Gestural interfaces allow complex manipulative interactions that are hardly manageable using traditional event handlers. Indeed, such kind of interaction has longer duration in time than that carried out in form-based userinterfaces, and often it is important to provide users with intermediate feedback during the gesture performance. Therefore, the gesture specification code is a mixture of the recognition logic and the feedback definition. This makes it difficult 1) to write maintainable code and 2) reuse the gesture definition in different applications. To overcome these kinds of limitations, the research community has considered declarative approaches for the specification of gesture temporal evolution. In this paper, we discuss the creation of gestural interfaces using GestIT, a framework that allows declarative and compositional definition of gestures for different recognition platforms (e.g. multitouch and full-body), through a set of examples and the comparison with existing approaches.

E-Block is a tangible programming tool for children aged 5 to 9 which gives children a preliminary understanding of programming. Children can write programs to play a maze game by placing the programming blocks in E-Block. The two stages in a general programming process: programming and running are all embodied in E-Block. We realized E-Block by wireless and infrared technology and gave it feedbacks on both screen and programming blocks. The result of a preliminary user study proved that E-Block is attractive to children and easy to learn and use.

Embroidery is a creative manual activity practiced by many people for a living. Such a craft demands skill and knowledge, and as it is sometimes complicated and delicate, it can be difficult for beginners to learn. We propose a system, named the Needle userinterface, which enables sewers to record and share their needlework, and receive feedback. In particular, this system can detect the position and orientation of a needle being inserted into and removed from a textile. Moreover, this system can give visual, auditory, and haptic feedback to users in real time for directing their actions appropriately. In this paper, we describe the system design, the input system, and the feedback delivery mechanism.

This study presents an interactive configuration tool that assists non-expert users to design specific navigation route for mobile robot in an indoor environment. The user places small active markers, called pebbles, on the floor along the desired route in order to guide the robot to the destination. The active markers establish a navigation network by communicating each other with IR beacon and the robot follows the markers to reach the designated goal. During the installation, a user can get effective feedback from LED indicators and voice prompts, so that the user can immediately understand if the navigation route is appropriately configured as expected. With this tool a novice user may easily customize a mobile robot for various indoor tasks.

We present an unobtrusive multimodal interface for smart objects (MISO) in an everyday indoor environment. MISO uses pointing for object selection and context-sensitive arm gestures for object control. Finger snaps are used to confirm object selections and to aid with gesture segmentation. Audio feedback is provided during the interaction. The use of a Kinect depth camera allows for a compact system and robustness in varying environments and lighting conditions at low cost.

We present a new tongue detection system called SITA, which comprises only a Kinect device and conventional laptop computer. In contrast with other tongue-based devices, the SITA system does not require the subject to wear a device. This avoids the issue of oral hygiene and removes the risk of swallowing a device inserted in the mouth. In this paper, we introduce the SITA system and an application. To evaluate the system, a user test was conducted. The results indicate that the system could detect the tongue position in real time. Moreover, there are possibilities of training the tongue with this system.

Spatial augmented reality (SAR) promises the integration of digital information in the real (physical) world through projection. In this doctoral symposium paper, I propose different tools to improve speed or ease the drawing by projecting photos, virtual construction lines and interactive 3D scenes. After describing the tools, I explain some future challenges to explore such as the creation of tools which helps to create drawings that are "difficult" to achieve for a human being, but easy to do by a computer. Furthermore, I propose some insights for the creation of digital games and programs which can take full advantages of physical drawings.

Interactive behaviors in GUIs are often described in terms of states, transitions, and constraints, where the constraints only hold in certain states. These constraints maintain relationships among objects, control the graphical layout, and link the userinterface to an underlying data model. However, no existing Web implementation technology provides direct support for all of these, so the code for maintaining constraints and tracking state may end up spread across multiple languages and libraries. In this paper we describe ConstraintJS, a system that integrates constraints and finite-state machines (FSMs) with Web languages. A key role for the FSMs is to enable and disable constraints based on the interface's current mode, making it possible to write constraints that sometimes hold. We illustrate that constraints combined with FSMs can be a clearer way of defining many interactive behaviors with a series of examples.

Autonomous robots and vehicles can perform tasks that are unsafe or undesirable for humans to do themselves, such as investigate safety in nuclear reactors or assess structural damage to a building or bridge after an earthquake. In addition, improvements in autonomous modes of such vehicles are making it easier for minimally-trained individuals to operate the vehicles. As the autonomous capabilities advance, the user's role shifts from a direct teleoperator to a supervisory control role. Since the human operator is often better suited to make decisions in uncertain situations, it is important for the human operator to have awareness of the environment in which the vehicle is operating in order to prevent collisions and damage to the vehicle as well as the structures and people in the vicinity. In this paper, we present the Collision and Obstacle Detection and Alerting (CODA) display, a novel interface to enable safe piloting of a Micro
