Single-handed interaction techniques for multiple pressure-sensitive strips

Abstract

We present a set of interaction techniques that make novel use of a small pressure-sensitive pad to allow one-handed direct control of a large number of parameters. The surface of the pressure-sensitive pad is logically divided into four linear strips which simulate traditional interaction metaphors and the functions of which may be modified dynamically under software control. No homing of the hand or fingers in needed once the fingers are placed above their corresponding strips. We show how the number of strips on the pad can be virtually extended from four to fourteen by detecting contact pressure differences and dual-finger motions. Due to the compact size of the device and the method of interaction, which does not rely on on-screen widgets or the 2D navigation of a cursor, the versatile input system may be used in applications, where it is advantageous to minimize the amount of visual feedback required for interaction.

Augmenting the mouse with pressure sensitive input

“…Blasko and Feiner [3] proposed multiple pressure-sensitive strips by segmenting a touchpad into different regions. They show that pressure-sensitive strips do not require visual feedback and users can control a large number of widgets using their fingers.…”

“…Although, pressure based input is featured in many digitizers and TabletPCs and has been widely studied [3,11,15,16], little is known about the limitations to pressure based input using a mouse. This lack of knowledge may explain why the pressure buttons available on the MightyMouse™ do not supply continuous pressure values and operate similar to a two-state button.…”

Multi-touch techniques for exploring large-scale 3D astrophysical simulations

“…Esenther et al [15,16] then developed the DiamondTouch SDK that supports multi-user and multi-touch interactions simultaneously on the same physical surface, which enables effective collaborative work among groups of people. Rekimoto [39] introduced a new sensor architecture called SmartSkin that makes interactive surfaces sensitive to both human hand and finger gestures, while Blaskó and Feiner [5] presented novel uses of a pressure-sensitive pad that simulates sliders and spinning wheels with their multi-strip design. Han [22] presented a novel design for multi-touch sensing using frustrated total internal reflection.…”

A Pressure-Sensing Mouse Button for Multilevel Click and Drag

“…Blaskó et al developed the "Pressure-Sensitive Strips" that allows one-handed direct control of a large number of parameters by detecting contact pressure differences of user's fingers [6].…”
