Last Year… [Poupyrev and Maruyama, UIST 2003]

Slide 3

Our Goals: Support huge touch-delicate presentations. Bolster different synchronous clients.

Slide 4

Our Goals: Support vast touch-touchy showcases. Bolster various concurrent clients. Our Solution: Haptic Pen -Feedback not attached to show -Individualized input -Pressure Sensitivity -Non-Contact Location information -Low-cost

Slide 5

Prototype Implementation External control board and power supply. RS-232 interface to PC. Parts in model cost ~$10. Precious stone Touch Interface [Dietz, UIST\'01] - DT is a Multi-client front-anticipated touch table - Haptic Pen is area innovation freethinker

Tactile Styli Anoto Pen (by Logitech) unusual mass engine SensAble PHANTOM grounded intelligent drive

Slide 7

Tactile Styli Anoto Pen (by Logitech) whimsical mass engine SensAble PHANTOM grounded intelligent compel

Slide 8

Tactile Styli Buzzing is adequate for collaboration criticism. Drive/High-Frequency strengths important to recreate snaps are unrealistic. Horizontal strengths are unnatural. Anoto Pen (by Logitech) unpredictable mass engine

Longitudinal Force

Slide 12

Longitudinal Force along same constrain vector

Slide 13

Lateral Force horizontal compel is unnatural

Slide 15

Solenoid Actions

Slide 16

Haptic Behaviors Haptic Behavior – a mapping of solenoid activities to the states and moves of a communication. Essential Click:

Slide 17

Haptic Behaviors for Buttons No Click – No criticism, basically for control examination Light Click – Light limit, frail input ("ballpoint pen") Basic Click – Medium edge, medium input Hard Click – High edge, solid input ("punch device") Buzz – Fixed quality buzz when squeezed ("blunder") Force Buzz – Proportional quality buzz ("dental practitioner") Two-Click – Two level catch ("camera shade") Buzz-Click – Two level catch ("test and affirm")

Slide 18

Interaction Concepts Multi-work catches Input mistake input Two-Click for mapping stylus single & double tap Stiff affirmation catches Toggle switches – Light Click on, Hard Click off Data Peeking – firmness driven by shrouded variable Tactile Alerts – Continuous contact with client Targeting – humming driven by nearness, district, or bearing.

Slide 19

Off the Screen Haptic Pen + Anoto Tracking = Drawable Tactile Interfaces 3D following permits material criticism on any enrolled surface.

Slide 20

Future Directions Develop more vigorous and minimized models and investigate a remote execution Explore errands which have the best potential for development in execution and client fulfillment Develop equipment and programming advancements for multi-client material applications
