Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

Gestures for touch sensitive input devices

Proximity based systems and methods that are implemented on an electronic device are disclosed. The method includes sensing an object spaced away and in close proximity to the electronic device. The method also includes performing an action in the electronic device when an object is sensed.

Methods and systems for implementing gestures with sensing devices are disclosed. More particularly, methods and systems related to gesturing with multipoint sensing devices are disclosed.

Gesturing with a multipoint sensing device

A touch screen computer executes an application. A method of operating the touch screen computer in response to a user is provided. A virtual input device is provided on the touch screen. The virtual input device comprises a plurality of virtual keys. It is detected that a user has touched the touch screen to nominally activate at least one virtual key, and a behavior of the user with respect to touch is determined. The determined behavior is processed and a predetermined characteristic is associated with the nominally-activated at least one virtual key. A reaction to the nominal activation is determined based at least in part on a result of processing the determined behavior.

Operation of a computer with touch screen interface

This paper describes the move.me interaction prototype developed in conjunction with V2_lab in Rotterdam. move.me proposes a scenario for social interaction and the notion of social intimacy. Interaction with sensory--enhanced, soft, pliable, tactile, throw-able cushions afford new approaches to pleasure, movement and play. A somatics approach to touch and kinaesthesia provides an underlying design framework. The technology developed for move.me uses the surface of the cushion as an intelligent tactile interface. Making use of a movement analysis system called Laban Effort-Shape, we have developed a model that provides a high-level interpretation of varying qualities of touch and motion trajectory. We describe the notion of social intimacy, and how we model it through techniques in somatics and performance practice. We describe the underlying concepts of move.me and its motivations. We illustrate the structural layers of interaction and related technical detail. Finally, we discuss the related body of work in the context of evaluating our approach and conclude with plans for future work.

PillowTalk: can we afford intimacy?

In this paper, we discuss a new hand-gesture-based application, FIowField, which explores the use of pressure-sensitive multi-point touchpad (multi-touch) interaction. FIowField 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 FIowField 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.
