FlowField and beyond: applying pressure-sensitive multi-point touchpad interaction
نویسندگان
چکیده
In this paper, we discuss a new hand-gesture-based application, FlowField, which explores the use of pressure-sensitive multipoint touchpad (multi-touch) interaction. FlowField allows participants to interact using their whole hand with a flow of circulating particles, providing visual and auditory feedback. Limitations of the raw data mapping used in FlowField motivated work on applying interpolation techniques to improve the data representation. Thus far, bicubic interpolation provides the most effective method for initial processing. We observed two factors limiting the quality of the representation: the spacing of the sensors, and the pressure-distributing property of the touchpad surface.

Lighting Control using Pressure-Sensitive Touchpads
We introduce a novel approach to control physical lighting parameters by means of a pressure-sensitive touchpad. The two-dimensional area of the touchpad is subdivided into 5 virtual sliders, each controlling the intensity of a color (red, green, blue, yellow, and white). The physical interaction methodology is modeled directly after ubiquitous mechanical sliders and dimmers which tend to be us...
متن کاملEmbodying Generative Visual Renku: An Approach to Generating Metaphors through Interactions
Generative Visual Renku (GVR) is a new form of computational visual art created by the authors. Inspired by linked verses in Japanese renku (renga) poetry, linguistic study of form and content of Chinese characters, and conceptual metaphor and blending theories from cognitive science, GVR works generate evocative compositions of graphical images through interaction between users and a computati...
متن کاملMulti-finger cursor techniques
The mouse cursor acts as a digital proxy for a finger on graphical displays. Our hands, however, have ten fingers and many degrees of freedom that we use to interact with the world. We posit that by creating graphical cursors that reflect more of the hand’s physical properties, we can allow for richer and more fluid interaction. We demonstrate this idea with three new cursors that are controlle...
متن کاملRelationship-Based Instrument Mapping of Multi-Point Data Streams Using a Trackpad Interface
Multi-point devices are rapidly becoming a practical interface choice for electronic musicians. Interfaces that generate multiple simultaneous streams of point data present a unique mapping challenge. This paper describes an analysis system for point relationships that acts as a bridge between raw streams of multi-point data and the instruments they control, using a multipoint trackpad to test ...
متن کاملWe wish to predict user frustration with computer-based tasks from the user’s patterns of application of force to a pressure-sensitive input device, the Synaptics TouchPad
An experiment was conducted to examine the utility of pressure and positional data from the Synaptics TouchPad to discriminating between baseline and problematic or frustrating user circumstances. Our special interest is in the problem of multimodal sensing and fusion of data streams from speech, haptics, and vision during acquisition of complex skills. In particular we are interested in findin...
