One of the main benefits of model-driven development of userinterfaces (UIs) is the increase in efficiency and consistency when developing multiple variants of a UI. For instance, multiple UIs for different target users, platforms, devices, or for whole product families can be generated from the same abstract models. However, purely generated UIs are not always sufficient as there is often need for customizing the individual UI variants, e.g., due to usability issues or specific customer *** this paper we present a model-driven approach for the development of UI families with systematic support for customizations. The approach supports customizing all aspects of a UI (UI elements, screens, navigation, etc.) and storing the customizations in specific models. As a result, a UI family can be evolved more efficiently because individual UI variants can be re-generated (after some changes have been applied to the family) without losing any previously made customizations. We demonstrate this by thirty highly customized real-world products from a commercial family of web information systems called HIS-GX/QIS.

Spatial augmented reality (SAR) makes possible the projection of virtual environments into the real world. In this demo, we propose to demonstrate our SAR tools dedicated to the creation of physical drawings. From the most simple tools: the projection on virtual guidelines enabling to trace lines and curves to more advanced techniques enabling stereoscopic drawing through the projection of a 3D scene. This demo presents how we can use computer graphics tools to ease the drawing, and how it will enable new kinds of physical drawings.

Touch-screens are becoming increasingly ubiquitous. They have great appeal due to their capabilities to support new forms of human interaction, including their abilities to interpret rich gestural inputs, render flexible userinterfaces and enable multi-user interactions. However, the technology creates new challenges and barriers for users with limited levels of vision and motor abilities. The PhD work described in this paper proposes a technique combining Shared user Models (SUM) and adaptive interfaces to improve the accessibility of touch-screen devices for people with low levels of vision and motor ability. SUM, built from an individual's interaction data across multiple applications and devices, is used to infer new knowledge of their abilities and characteristics, without the need for continuous calibration exercises or user configurations. This approach has been realized through the development of an open source software framework to support the creation of applications that make use of SUM to adapt interfaces that match the needs of individual users.

We propose a novel hand-gesture recognition method based on mechanomyograms (MMGs). Skeletal muscles generate sounds specific to their activity. By recording and analyzing these sounds, MMGs provide means to evaluate the activity. Previous research revealed that specific motions produce specific sounds enabling human motion to be classified based on MMGs. In that research, microphones and accelerometers are often used to record muscle sounds. However, environmental conditions such as noise and human motion itself easily overwhelm such sensors. In this paper, we propose to use piezoelectric-based sensing of MMGs to improve robustness from environmental conditions. The preliminary evaluation shows this method is capable of classifying several hand gestures correctly with high accuracy under certain situations.

The Web is far less usable and accessible for the users with visual impairments than it is for the sighted people. Web automation has the potential to bridge the divide between the ways visually impaired people and sighted people access the Web, and enable visually impaired users to breeze through Web browsing tasks that beforehand were slow, hard, or even impossible to achieve. Typical automation interfaces require that the user record a macro, a useful sequence of browsing steps, so that these steps can be re-played in the future. In this paper, I present a high-level overview of an approach that enables users to find quickly relevant information on the webpage, and automate browsing without recording macros. This approach is potentially useful both for visually impaired, and sighted users.

We propose TouchCast, which is an on-line platform for the creating and sharing of tactile content based on Tactile Copy & Paste. user-Generated Tactile Content refers to tactile content that is created, shared and appreciated by general Internet users. TouchCast enables users to create tactile content by applying tactile textures to existing on-line content (e.g., illustrations) and to share the created content over the network. Applied textures are scanned from real objects as audio signals, and we call this technique Tactile Copy & Paste. In this study, we implement the system as a Web browser add-on to create user Generated Tactile Content.

We present Waken, an application-independent system that recognizes UI components and activities from screen captured videos, without any prior knowledge of that application. Waken can identify the cursors, icons, menus, and tooltips that an application contains, and when those items are used. Waken uses frame differencing to identify occurrences of behaviors that are common across graphical userinterfaces. Candidate templates are built, and then other occurrences of those templates are identified using a multi-phase algorithm. An evaluation demonstrates that the system can successfully reconstruct many aspects of a UI without any prior application-dependant knowledge. To showcase the design opportunities that are introduced by having this additional meta-data, we present the Waken Video Player, which allows users to directly interact with UI components that are displayed in the video.

Smartphones are convenient, but their small screens make searching, clicking, and reading awkward. Thus, perusing product reviews on a smartphone is difficult. In response, we introduce REVMINER-a novel smartphone interface that utilizes Natural Language Processing techniques to analyze and navigate reviews. REVMINER was run over 300K Yelp restaurant reviews extracting attribute-value pairs, where attributes represent restaurant attributes such as sushi and service, and values represent opinions about the attributes such as fresh or fast. These pairs were aggregated and used to: 1) answer queries such as "cheap Indian food", 2) concisely present information about each restaurant, and 3) identify similar restaurants. Our user studies demonstrate that on a smartphone, participants preferred REVMINER's interface to tag clouds and color bars, and that they preferred REVMINER's results to Yelp's, particularly for conjunctive queries (e.g., "great food and huge portions"). Demonstrations of REVMINER are available at revminer . com.

Review Explorer is an interface that utilizes categorized information to help users to explore a huge amount of online reviews more easily. It allows users to sort entities (e.g. restaurants, products) based on their ratings of different aspects (e.g. food for restaurants) and highlight sentences that are related to the selected aspect. Existing interfaces that summarize the aspect information in reviews suffer from the erroneous predictions made by the systems. To solve this problem, Review Explorer performs a real-time aspect sentiment analysis when a reviewer is composing a review and provides an interface for the reviewer to easily correct the errors. This novel design motivates reviewers to provide corrected aspect sentiment labels, which enables our system to provide more accurate information than existing interfaces.
