Multi Point Haptic Feedback Above Interactive Surfaces

Fog Screen uses a water vaporizer to create the semi-transparent wall as well as leap motion or ultrasonic tracking device to register user’s body movements. While acknowledging the versatility of Fog Screen, several weaknesses can be mentioned. According to Puma [1] and Sherman [2], ultrasonic tracking performance tends to detract when operated in a noisy environment. This implies that, the interactivity of the system will be disrupted when used in noisy circumstances. Likewise, many users of the leap motion controller have often complained about the limited detection range of the device resulting in the failure of the device to recognize users’ hand movements [3]. Thus, a new interactive screen technology with a better tracking device is

The ultrasound works that you place a transducer on the gelcovered skin, and soundwaves are emitted into the body. This soundwaves travel until they reach different types of tissues which reflect the sound back, for example, when the soundwave passes from fluid to bone, some of the soundwaves reflects ans bounce off the bone back to the tranducer. Each time the soundwaves pass through a different medium within the body, whether it be oran tissue, donr och other tussues in the body this process continues.

Ultrasonography requires the use of some physics. Physics of Ultrasonography connects with how the functioning of the ultrasound machine works. When performing an ultrasound, “low intensity, high frequency sonic waves are directed into the soft tissues of the body” (Blevins et al. 1). Many sonic waves will directed right into the soft tissue to produce an image on the computer screen. William E. Blevins says, “The sonic waves called echoes, reflecting from tissues are ‘heard’ by the transducer” (Blevins et al. 1). This means the sounds of the tissue reflects back to the transducer and then back to the computer for evaluation. Then, “After interacting with the soft tissues, a portion of the sound is reflected back toward the source of the sound” (Blevins et al. 1). Basically the ultrasound evaluates the sound waves coming from inside of the body of the soft tissue. The sound waves travel back to the computer to produce an image on the screen. Finally, “These reflections or echoes are analyzed by a computer and a black and white image is produced” (Blevins et al. 1). When the black and white image appears back on the screen, the Ultrasound Technician will analyze the image on the computer

Gray-scale display relies on the amplitude of the backscattered ultrasound signal and the returning echoes that can be used to evaluate the motion of moving targets. If high frequency sound impinges on a stationary interface, the reflected ultrasound and the transmitted sound have essentially the same

It is obvious that the different parts of the body have different tactile sensation, which is similar to my hypothesis, and the most sensitive part is the ear, and the least sensitive part is the finger. This experiment is very successful, it can be seen that the method and process are reasonable, so it can be recommended. In the end, the pain is more than just what happened to the skin tactile sensor. It has a lot to do with what happens in the brain, for example, a tiny piece of debris in a finger is extremely painful, and cutting your leg may not hurt the same. So applications are used in hospitals, doctors can determine the severity of the injury to the patient's pain. And some diseases can be found due to the different parts of the

Body-borne computers, also referred to as wearables, are related to the fields of both ubiquitous computing and human-computer interaction. With ubiquitous computing, wearable computing is used to interweave technology into the everyday life, making technology pervasive and interaction frictionless. Through the history and development of wearable

These devices include virtually invisible headphones that monitor heart rate sensors worn under clothing to track the position, a temporary tattoo that records vital signs and health haptic shoe soles that communicate directions via GPS alerts vibration felt by the feet. The applications are many and varied: currently proposed haptic shoes to help blind people navigate while Glassware has been used by oncologists to aid in surgery through medical records and other visual information is accessed by means of 'voice commands.

Canny handheld gadgets have been utilized for almost 10 years as a part of the type of individual advanced colleagues (PDAs) and the first cell phones from merchants such as Research in Motion. Be that as it may, the presentation of the Apple iPhone and resulting iPad, alongside comparable gadgets controlled by programming from Google, Microsoft, and others, has introduced another period of versatile registering, with a huge number of cell phones and a huge number of tablets sold to customers and organizations. Three key elements have likely prodded the achievement of today 's tablets and cell phones. The movement from utilizing a stylus or physical console to multitouch cooperation’s with the gadget has for the most part brought about a superior, more natural client experience for customers; the

An ultrasound is an imaging procedure that produces ultra-high frequency sound waves (ultrasound). These sound waves bounce off internal bodily structures (Rugg n.pag.). Ultrasounds are a painless procedure that is performed by a doctor or technician that is specialized with training (Tavolacci 2316). First, the patient has to undress to expose the area that is being examined (Tavolacci 2316). Then, the doctor will apply a thin layer of gel to the area that is

"The use of ultrasound to vibrate a part to be cleaned while the part is immersed in a cleaning fluid. The process produces a very high degree of cleanliness, and is used for jewellery and ornately shaped items" [HarperCollins Publishers 1991, 1994, 1998, 2000, 2003]

The term “haptics” originated from the Greek word “haptikos” which means “able to grasp and perceive”. In general words, haptics can be defined as the ability of sensing and manipulating objects through touch. In terms of neuroscience, haptic perception includes two different sensory mechanisms which are the mechanoreceptors under the skin and the proprioceptors at muscles and joints.

In other work on creating a natural environment, Basdogan et al. [?] find that haptic technology can be used to simulate realistic surgery tool-tissue interactions including organ-force responses. Bara and Gentaz [?] show that children using both visual and haptic sensory channels in letter recognition and handwriting training have higher improvement in performance than using only the visual sensory channel. Although this and other research shows the benefit of utilizing haptic feedback in different areas, more research is needed to explore how haptically enhanced touchscreens can help users with touch based interactions.

A new bridge between man and computer is being created from the improvement of haptics

The key uses of Haptic Feedback are in the image outlines delineated by the feel sensation in a way like object simulation in a location near the user. In this way, it can be used in the training of individuals to perform tasks that require hand and eye coordination, including space ship

The idea of portable touchscreen devices have been many years in the making, In the 1966 television show “Star Trek Captain Kirk had the PADD (Personal Access Display Device) (Star Trek)” , “The 1968 movie 2001: Space Odyssey, there was a similar device called the Newspad” (Sande). A device by the same name was described in Hitchhiker’s Guide to The Galaxy aired on BBC radio in weekly segments, starting on March 8, 1978, and published in a novel in 1979 (Adams)
