What is a diamondtouch table

What is a DiamondTouch Table?

  • Looks and feels like a table

  • A Multi-User Interface

    • Developed at Mitsubishi Electric Research Laboratories (MERL) in 2001

    • Size of Entire Table (36 x 24in / 91.4 x 60.96cm)

How does it work

1cm

How Does it Work?

  • Table surface is an array of antennas

  • Capacitive Circuit:

    • table  user  receiver pad  table  pc

Questions

Questions

  • What are the quirks / limitations of the DiamondTouch table?

  • Possible applications?

Interact 2003


Tetratetris

TetraTetris

  • Multi-user

  • Simultaneous input

  • Hand-gestures

  • Intuitive

  • Fun

  • Design Goals:

Interact 2003


Tetratetris rules

TetraTetris: Rules

  • Based off Tetris

  • Orig. Designed for 4

  • Touch-take

  • Objective: Symmetrical compounds

Interact 2003


Implementation issues

Implementation Issues

  • Finicky electronics

    • Electrical interference

  • Row / col matching

    • Table does not match rows with columns

    • Does NOT distinguish what pair of corners is touched

    • Our solution: “The bounding box”

Interact 2003


Bounding box cont

Box Width Increase Turn Right

Box Height Increase Turn Left

Bounding Box, Cont.

  • Takes outer-most rows and columns

  • Can be used like a ‘lasso’

  • Rotational ambiguity

Interact 2003


Observations

Observations

  • No physical separation of input from output

  • Fast manipulation of large regions

  • Support for multiple, simultaneous users

Interact 2003


Challenges

Challenges

  • Size of touch surface

    • 33 x 20 inches (84 x 51 cm)

  • Precision control

    • Table resolution (160x96)

    • After weighted interpolation (2560x1536)

    • Finger >> pixel

  • Lack of ability to display output

    • 7 minute solution: lots of duct tape

Interact 2003


Usefulness

Usefulness

  • Direct touch and drag

  • Collaborative use of the same application

  • Manipulating several objects using the ‘bounding-box’

Interact 2003


Areas for improvement

Areas for Improvement

  • Precision control / Rotational ambiguity

  • Cost of setup

  • Electrical interference

Interact 2003


The future

The Future?

  • Current improvements from MERL

    • Less electrical interference

    • Now fits standard 4:3 aspect ratio (orig. 5:3)

    • Maturing Software Development Kit

  • Possible applications

    • Cooperative architecture design

    • Collaborative musical composition

    • Coordinated disaster relief planning
