive system that lets a user move and deform a two-dimensional shape

● With a multiple-point input device, even beginners can easily move, rotate, and deform shapes at will.

Sample applications [6]

26

Stone(Tool) v.s. skin

● TUIs(Tangible UIs) v.s. OUIs(Organic UIs)

TUIs OUIs

Action Physical manipulation Directlyinteraction

Compatibillity to application Domain-specific Less application-oriented

Being compared to real world Physical instruments Direct contact

Conclusion Logical, manipulation-oriented Emotional, communication-oriented

27

Other modalities for interaction

● Now : mainly hands● Should be able to use other parts.

– Eye gaze, Blowing, ...● Controllable, Conveying emotion

● BYU-BYU-View System [7]

– Adds air movement in the interaction.

– Delivering information directly to the skin.

28

29

What is the future of interation” ?“

● “interaction”– Now : between a human and a conputer

– Next : between the real (physical) world and computers● Controlling more physical experience (illumination, air, temperature,

humidity, energy)

● ex) Stabilizing room condition by reacting to human gesture.● “Future interactive systems may more seamlessly interact with and

control our physical environments.”
