We present a survey of design issues for developing effective free-space three-dimensional (3D) user interfaces. Our is based upon previous work in 3D interaction, our experience interfaces, and informal observations test users. illustrate using examples drawn from instances interfaces.For example, first issue suggests that users have difficulty understanding space. offer set strategies which may help to better perceive virtual environment, including the use spatial references, relative...

This research explores distributed sensing techniques for mobile devices using synchronous gestures. These are patterns of activity, contributed by multiple users (or one user with devices), which take on a new meaning when they occur together in time, or specific sequence time. To explore this area inquiry, work uses tablet computers augmented touch sensors and two-axis linear accelerometers (tilt sensors). The connected via an 802.11 wireless network synchronize their time-stamped sensor...

We describe techniques for direct pen+touch input. observe people's manual behaviors with physical paper and notebooks. These serve as the foundation a prototype Microsoft Surface application, centered on note-taking scrapbooking of materials. Based our explorations we advocate division labor between pen touch: writes, touch manipulates, combination + yields new tools. This articulates how system interprets unimodal pen, touch, multimodal inputs, respectively. For example, user can hold...

Stitching is a new interaction technique that allows users to combine pen-operated mobile devices with wireless networking by using pen gestures span multiple displays. To stitch, user starts moving the on one screen, crosses over bezel, and finishes stroke screen of nearby device. Properties each portion are observed participating devices, synchronized via network communication, recognized as unitary act performed user, thus binding together devices. We identify general requirements...

GroupTogether is a system that explores cross-device interaction using two sociological constructs. First, F-formations concern the distance and relative body orientation among multiple users, which indicate when how people position themselves as group. Second, micro-mobility describes orient tilt devices towards one another to promote fine-grained sharing during co-present collaboration. We sense these constructs using: (a) pair of overhead Kinect depth cameras small groups people, (b)...

The Task Gallery is a window manager that uses interactive 3D graphics to provide direct support for task management and document comparison, lacking from many systems implementing the desktop metaphor. User tasks appear as artwork hung on walls of virtual art gallery, with selected stage. Multiple documents can be displayed side-by-side using space uniform intuitive scaling. hosts any Windows application, novel redirection mechanism routes input output between environment unmodified 2D...

We discuss a two-handed user interface designed to support three-dimesional neurosurgical visualization. By itself, this system is “point design,” an example of advanced technique. In work, we argue that in order understand why interaction techniques do or not and suggest possibilities for new techniques, it important move beyond point design introduce careful scientific measurement human behavioral principles. particular, the common-sense viewpoint “two hands save time by working parallel”...

Inking and gesturing are two central tasks in pen-based user interfaces. Switching between modes for entry of uninterpreted ink gestures is required by many Without an appropriate mode switching technique, interactions such situations may be inefficient cumbersome. In this paper, we investigate five techniques gesture pen interfaces, including a pen-pressure based technique that allows implicit transition. A quantitative experimental study was conducted to evaluate the performance these...

We present a quantitative analysis of delimiters for pen gestures. A delimiter is "something different" in the input stream that computer can use to determine structure phrases. study four techniques delimiting selection-action gesture phrase consisting lasso selection plus marking-menu-based command activation. Pigtail new technique uses small loop delimit from marking (Fig. 1). Handle adds box end lasso, which user makes second stroke marking. Timeout dwelling with mark. Button button...

Direct-touch interaction on mobile phones revolves around screens that compete for visual attention with users' real-world tasks and activities. This paper investigates the impact of these situational impairments touch-screen interaction. We probe several design factors gestures, under various levels environmental demands attention, in comparison to status-quo approach soft buttons. find presence distractions, gestures can offer significant performance gains reduced attentional load, while...

This paper explores the interaction possibilities enabled when barrel of a digital pen is augmented with multi-touch sensor. We present novel (MTPen) prototype and discuss its alternate uses beyond those standard stylus, such as allowing new touch gestures to be performed using index finger or thumb detecting how users grip device mechanism for mode switching. also hardware software implementation challenges in realizing our prototype, showcase one can combine different grips (tripod,...

Touchscreens continue to advance including progress towards sensing fingers proximal the display. We explore this emerging pre-touch modality via a self-capacitance touchscreen that can sense multiple above mobile device, as well grip around screen's edges. This capability opens up many possibilities for interaction. For example, using in an anticipatory role affords "ad-lib interface" fades different UI--appropriate context--as user approaches one-handed with thumb, two-handed index finger,...

We present Hover Widgets, a new technique for increasing the capabilities of pen-based interfaces. Widgets are implemented by using pen movements above display surface, in tracking state. Short gestures while hovering, followed down, access which can be used to activate localized interface widgets. By state movements, create command layer is clearly distinct from input interface. In formal experiment were found faster than more traditional activation technique, and also reduced errors due...

We explore techniques for hand-held devices that leverage the multimodal combination of touch and motion. Hybrid + motion gestures exhibit interaction properties combine strengths multi-touch with those motion-sensing. This affords touch-enhanced gestures, such as one-handed zooming by holding one's thumb on screen while tilting a device. also consider reverse perspective, motion-enhanced touch, which uses sensors to probe what happens underneath surface touch. Touching induces secondary...

Many interactive surfaces have the ability to detect shape of hands or objects placed on them. However, information is typically either condensed individual contact points categorized as discrete gestures. This does not leverage full expressiveness touch input, thus limits actions users can perform in applications. We present ShapeTouch, an exploration interactions that directly utilize manipulations and interactors. ShapeTouch infers virtual forces from regions motion enable interaction...
