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.
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.
Despite a long history of using participatory methods to enable public engagement with issues of societal importance, interactive displays have only recently been explored for this purpose. In this paper, we evaluate a tabletop game called Futura, which was designed to engage the public with issues of sustainability. Our design is grounded in prior research on public displays, serious games, and computer supported collaborative learning. We suggest that a role-based, persistent simulation style game implemented on a multi-touch tabletop affords unique opportunities for a walk-up-and-play style

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
