We present Skinput, a technology that appropriates the human body for acoustic transmission, allowing the skin to be used as an input surface. In particular, we resolve the location of finger taps on the arm and hand by analyzing mechanical vibrations that propagate through the body. We collect these signals using a novel array of sensors worn as an armband. This approach provides an always available, naturally portable, and on-body finger input system. We assess the capabilities, accuracy and… 
Skinput Technology- A Technique to act Skin as an Input Device
We present skinput , a technology that appropriates the human body for acoustic transmission, allowing the skin to be used as an input surface. In particular, we resolve the location of finger taps
SkinMotion: what does skin movement tell us?
TLDR
The potential applications of SkinMotion, an alternative interaction modality that reconstructs human motions from skin-stretching movements, are discussed and one specific instance -- finger motion detection using the skin movement on the dorsum of the hand is explored.
SonarWatch: appropriating the forearm as a slider bar
TLDR
This input method is suitable to be applied on extending the interaction space of mobile devices or providing more degrees-of-freedom for enhancing gaming experiences such as Kinect1.
SkinTrack: Using the Body as an Electrical Waveguide for Continuous Finger Tracking on the Skin
TLDR
SkinTrack is a wearable system that enables continuous touch tracking on the skin that consists of a ring, which emits a continuous high frequency AC signal, and a sensing wristband with multiple electrodes that can segment touch events at 99% accuracy, and resolve the 2D location of touches with a mean error of 7.6mm.
ActiTouch
TLDR
ActiTouch is developed, a new electrical method that enables precise on-skin touch segmentation by using the body as an RF waveguide and combined with computer vision, enabling a system with both high tracking precision and robust touch detection.
Botential: Localizing On-Body Gestures by Measuring Electrical Signatures on the Human Skin
TLDR
Botential uses the entire human body as an interactive surface to expand the usually limited interaction space in the context of mobility, and exhibits a number of advantages over previous approaches, including an increased sensing range that covers the whole body.
Enhancing Spatial Input on the Body with a Smart-Ring
TLDR
This work argues that human challenges remain: touch input on clothes will be hard due to a lack distinctive physical cues to guide users and the fact that many wearable scenarios involve eyes-free input, and proposes to address these issues by combining touch selections on the body with complementary input on a ring wearable.
SkinHaptics: Ultrasound focused in the hand creates tactile sensations
TLDR
This work presents a technology that could help to expand the output capability of on-body interfaces to provide tactile feedback without restricting the skin as an interaction surface, and demonstrates the potential of SkinHaptics.
Humantenna: using the body as an antenna for real-time whole-body interaction
TLDR
This paper uses the human body as an antenna for sensing whole-body gestures and shows robust gesture recognition with an average accuracy of 93% across 12 whole- body gestures, and promising results for robust location classification within a building.
Palm+Act: operation by visually captured 3D force on palm
TLDR
Recently, there has been considerable interest in technologies that appropriate human body parts, especially the skin, as an input surface for human-computer interfaces that enable the control of various systems in ubiquitous environments.

The sound of one hand: a wrist-mounted bio-acoustic fingertip gesture interface
TLDR
It is discovered that gentle fingertip gestures such as tapping, rubbing, and flicking make quiet sounds that travel by bone conduction throughout the hand, and this phenomenon is harnessed to build a wristband-mounted bio-acoustic fingertip gesture interface.
Scratch input: creating large, inexpensive, unpowered and mobile finger input surfaces
TLDR
A simple sensor is employed that can be easily coupled with existing surfaces, such as walls and tables, turning them into large, unpowered and ad hoc finger input surfaces, allowing any suitable surface on which it rests to be appropriated as a gestural input surface.

Passive acoustic knock tracking for interactive windows
TLDR
A novel interface that locates and characterizes knocks and taps atop a large glass window that requires only simple hardware, needs no special adaptation of the glass pane, and allows all transducers to be mounted on the inner surface, hence it is quite easy to deploy as a retrofit to existing windows.
