Haptics is a technology that adds the sense of touch to interactions with computers by applying forces, vibrations, or motions. This allows users to touch and manipulate virtual objects in a way that feels natural. As haptic devices continue advancing, they are being used in applications like gaming, virtual reality, teleoperation, and medical simulation by providing tactile feedback. Haptics has the potential to make digital interactions feel nearly indistinguishable from real world interactions.
This document describes the Skinput technology, which uses bio-acoustic sensing to localize finger taps on the skin. It can provide a direct manipulation graphical user interface projected directly onto the body. The technology was developed by researchers at Microsoft. It consists of a wearable arm band with multiple piezoelectric sensors of different resonant frequencies. When the skin is tapped, acoustic waves propagate through the body and are detected by the sensors. The location can be identified based on differences in signal arrival times and frequencies between sensors. User studies showed it can accurately detect taps on different areas of the arm.
Haptic technology uses tactile feedback and sensations to stimulate the sense of touch. It was first used in aviation to provide pilots vibrations that corresponded to turbulence or warnings. Now it is used widely in mobile devices, virtual reality, video games, product design, wellness, and automotive applications. It takes many forms like vibrations in phones and controllers, force feedback in joysticks, and textures in haptography. The main purpose is to allow communication between users and inanimate objects through the sense of touch.
Virtual reality systems consist of four main components:
1. A computer and software known as the reality engine
2. Input sensors like head-mounted displays, gloves, and audio units
3. Output sensors like head-mounted displays and audio units
4. The user, who directs the environment and reacts to it
Haptics is the technology of adding the sense of touch to virtual objects. It uses devices like the Phantom interface to allow users to feel 3D virtual objects. Haptics works by combining tactile and kinesthetic information sensed by receptors in the skin and muscles. This allows for applications in medical training simulation, virtual museums, and enhanced gaming through haptic feedback. Challenges include the high cost and size of haptic devices as well as rendering algorithms not matching continuous human touch. Future areas of growth include more widespread use of haptics in consumer electronics and improved holographic interaction.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Haptic technology
1. Haptic technology, or haptics, is a tactile feedback technology which takes
advantage of the sense of touch by applying forces, vibrations, or motions to the
user.[1] This mechanical stimulation can be used to assist in the creation of virtual
objects in a computer simulation, to control such virtual objects, and to enhance the
remote control of machines and devices (telerobotics). It has been described as "doing
for the sense of touch what computer graphics does for vision".[2] Haptic devices may
incorporate tactile sensors that measure forces exerted by the user on the interface.
Haptic technology has made it possible to investigate how the human sense of touch
works by allowing the creation of carefully controlled haptic virtual objects. These
objects are used to systematically probe human haptic capabilities, which would
otherwise be difficult to achieve. These research tools contribute to the understanding
of how touch and its underlying brain functions work.
The word haptic, from the Greek ἅπτικός (haptikos), means pertaining to the sense
of touch and comes from the Greek verb ἅπτεσθαι haptesthai, meaning to contact or to
touch.

History[edit source | edit]
One of the earliest applications of haptic technology was in large aircraft that
use servomechanism systems to operate control surfaces. Such systems tend to be
"one-way", meaning external forces applied aerodynamicallyto the control surfaces
are not perceived at the controls. Here, the missing normal forces are simulated with
springs and weights. In lighter aircraft without servo systems, as the aircraft
approached a stall the aerodynamic buffeting (vibrations) was felt in the pilot's
controls. This was a useful warning of a dangerous flight condition. This control
shake is not felt when servo control systems are used. To replace this missing sensory
cue, the angle of attack is measured and when it approaches the critical stall point,
a stick shaker is engaged which simulates the response of a simpler control system.
Alternatively, the servo force may be measured and the signal directed to a servo
system on the control, known as force feedback. Force feedback has been
implemented experimentally in some excavators and is useful when excavating mixed
material such as large rocks embedded in silt or clay. It allows the operator to "feel"
and work around unseen obstacles, enabling significant increases in productivity. The
first US patent for a tactile telephone was granted to Thomas D. Shannon in
1973.[3] An early tactile man-machine communication system was constructed by A.
Michael Noll at Bell Telephone Laboratories, Inc. in the early 1970s[4] and a patent
issued for his invention in 1975.[5]
Design[edit source | edit]
Haptics are enabled by actuators that apply forces to the skin for touch feedback, and
controllers. The actuator provides mechanical motion in response to an electrical
stimulus.
First generation haptics[edit source | edit]
Most early designs of haptic feedback use electromagnetic technologies such as
vibratory motors, like a vibrating alert in a cell phone or a voice coil in a speaker,
where a central mass is moved by an applied magnetic field. These electromagnetic
motors typically operate at resonance and provide strong feedback, but produce a
limited range of sensations and typically vibrate the whole device, rather than an
individual section.
3. Second generation haptics[edit source | edit]
Second generation haptics offered touch-coordinate specific responses, allowing the
haptic effects to be localised to the position on a screen or touch panel, rather than the
whole device. Second generation haptic actuator technologies include electroactive
polymers, piezoelectric, electrostatic and subsonic audio wave surface actuation.
These actuators allow to not only alert the user like first generation haptics but to
enhance the user interface with a larger variety of haptic effects in terms of frequency
range, response time and intensity. A typical first generation actuator has a response
time of 35-60ms, a second generation actuator has a response time of 5-15ms. User
studies also showed that haptic effects with frequencies below 150 Hz are preferred
by users. Frequencies of 250–300 Hz, which is the typical range of electromagnetic
systems are well suited for alerts but are perceived as annoying over time, which is
why first generation haptic systems used to enhance the user interface are often
deactivated by the users.
Third generation haptics[edit source | edit]
Third generation haptics deliver both touch-coordinate specific responses and
customisable haptic effects. The customisable effects are created using low latency
control chips.
To date two technologies have been developed to enable this; audio haptics[6] and
electrostatic haptics.[7]
A new technique that does not require actuators is called reverse-electrovibration. A
weak current is sent from a device on the user through the object they are touching to
the ground. The oscillating electric field around the skin on their finger tips creates a
variable sensation of friction depending on the shape, frequency, and amplitude of the
signal.[8]
Fourth generation haptics[edit source | edit]
Fourth generation haptics deliver pressure sensitivity, enabling how hard you press on
a flat surface to affect the response.
There are currently no commercially available (as of May 2013) platforms that use
this functionality, but the technology is in development by a number of firms. KDDI
and Kyocera jointly announced[9] in 2011 that they were collaborating on research.
And, at the Future World Symposium electronics industry conference, 2012,
HiWave's (haptics division now spun out to become Redux) CEO stated that the
company was also working on pressure sensitive technology.
4. In June 2013 a fourth generation haptics demonstration platform, called Bulldog, was
announced in the UK electronics publication Electronics Weekly.[10] This took the
force exerted by a finger into consideration when delivering the haptic feedback and
gave three levels of feedback from a flat panel.
Commercial applications[edit source | edit]
Tactile electronic displays[edit source | edit]
A tactile electronic display is a kind of display device that presents information in
tactile form. The two most popular kinds of tactile electronic displays are
various refreshable braille displays and the Optacon.
Teleoperators and simulators[edit source | edit]
Teleoperators are remote controlled robotic tools—when contact forces are
reproduced to the operator, it is called haptic teleoperation. The first electrically
actuated teleoperators were built in the 1950s at the Argonne National
Laboratory by Raymond Goertz to remotely handle radioactive substances. Since then,
the use of force feedback has become more widespread in other kinds of teleoperators
such as remote controlled underwater exploration devices.
When such devices are simulated using a computer (as they are in operator training
devices) it is useful to provide the force feedback that would be felt in actual
operations. Since the objects being manipulated do not exist in a physical sense, the
forces are generated using haptic (force generating) operator controls. Data
representing touch sensations may be saved or played back using such haptic
technologies. Haptic simulators are used in medical simulators and flight
simulators for pilot training.
Video games[edit source | edit]
Haptic feedback is commonly used in arcade games, especially racing video games. In
1976, Sega's motorbike game Moto-Cross,[11] also known as Fonz,[12] was the first
game to use haptic feedback which caused the handlebars to vibrate during a collision
with another vehicle.[13] Tatsumi's TX-1 introduced force feedback to car driving
games in 1983.[14]
Simple haptic devices are common in the form of game controllers, joysticks, and
steering wheels. Early implementations were provided through optional components,
such as the Nintendo 64 controller's Rumble Pak. Many newer generation console
controllers and joysticks feature built in feedback devices,
5. including Sony's DualShock technology. Some automobile steering wheel controllers,
for example, are programmed to provide a "feel" of the road. As the user makes a turn
or accelerates, the steering wheel responds by resisting turns or slipping out of
control.
In 2007, Novint released the Falcon, the first consumer 3D touch device with high
resolution three-dimensional force feedback; this allowed the haptic simulation of
objects, textures, recoil, momentum, and the physical presence of objects in
games.[15][16]
Personal computers[edit source | edit]
In 2008, Apple's MacBook and MacBook Pro started incorporating a "Tactile
Touchpad" design[17][18] with button functionality and haptic feedback incorporated
into the tracking surface.[19] Products such as theSynaptics ClickPad[20] followed
thereafter.
Mobile devices[edit source | edit]
Tactile haptic feedback is becoming common in cellular devices. Handset
manufacturers like Nokia, LG and Motorola are including different types of haptic
technologies in their devices; in most cases, this takes the form of vibration response
to touch. Alpine Electronics uses a haptic feedback technology named PulseTouch on
many of their touch-screen car navigation and stereo units.[21] The Nexus One features
haptic feedback, according to their specifications.[22]
In February 2013, Apple Inc. was awarded the patent for a more accurate haptic
feedback system that is suitable for multitouch surfaces. Apple's U.S. Patent for a
"Method and apparatus for localization of haptic feedback"[23] describes a system
where at least two actuators are positioned beneath a multitouch input device to
provide vibratory feedback when a user makes contact with the unit. More
specifically, the patent provides for one actuator to induce a feedback vibration, while
at least one other actuator creates a second vibration to suppress the first from
propagating to unwanted regions of the device, thereby "localizing" the haptic
experience. While the patent gives the example of a "virtual keyboard," the language
specifically notes the invention can be applied to any multitouch interface.[24]
Virtual reality[edit source | edit]
Haptics are gaining widespread acceptance as a key part of virtual reality systems,
adding the sense of touch to previously visual-only solutions. Most of these solutions
use stylus-based haptic rendering, where the user interfaces to the virtual world via a
6. tool or stylus, giving a form of interaction that is computationally realistic on today's
hardware. Systems are being developed to use haptic interfaces for 3D modeling and
design that are intended to give artists a virtual experience of real interactive
modeling. Researchers from the University of Tokyo have developed 3D holograms
that can be "touched" through haptic feedback using "acoustic radiation" to create a
pressure sensation on a user's hands (see future section). The researchers, led by
Hiroyuki Shinoda, had the technology on display at SIGGRAPH 2009 in New
Orleans.[25]
Research[edit source | edit]
Research has been done to simulate different kinds of taction by means of high-speed
vibrations or other stimuli. One device of this type uses a pad array of pins, where the
pins vibrate to simulate a surface being touched. While this does not have a realistic
feel, it does provide useful feedback, allowing discrimination between various shapes,
textures, and resiliencies. Several haptics APIs have been developed for research
applications, such as Chai3D, OpenHaptics, and the Open Source H3DAPI.
Medicine[edit source | edit]
Haptic interfaces for medical simulation may prove especially useful for training in
minimally invasive procedures such as laparoscopy and interventional radiology,[26] as
well as for performing remote surgery. A particular advantage of this type of work is
that surgeons can perform more operations of a similar type with less fatigue. It is
well documented that a surgeon who performs more procedures of a given kind will
have statistically better outcomes for his patients.[citation needed] Haptic interfaces are also
used in rehabilitation robotics.
In ophthalmology, haptic refers to supporting springs, two of which hold an
artificial lens within the lens capsule after the surgical removal of cataracts.[citation needed]
A Virtual Haptic Back (VHB) was successfully integrated in the curriculum at
the Ohio University College of Osteopathic Medicine.[27] Research indicates that VHB
is a significant teaching aid in palpatory diagnosis (detection of medical problems via
touch). The VHB simulates the contour and stiffness of human backs, which are
palpated with two haptic interfaces (SensAble Technologies, PHANToM 3.0). Haptics
have also been applied in the field of prosthetics and orthotics. Research has been
underway to provide essential feedback from a prosthetic limb to its wearer. Several
research projects through the US Department of Education andNational Institutes of
Health focused on this area. Recent[timeframe?] work by Edward Colgate, Pravin
7. Chaubey, and Allison Okamura et al. focused on investigating fundamental issues and
determining effectiveness for rehabilitation.[citation needed]
Robotics[edit source | edit]
The Shadow Hand uses the sense of touch, pressure, and position to reproduce the
strength, delicacy, and complexity of the human grip.[28] The SDRH was developed by
Richard Greenhill and his team of engineers in London as part of The Shadow Project,
now known as the Shadow Robot Company, an ongoing research and development
program whose goal is to complete the first convincing artificial humanoid. An early
prototype can be seen in NASA's collection of humanoid robots, or robonauts.[29] The
Shadow Hand has haptic sensors embedded in every joint and finger pad, which relay
information to a central computer for processing and analysis. Carnegie Mellon
University in Pennsylvania and Bielefeld University in Germany found The Shadow
Hand to be an invaluable tool in advancing the understanding of haptic awareness, and
in 2006 they were involved in related research.[citation needed] The first PHANTOM,
which allows one to interact with objects in virtual reality through touch, was
developed by Thomas Massie while a student of Ken Salisbury at MIT.[30]
Arts and design[edit source | edit]
Touching is not limited to feeling, but allows interactivity in real-time with virtual
objects. Thus, haptics are used in virtual arts, such as sound synthesis or graphic
design and animation.[citation needed] The haptic device allows the artist to have direct
contact with a virtual instrument that produces real-time sound or images. For
instance, the simulation of a violin string produces real-time vibrations of this string
under the pressure and expressiveness of the bow (haptic device) held by the artist.
This can be done with physical modelling synthesis.
Designers and modellers may use high-degree-of-freedom input devices that give
touch feedback relating to the "surface" they are sculpting or creating, allowing faster
and more natural workflow than traditional methods.[31]
Artists working with haptic technology such as vibrotactile effectors are Christa
Sommerer, Laurent Mignonneau, and Stahl Stenslie.[citation needed]
Future applications[edit source | edit]
Future applications of haptic technology cover a wide spectrum of human interaction
with technology. Current[timeframe?] research focuses on the mastery of tactile
interaction with holograms and distant objects, which if successful may result in
applications and advancements in gaming, movies, manufacturing, medical, and other
8. industries.[citation needed] The medical industry stands to gain from virtual and
telepresence surgeries, which provide new options for medical care. The clothing
retail industry could gain from haptic technology by allowing users to "feel" the
texture of clothes for sale on the internet.[32] Future advancements in haptic
technology may create new industries that were previously not feasible nor realistic.
Holographic interaction[edit source | edit]
Researchers at the University of Tokyo are working on adding haptic feedback
to holographic projections. [timeframe?] The feedback allows the user to interact with a
hologram and receive tactile responses as if the holographic object were real. The
research uses ultrasound waves to create acoustic radiation pressure, which provides
tactile feedback as users interact with the holographic object.[25] The haptic
technology does not affect the hologram, or the interaction with it, only the tactile
response that the user perceives. The researchers posted a video displaying what they
call the Airborne Ultrasound Tactile Display.[25] As of 2008 the technology was not
ready for mass production or mainstream application in industry, but was quickly
progressing, and industrial companies showed a positive response to the
technology.[33] This example of possible future application is the first in which the
user does not have to be outfitted with a special glove or use a special control—they
can "just walk up and use [it]".[33]
Future medical applications[edit source | edit]
One currently developing[timeframe?] medical innovation is a central workstation used by
surgeons to perform operations remotely. Local nursing staff set up the machine and
prepare the patient, and rather than travel to an operating room, the surgeon becomes
a telepresence. This allows expert surgeons to operate from across the country,
increasing availability of expert medical care. Haptic technology provides tactile and
resistance feedback to surgeons as they operate the robotic device. As the surgeon
makes an incision, they feel ligaments as if working directly on the patient.[34]
As of 2003, researchers at Stanford University were developing technology to
simulate surgery for training purposes. Simulated operations allow surgeons and
surgical students to practice and train more. Haptic technology aids in the simulation
by creating a realistic environment of touch. Much like telepresence surgery, surgeons
feel simulated ligaments, or the pressure of a virtual incision as if it were real. The
researchers, led by J. Kenneth Salisbury Jr., professor of computer science and
surgery, hope to be able to create realistic internal organs for the simulated surgeries,
but Salisbury stated that the task will be difficult.[32] The idea behind the research is
that "just as commercial pilots train in flight simulators before they're unleashed on
9. real passengers, surgeons will be able to practice their first incisions without actually
cutting anyone".[32]
According to a Boston University paper published in The Lancet, "Noise-based
devices, such as randomly vibrating insoles, could also ameliorate age-related
impairments in balance control."[35] If effective, affordable haptic insoles were
available, perhaps many injuries from falls in old age or due to illness-related balance-
impairment could be avoided.
