This paper demonstrates a pressure-sensitive depth sorting technique that extends standard two-dimensional (2D) manipulation techniques, particularly those used with multitouch or multi-point controls. Then analyzes the combination of this layering operation with a page-folding metaphor for more fluid interaction in applications requiring 2D sorting and layout.
In this paper, we propose Objects, Containers, Gestures, and Manipulations (OCGM, pronounced like Occam’s Razor) as universal foundational metaphors of Natural User Interfaces. We compare OCGM to existing paradigms using SRK behavior classification and early childhood cognitive development, and justify the “universal” and “foundational” descriptors based upon cognitive linguistics and universal grammar. If adopted, OCGM would significantly improve the conceptual understanding of NUIs by developers and designers and ultimately result in better NUI applications.
We introduce our view of the relation between symbolic gestures and manipulations in multi-touch Natural User Interfaces (NUI). We identify manipulations not gestures as the key to truly natural interfaces. Therefore we suggest that future NUI research should be more focused on designing visual workspaces and model-world interfaces that are especially appropriate for multi-touch manipulations.

Though many tabletop applications allow users to interact with the application using complex multi-touch gestures, automated tool support for testing such gestures is limited. As a result, gesture-based interactions with an application are often tested manually, which is an expensive and error prone process. In this paper, we present TouchToolkit, a tool designed to help developers automate their testing of gestures by incorporating recorded gestures into unit tests. The design of TouchToolkit was informed by a small interview study conducted to explore the challenges software developers face

Proton is a novel framework that addresses both of these problems. Using Proton, the application developer declaratively specifies each gesture as a regular expression over a stream of touch events. Proton statically analyzes the set of gestures to report conflicts, and it automatically creates gesture recognizers for the entire set. To simplify the creation of complex multitouch gestures, Proton introduces gesture tablature, a graphical notation that concisely describes the sequencing of multiple interleaved touch actions over time.

This article introduces a new interaction model called Instrumental Interaction that extends and generalizes the principles of direct manipulation. It covers existing interaction styles, including traditional WIMP interfaces, as well as new interaction styles such as two-handed input and augmented reality. It defines a design space for new interaction techniques and a set of properties for comparing them.

For document visualization, folding techniques provide a focus-plus-context approach with fairly high legibility on flat sections. To enable richer interaction, we explore the design space of multi-touch document folding. We discuss several design considerations for simple modeless gesturing and compatibility with standard Drag and Pinch gestures. We categorize gesture models along the characteristics of Symmetric/Asymmetric and Serial/Parallel, which yields three gesture models. We built a prototype document workspace application that integrates folding and standard gestures, and a system for

Delimiters are great for using gestures to overide application or OS commands. This paper investigates whether the DoubleFlip gesture is easy learn and practical to use as an effective delimter.
Many tasks in graphical user interfaces require users to interact with elements at various levels of precision. We present FingerGlass, a bimanual technique designed to improve the precision of graphical tasks on multitouch screens. It enables users to quickly navigate to different locations and across multiple scales of a scene using a single hand. The other hand can simultaneously interact with objects in the scene. Unlike traditional pan-zoom interfaces, FingerGlass retains contextual information during the interaction. We evaluated our technique in the context of precise object selection

Modern smartphones contain sophisticated sensors to monitor three-dimensional movement of the device. These sensors permit devices to recognize motion gestures— deliberate movements of the device by end-users to invoke commands. However, little is known about best-practices in motion gesture design for the mobile computing paradigm. To address this issue, we present the results of a guessability study that elicits end-user motion gestures to invoke commands on a smartphone device. We demonstrate that consensus exists among our participants on parameters of movement and on mappings of motion

This is one of three focus point presentations delivered as part of the session titled "Technology and Cyberinfrastructure," delivered on day two of the Citizen Science Toolkit Conference at the Cornell Lab of Ornithology in Ithaca, New York on June 20-23, 2007. Josh Knauer, Director of Advanced Development, Information Commons at MAYA Design, discusses the problem of "information liquidity" and how to make data available to the intended audiences and in a way that makes the data available at all times. Knauer applies the original model of the public library to the digital age and makes

These reports were delivered on day three at the conclusion of the Citizen Science Toolkit Conference at the Cornell Lab of Ornithology in Ithaca, New York on June 20-23, 2007. The reports summarize the discussions that took place in five separate breakout groups, which met periodically throughout the conference to focus on key Citizen Science themes and topics that emerged during conference presentations and plenary discussions.
