The emergence of smart devices (e.g., smart watches and smart eyewear) is redefining mobile interaction from the solo performance of a smart phone, to a symphony of multiple devices. In this paper, we present Duet -- an interactive system that explores a design space of interactions between a smart phone and a smart watch. Based on the devices' spatial configurations, Duet coordinates their motion and touch input, and extends their visual and tactile output to one another. This transforms the… 
When bigger is simply better after all: Natural and Multi-Modal Interaction with Large Displays Using a Smartwatch
TLDR
The design and utilization of a multi-modal interaction interface based on a smartwatch combining the input modalities: touch gestures, non-touch gestures, and speech, and the suitability of the technology is described.
SenseBelt: A Belt-Worn Sensor to Support Cross-Device Interaction
TLDR
A sensing belt that enhances existing mobile interactions and enables low-cost, ad hoc sensing of cross-device gestures and interactions, and enables proxemic interactions between people and their personal devices is presented.
WatchPen: Using Cross-Device Interaction Concepts to Augment Pen-Based Interaction
TLDR
WatchPen is demonstrated, a smartwatch mounted on a passive, capacitive stylus that senses the usage context and leverages it for expression, and contains tools and parameters within the display and acts as an on-demand output.
Beats: Tapping Gestures for Smart Watches
TLDR
This paper presents the design of beating gestures and a rigorous empirical study that characterizes how users perform them, and derives thresholds for reliably distinguishing between simultaneous (under 30ms) and sequential (under 400ms) pairs of screen touches or releases.
WatchPen: Using Cross-Device Interaction Concepts to Augment Pen-Based Interaction
TLDR
WatchPen, a smartwatch mounted on a passive, capacitive stylus that senses the usage context and leverages it for expression, and contains tools and parameters within the display and acts as an on-demand output, provides users with a dynamic relationship between inputs and outputs.
FlexCase: Enhancing Mobile Interaction with a Flexible Sensing and Display Cover
TLDR
The rich design space of FlexCase is explored and how touch and flex sensing can be combined to support a novel type of gestures, which is called Grip & Bend gestures, and the underlying technology and gesture sensing algorithms are described.
Intelligent Shifting Cues: Increasing the Awareness of Multi-Device Interaction Opportunities
TLDR
Results of the study show that the cues can be effective in helping people to engage with multiple devices, but that the suitability of the proposed device and fit with task are important mediating factors.
SmartRSVP: Facilitating Attentive Speed Reading on Small Screen Wearable Devices
TLDR
SmartRSVP is presented, an attentive speed-reading system to facilitate text reading on small screen wearable devices that leverages camera-based visual attention tracking as a play/pause control channel and uses implicit physiological signal sensing to adjust speed in real-time to make text reading via Rapid Serial Visual Presentation (RSVP) more enjoyable and practical on smart watches.
Exploiting mid-air gestures to share data among devices
TLDR
MyoShare is presented, a system that allows content to be shared among devices using mid-air gestures that can be used at any time, independent of the current task and location of devices.
WRIST: Watch-Ring Interaction and Sensing Technique for Wrist Gestures and Macro-Micro Pointing
TLDR
It is demonstrated that WRIST affords and enables a number of novel yet simplistic interaction techniques, such as macro-micro pointing without explicit mode switching and wrist gesture recognition when the hand is held in different orientations.

SideSight: multi-"touch" interaction around small devices
TLDR
A prototype device with infra-red proximity sensors embedded along each side and capable of detecting the presence and position of fingers in the adjacent regions is described, which gives a larger input space than would otherwise be possible which may be used in conjunction with or instead of on-display touch input.
Sensing techniques for mobile interaction
TLDR
This work introduces and integrates a set of sensors into a handheld device, and demonstrates several new functionalities engendered by the sensors, such as recording memos when the device is held like a cell phone, switching between portrait and landscape display modes by holding the device in the desired orientation.
Disappearing mobile devices
TLDR
This paper extrapolate the evolution of mobile devices in one specific direction, namely miniaturization, and investigates what technology would be most likely to provide the basis for these devices, what abilities such devices can be expected to have, and whether or not devices that size can still allow for meaningful interaction.
eWatch: a wearable sensor and notification platform
TLDR
The motivation for developing a wearable computing platform is provided, a description of the power aware hardware and software architectures are described, and results showing how online nearest neighbor classification can identify and recognize a set of frequently visited locations are shown.
Whack gestures: inexact and inattentive interaction with mobile devices
TLDR
Whack Gestures is introduced, an inexact and inattentive interaction technique that could enable interaction without "getting it out," grasping, or even glancing at the device for mobile devices.
Back-of-device interaction allows creating very small touch devices
TLDR
This paper argues that the key to touch-enabling very small devices is to use touch on the device backside, and presents four form factor concepts based on back-of-device interaction and design guidelines extracted from a second user study.
DoubleFlip: a motion gesture delimiter for mobile interaction
TLDR
This paper presents DoubleFlip, a unique motion gesture designed as an input delimiter for mobile motion-based interaction that is extremely resistant to false positive conditions, while still achieving a high recognition rate.
Synchronous gestures for multiple persons and computers
TLDR
This research explores distributed sensing techniques for mobile devices using synchronous gestures by using tablet computers augmented with touch sensors and two-axis linear accelerometers (tilt sensors) to synchronize their time-stamped sensor data.
Lucid touch: a see-through mobile device
TLDR
Initial study results indicate that many users found touching on the back of the device to be preferable to touched on the front, due to reduced occlusion, higher precision, and the ability to make multi-finger input.
The smart phone: a ubiquitous input device
TLDR
It is shown how modern mobile phones can interact with their environment, especially large situated displays (Weiser's boards), and smart phone is used to describe an enhanced mobile phone.
