Piezoelectricity is a well-known effect in which stretching or compressing a material causes it to generate an electrical voltage, or the reverse, in which an applied voltage causes it to expand or contract. Studies proved that using a few atomic thicknesses of two-dimensional materials such as molybdenum disulfide opens the potential for new types of mechanically controlled electronic devices. Using a single layer of atoms could be made as nanotechnology clothing in the form of wearable devices, optically transparent, extremely light, and very bendable and stretchable during use. The study was supported by the U.S. Department of Energy (DOE), Office of Basic Energy Sciences (BES) (No. DE-FG02-07ER46394) and U.S. National Science Foundation (DMR-1122594).
Scientists envision that these nanotechnology clothing could have a future possibility to change the way humans interact with computers, mobile phones, and optical head-mounted displays. For example, using such nanotechnology clothing as a computer glove may eliminate the need for using traditional computer input devices such as touchscreen, keyboards, or gesture tracking cameras. Also, utilizing nanotechnology clothing as a wearable suit may allow tracking the motion of its users, which can eliminate the need of using traditional motion tracking techniques. This includes optical tracking systems that utilize tracking cameras, and magnetic tracking systems that use magnetic sensors.
However, until now there has been no single method or system that utilizes nanotechnology clothing to achieve the aforementioned goals or objectives. In fact, if one day became possible to utilize nanotechnology clothing as wearable computer input devices that will change the way we interact with computers, mobile phones, and optical head-mounted displays. Consequently, our productivity and communication with each other can be dramatically improved.
The present invention discloses a wearable nanotechnology clothing for human-computer interaction. In one embodiment, the present invention is in the form of wearable gloves that capture the motion of a user's hand or fingers and provide the computer system with an immediate computer input representing an interaction with a computer application. Thus, the user can interact with computers, mobile phones, tablets, or optical head-mounted displays without the need for using a keyboard, touchscreen, or tracking camera that captures the motion of the user's hands.
In another embodiment, the present invention is in the form of a suit that can worn by a user to track the motion of the user's body. This is to serve broad computer applications in many fields including entertainment, gaming, sports, medical and robotics. For example, in filmmaking, the present invention can be used to record actions of human actors, and transpose that information to create animated digital character models in three-dimensions. In game development, the present invention can manipulate the three-dimensional movement of a virtual character or avatar on a computer display to simulate the user's body motion in martial art moves, sport, or other gaming actions. In medical as well, the present invention can be used to track the motion of patients during rehabilitation, and present a simulation of their motion on a computer display for tracking and medical analysis purposes.
Generally, one of the main advantages of the present invention is that user's motion accurately captured regardless of the user's location or the light exposure. For example, the present invention can capture the user's motion while they are swimming or diving underwater. Also, the present invention can capture the user's motion in darkness, indoors or outdoors while they are sleeping, walking, or performing different activities. The tracked data of the user's body is wirelessly sent, in real-time, to an electronic device such as a computer, tablet or mobile phone, or stored for later transfer to a computer. This data allows a simulation of the shape and motion of the user's body to serve various computer applications.
Overall, the above Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
According to one embodiment of the present invention,
A tension force is applied to the stretched area of the atomically thin material, and a compression force is applied to the compressed area of the atomically thin material when the finger is bent. At this moment, as known in the art, positive and negative polarized charges are squeezed from each single layer of atoms as it is being stretched. The magnitude of the positive and negative polarized charges represents the extent of stretching and compressing of the atomically thin material, which also represents the degree of the finger bending or the rotational angles of the finger joints.
Sensing each unique magnitude of the positive and negative polarized charges and capturing the picture of the finger bending at the moment of each unique magnitude allows us to interact with computers in an intuitive manner. This is achieved by creating a database that associates each unique magnitude of the positive and negative polarized charges with a unique finger bending. Each unique finger bending is also associated with a computer input to be provided to the computer system once the finger is bent. At the moment of bending the finger, the magnitude of the positive and negative polarized charges is sensed by a polarizing sensor, and the database is checked against the magnitude to determine the finger bending associates with this magnitude. Once the finger bending is determined, a computer input associated with the finger bending is provided to the computer system to allow the user to interact with a computer application presented on the computer display.
According to the above description, in one embodiment, the present invention discloses a computer input method comprising: sensing each unique magnitude of the positive and negative polarized charges generated on an atomically thin material attached to a finger; associating the each unique magnitude with a corresponding finger bending; associating the corresponding finger bending with a computer input to be provided to a computer system once the each unique magnitude is sensed.
Using the present invention with a single finger allows providing a number of different computer inputs to the computer system. Using the present invention with the ten fingers of left and right hands allows providing a large number of different computer inputs to the computer system. In this case, the present invention comes in the form of two gloves that can be worn on a user's hands to detect the motion of the user's ten fingers. In one embodiment, the computer input provided by the present invention represents letters, numbers or signs, which replaces the need for using a computer keyboard, or using a virtual keyboard on a touchscreen. In this case, the user can type by moving their hands in the air without the need for using a desk or surface to support the hands during typing. This allows the user to type while they are walking, lying supine, or being away from the computer.
In another embodiment, each unique computer input provided by the present invention represents invoking a program command to perform a certain action on the computer display, similar to the functions of MICROSOFT OFFICE keyboard shortcuts, GOOGLE CHROME keyboard shortcuts or the like. In yet another embodiment, the computer input provided by the present invention represents an interaction with a graphical user interface of a GPS or Radio of a car. This allows the user to use the GPS or Radio of the car while driving. In also another embodiment, the computer input provided by the present invention represents an interaction with a game application presented on a digital display. This replaces the need for using a game controller or keyboard to interact with various gaming applications.
In one embodiment, the present invention is utilized to facilitate the user's interaction with the digital data presented on an optical head-mounted display. This utilization of the present invention is very valuable since the user of optical head-mounted displays cannot employ traditional computer input devices such as computer mouses, keyboards or touchscreens while standing or walking Moreover, in such a case, there is no need for using a tracking camera to track the motion of the user's hands. Also, there is no need for using a speech recognition system to interact vocally with the optical head-mounted display. This dramatically improves the user's interaction with modern optical head-mounted displays to serve various gaming, entertainment, and military applications.
Overall, the same concept of sensing a finger bending to interact with a computer can be utilized to sense the motion or joints rotation of different parts of a human's body. For example,
The present invention facilitates communication between the computer system and several everyday human tools without additional connections. For example, it is possible for the user of the present invention to employ a regular pen as a computer pen input device. The user can write on a regular piece of paper using the regular pen while the present invention simultaneously detects the user's hand/finger motions and provides immediate text input to the computer system. The present invention converts a regular computer display into a touch screen where the user can move their finger to point at any specific icon or menu on the computer display, and the regular computer display will react as if it were a touchscreen. This is done by detecting the user's hand/finger movements relative to the computer display's position and dimensions to manipulate the icons or menus to interact with the movement of the user's hand/finger.
Moreover, the present invention can provide a warning tool to alert users when they move their body in an awkward position during different activities such as sleeping, working out, or lifting a heavy object that could injure their back or other body parts. This is achieved by detecting the motion of each part of the user's body and comparing this data with a database that associates each risky motion with a warning message to alert the user of their risky motion. The warning message can be in the form of a sound or automated vocal message generated by a mobile phone, or a digital text that appears on the mobile phone display. In this case, the present invention is wirelessly connected to mobile phone or other electronic devices such as an optical head-mounted display.
Additionally, in the 3D movie production techniques, the present invention gives a comprehensive yet inexpensive tool for the CG-animation or the 3D cartoon movies, wherein it is easy to capture the different motions of the performers to emulate or copy these motions into a movement for 3D cartoon characters. In sports training and analysis, the present invention is a perfect tool to be utilized in many applications that provide the computer system with data simulating the details of the user's body movements while practicing different sports, such as shooting a basketball into a net, shooting a ball in a soccer game, or swimming. The user can view the simulation of all such details on the computer display to recognize their mistakes. Also collecting the data of the players' motions using the present invention facilitates the analysis of the entire game to locate the team's/individual's mistakes during a game.
Also, the present invention also facilitates remote interactive virtual sporting, where two or more players can participate and compete in playing games remotely, whereas detecting each player's motions provide immediate input to the computer that can be connected to the Internet to transfer the action of the player to the others in different locations. This allows for the involvement of several participants from different geographical location.
A main advantage of the present invention is that the capturing of the user's movement is accurately achieved regardless of the user's location, and the light exposure. The tracked data of the user's body is wirelessly sent, in real-time, to en electronic device such as a computer, tablet, or mobile phone, or stored for later transfer to the electronic device. This data allows simulating the shape and motion of the user's body in three-dimensions on the device display.
Another advantage of the present invention is solving the problem or constrains of using traditional recognition methods of hand gestures that utilize digital cameras or depth sensing cameras. The digital camera can be a computer camera that captures images of the user's hand in front of the computer, which is then interpreted by a computer vision program that analyzes the pictures to determine the hand gestures in real time. The depth sensing camera detects the distances between the camera and the hands or fingers and accordingly can determine the hand gestures upon the detected distances. However, as well known, using a digital camera or depth sensing camera comes with constrains and limitations. For example, the user's hand has to be directly facing the digital camera or depth sensing camera. Certain tilting or rotation of the user's hand stops the hand gesture recognition. This prevents the user from using such techniques while they are moving around the computer or lying supine. Additionally, if there is an object located between the user and the camera, then the process stops until the object is removed. Moreover, minor hand gestures cannot be recognized or detected when using the digital cameras or the depth sensing camera. All such problems regarding the use of the digital cameras and depth sensing cameras are solved with the use of the present invention.
As described previously, the present invention discloses nanotechnology clothing to detect the motion or rotation of different joints of a human's body. In one embodiment, the present invention is comprised of a few atomic thicknesses of two-dimensional materials such as molybdenum disulfide, shaped in the form of a wearable cloth such as gloves, shirt, pants, or suit. A plurality of sensors is connected to certain spots of the wearable cloth to sense the positive and negative polarized charges. These certain spots are located where the motion or rotation of the body's joints causes stretching or compressing of the two-dimensional materials. The sensors are connected to a microprocessor that receives the output of the sensors and wirelessly provides a computer system with an immediate input representing the motion or rotation of the body's joints.
In one embodiment, the immediate input provided by the microprocessor to the computer system is checked against a first database that associates each unique magnitude of positive and negative polarized charges, sensed at a certain spot, with a motion of joint rotation at this certain spot. The value of the rotation corresponds to the magnitude of the positive and negative polarized charges. In another embodiment, a second database is used to associate each joint rotation of the user's body with a command that performs a certain action on the computer display. The certain action can represent a keyboard shortcut, typing a letter or number, or manipulating an object to move in 2D or 3D on the computer display. The object moved on the computer display can be a virtual character or avatar of a gaming application, or a 3D simulation of the user's body.
In one embodiment, the computer system that receives the output of the microprocessor is a computer system of an electronic device such as mobile phone, tablet, computer, or optical head-mounted display. In this case, the microprocessor is wirelessly connected to the electronic device, and the display of the electronic device is used to present the computer application which the user is interacting with it. As mentioned previously, the computer application can be a desktop application or Web-based application. Also, as described previously, when using the present invention as a warning tool to alert users when they move their body in an awkward position, in this case, the computer application generates warning messages in the form of sounds or digital text.
It is important to note that MoS2 is just one of a group of 2D semiconducting materials known as transition metal dichalcogenides, all of which have similar piezoelectric properties. However, the atomically thin material can be ‘nano-laminating’ atomic sheets of different van der Waals (vdW) materials. These vdW building blocks are materials in which the atomic bonds are strong in two directions, but weak in the third. This gives them a layered structure, like a stack of paper, and makes it easy to separate (‘exfoliate’) the layers. Common vdW materials include graphite, which can be exfoliated to form single sheets (graphene); many high-T superconductors; and layered chalcogenides such as MoS2. Many of these systems already display behavior due to the low dimensionality of their electronic structure. The technique can use re-stacking dissimilar vdW materials in a controlled fashion (‘nano-lamination’). Using this technique, it is possible to create heterostructures that are essentially designer materials, with control at the level of the individual atomic layer.
