DESCRIPTION
Certain exemplary embodiments can relate to human-machine interaction. More particularly, certain exemplary embodiments can relate to human-machine interaction for users wearing gloves on their hands for nearly any purpose. Example gloves can include environmental protective gloves such as those worn by astronauts, firefighters, deep-sea divers, bomb-disposal units, and/or hazardous material handling crew members. Other example gloves can include gloves worn to prevent contamination such as in semiconductor manufacturing, space hardware integration, and/or biological material handling. Typical gloves often can be bulky and/or can impede normal hand and/or finger motion, making it difficult or impossible to use a standard keyboard, mouse, and/or other human-machine interfaces.
In certain exemplary embodiments, a gloved human-machine interface can comprise protective outer gloves, inner gloves, vibrotactile actuators, a motion tracking camera, light emitting diodes, flexion sensors, portable electronics, data/power connections, a harness, and/or a computing system. Certain exemplary embodiments can allow a person to interact with a computer or other information device while wearing protective gloves, to enter numerical and/or textual data, to interact with a graphical user interface, to spatially designate points on a visual display (for navigation and/or annotation), and/or to generate tactile alerts and/or warnings. Certain exemplary allow a person to use protective gloves to replicate the functionality of a standard desktop mouse and/or keyboard.
Certain exemplary embodiments can replicate the familiar capabilities of standard desktop human interface devices and/or input devices (e.g., computer mouse and/or keyboard) using the protective gloves on an astronaut's hands as surrogates. Astronauts wearing space suits during extra-vehicular activity (EVA) currently have extremely limited access to mobile communications and computing. Certain exemplary embodiments can solve this problem by enabling the gloves on the crewmembers hands to be used as input devices. Certain exemplary embodiments can solve a similar problem for intra-vehicular activity (IVA), permitting crewmembers wearing protective gloves to access on-board data and/or communications systems. The ability to use the gloves for point-and-click (mouse-like) interactions and/or for text and/or numerical data entry (keyboard-like) interactions can enable a broad range of applications, including but not limited to: interaction with procedures or checklists, text communications, document browsing/editing, image annotation, cataloging of geological samples, navigation, voice and/or data communications, on-board systems control and/or monitoring, and/or robotic control.
Certain exemplary embodiments can permit protective gloves to be used as human-machine interface devices, allowing an operator in an environmental protection suit to perform keyboard and/or mouse interactions. Certain exemplary embodiments can use synergy between motion tracking, gesture recognition, and/or tactile feedback to create an intuitive human-machine interface that can emulate familiar desktop input devices.
Tactile feedback can be enabled by a unique concept that can use the pressurized gloves themselves as a transport mechanism for carrying tactile vibrations from motors to human fingertips.
Certain exemplary embodiments can combine any of three elements to recreate the functionality of a standard desktop computing mouse and/or keyboard using the gloves on a suited operator's hands: motion tracking, finger gesture recognition, and/or tactile feedback.
Certain exemplary embodiments can operate in two modes: MOUSE and KEYBOARD. In MOUSE mode, certain exemplary embodiments can emulate the functionality of a computer mouse. Hand motion, through the motion tracking element, can permit left or right hand position to drive the movement of a cursor on a visual display in the same manner as a computer mouse. Finger tapping motions from one or more fingers can be recognized by the finger gesture recognition element and/or translated into mouse click events. Tactile feedback in one or more fingers can provide the physical sensation of button clicks, the edges of windows, and/or other graphical user interface (GUI) interactions. In addition to general GUI interactions, MOUSE mode can permit text and/or data entry using an on-screen virtual keyboard through a “hunt-and-peck” approach using cursor movement and/or mouse clicks to tap keys.
In KEYBOARD mode, certain exemplary embodiments can emulate the functionality of a standard QWERTY keyboard (or any other computer keyboard and/or numeric keypad). Hand motion, through the motion tracking element, can control the mapping from the fingers on right and/or left hands to keys on a virtual keyboard. When KEYBOARD mode is initialized, the fingers on the left hand can map (from pinky to index) to “a,” “s,” “d,” “f” and/or the fingers on the right hand can map to “j,” “k,” “l,” “;”. Through the motion tracking element, translation of hand position can change the mapping to mimic the change of finger position on a physical keyboard. A forward motion with the left hand can change the mapping so that the index finger rests on the “r” key. Finger tapping motions with any finger can generate a keyboard stroke of the appropriate key. Tactile feedback can provide the physical sensation of button clicks and/or a physical “bump” feel to the transition between hand positions on the keyboard.
In certain exemplary embodiments, hand motion tracking can be used to map hand position to a single key on a virtual keyboard. In this form, a finger tap from any finger on that hand can result in that key being registered. Thus a glove with only a single flexion sensor and single tactile assembly can be used in KEYBOARD mode.
The constraints of a protective suit can make conventional modes of human-machine interaction difficult. In mobile environments, standard I/O approaches such as a physical keyboard, mouse, and large liquid crystal displays (LCDs) can be unavailable. While adaptations of smaller LCDs and keyboards used in state-of-the-art Personal Digital Assistants (PDAs) and smart phones are possible, they have not proven to be practical when a human is wearing protective gloves. Restrictions imposed by the space suit glove, or other bulky gloves, make interacting with a small keyboard, either a physical keypad or virtual (touch screen), impractical.
Introducing tactility into a data entry system can increase crewmember performance and/or reduce mental workload. Certain information displays can overly rely on visual rendering, taxing cognitive resources already heavily burdened by the operational environment. The resulting information overload can result in poor multi-tasking efficiency, poor task performance, and/or increased frequency of errors. Through the synergistic combination of motion tracking, finger gesture recognition, and/or tactile feedback, certain exemplary embodiments can enable the kind of heads-up operation touch typists use to efficiently key text. Tactile features can introduce physical sensations to increase throughput, reduce errors, and/or increase user satisfaction.
Certain exemplary embodiments can place all components requiring electrical current outside of a pressure layer of a protective glove. Placement of all components requiring electrical current outside of this layer of the glove can avoids penetrations through the pressure layer that would require a leaky, or failure prone, seal. The pressure layer can comprise electrically insulating material. Placement of current-carrying components outside of this layer can prevent a shock hazard due to the introduction of current-carrying components into the glove. Furthermore, placement of components outside of the pressure layer can prevent a fire hazard due to introduction of potentially spark-generating electronics into the highly oxygenated environment within a protective suit.
Certain exemplary embodiments of a human-machine interface for glove-wearing humans can be constructed as shown in FIG. 1. Any number of light-emitting diodes 11 can be integrated into the back of either and/or each of two outer gloves 12. A flexible connector 17 can communicatively couple internal glove electronics (shown in FIG. 2 and described below) to an external connector 19, thereby providing a communications linkage to a computing system 23. A camera 13 (such as the FLEX:V100 available from NaturalPoint, Inc. of Corvallis, Oreg.) can comprise a sensor, signal processing electronics, and/or optics housed within an enclosure. The camera 13 can be operatively attached to a user's torso (for example on the outside of a space suit), adjacent to the user's head (for example next to the helmet of a space suit), or in any other location that provides visibility to the user's hands. A camera cable 18 can communicatively couple the camera to an external connector 19, thereby providing a communications linkage to a computing system 23. The computing system 23 can encompass a processor, digital data input and/or output, and/or a power supply. Computing system 23 in turn can be connected to, or encompassed within, additional computing, communications, and/or other user interface elements, such as a heads-up visual display, that are specific to particular uses of certain exemplary embodiments.
FIG. 2 shows a perspective view of the interior of the exemplary right hand glove of FIG. 1. An inner glove 21, which can be enclosed by the outer glove 12, can be fabricated from multiple layers which can include a pressure layer comprising a substantially gas-impermeable material (such as urethane or latex) and/or a layer of restraint material (such as synthetic polyester fabric). Right and left hand gloves can be constructed in a like manner. Tactile actuation assemblies 15, each of which can comprise a vibrational motor and/or a tactile adapter (shown in FIG. 5 and described below), can be operatively attached to the inner glove 21 aligned with any and/or each finger, and/or can be held in position by stitching, sandwiched layers of glove fabric, adhesive, and/or by any other means. The tactile actuation assemblies 15 can connect to a wiring harness 16. The wiring harness 16 can connect to leads on portable electronics 14 to the tactile actuation assemblies 15, light-emitting diodes 11, and/or flexion sensors 20. The wiring harness 16 can be fabricated from insulated wire and/or flexible circuit material and/or can be routed within the fabric of the outer glove 12. Flexion sensors 20 can be placed within the outer glove 12 aligned with any and/or each finger, and/or can be held in position by a fabric sleeve, sandwiched layers of glove fabric, and/or flexible tubing. The flexion sensors 20 can comprise a carbon/polymer based ink (available from Flexpoint Sensor Systems of Draper, Utah) and/or similar material that can vary in resistance when flexed (and thus can serve as a finger bend sensor). Light-emitting diodes 11 (for example 850 nm high-efficiency, wide angle LEDs) can be integrated into the outer glove 12 such that they protrude through the outer glove, or are provided with a substantially transparent window or cover, in a manner that makes them visible to the camera. The portable electronics 14 comprises a microprocessor, signal conditioning/amplification, analog-to-digital conversion, pulse-width modulation, analog logic circuitry, digital input/output, energy storage, power conditioning, and/or tactor driver circuitry integrated on a printed circuit board. A flexible cable 17 can communicatively connect the portable electronics to a glove connector 19, thereby providing a communications and/or power linkage to the computing system 23 shown in FIG. 1. The flexible cable 17 can thus carry electrical power, commands to tactile actuators, mode change commands, light emitting diode flashing and/or dimming commands, and/or any other information or commands from the computing system 23 to portable electronics 14, and/or carry event messages, diagnostic messages, sensor data messages, and/or any other information from the portable electronics 14 to the computing system 23. FIG. 2 also identifies the sectional view “A-A” cut plane for FIG. 9.
FIG. 3 shows a perspective view of the exemplary embodiment shown in FIG. 2, illustrating the inner glove 21 and placement of glove components with the outer glove, flexible cable, and wiring harness omitted.
FIG. 4 shows an exploded view of the exemplary embodiments shown in FIG. 3, and showing placement of exemplary glove components with the outer glove, flexible cable, and wiring harness omitted.
FIG. 5 shows a perspective view of an exemplary embodiment of a tactile actuation assembly 15, which can comprise a vibrational motor 25 and/or a tactile adapter 26. The tactile adapter 26 can be fabricated from plastic, rubber, metal, or any other suitable material. The vibrational motors 25 can be linear resonant actuators (available from Precision Microdrives Limited, London, UK), eccentric rotating mass motors (available from Precision Microdrives Limited, London, UK), plunger-type linear electro-magnetic motors (available from Engineering Acoustics Inc. of Casselberry, Fla.), piezoelectric actuators, electro-active polymer actuators, voice-coil actuators, or any other motor type that generates sufficient vibrational energy in a suitably small form factor. The tactile adapter 26 can have any number, or no, holes to permit the adapter to be operatively attached to the inner glove through stitching.
FIG. 6 shows an exploded view of FIG. 5.
FIG. 7 shows a top view of an exemplary tactile actuation assembly 15.
FIG. 8 shows a section view taken at section B-B of FIG. 7 of an exemplary tactile actuation assembly 15. In certain exemplary embodiments, a linear resonant actuator type vibrational motor 25 can be held rigidly within a tactile adapter 26. In certain exemplary embodiments, the tactile adapter 26 can be fabricated such that a vibrational motor 25 is in direct contact with the inner glove to which the adapter can be operatively attached by stitching, sandwiched layers of glove fabric, adhesive, and/or by any other means.
FIG. 9 shows a section view taken at section “A-A” of FIG. 2. In certain exemplary embodiments, such as a space suit, the gas within the pressure layer of the inner glove 21 can be maintained at a positive pressure differential with respect to the atmospheric pressure of the outside environment. In such cases, the inner glove layers can become stiffened, similar to the surface of an inflated balloon. As a result, the inner glove material can become an efficient carrier of mechanical vibrations. The tactile adapter 26 can be operatively attached to the fabric of the inner glove 21 such that vibrations in the tactile adapter result in oscillatory motion in the inner glove 21. An amplitude-modulated drive voltage can be applied to the motor from the portable electronics 14 through the wiring harness 16. The resulting oscillatory forces in the vibrational motor 25 can be applied through the tactile adapter 26 to the material of the inner glove 21, causing physical vibrations (oscillatory displacements). The pressure stiffened inner glove material can carry these vibrations to the human finger 28 inside of the glove, creating a perceptible tactile sensation.
FIG. 10 is a block diagram of exemplary major components of an exemplary embodiment of the portable electronics 14 and its connection, through the wiring harness 16, to the vibrational motors 25, the light emitting diodes 11, and the flexion sensors 20. The exemplary embodiment of the portable electronics can comprise a microprocessor 24, a serial communications circuit 29, an electrical power subsystem 30, a programming connection 31, a flexion sensor analog circuit 32, a light emitting diode control circuit 33, a vibrational motor control circuit 34, and/or status indicators 35.
An exemplary embodiment of a vibrational motor control circuit 34 can receive 3 volt regulated power and/or 5 volt unregulated power from the electrical power subsystem 30, potentially along with a pulse width modulated (PWM) signal, a square wave (SQW) clock signal, and/or five digital tactor enable (TEN) signals from the microprocessor 24. The PWM and/or SQW signals can be passed through an exclusive OR logic gate to provide a modified PWM that has a duty cycle that changes at the frequency of the SQW clock. The modified PWM signal can be provided to each of five vibrational motor driver chips (for example, the DRV8601 from Texas Instruments, Dallas, Tex.) potentially along with the five tactor enable (TEN) signals, which can enable the microprocessor 24 to activate any number or all of the vibrational motors 25. Wires within the wiring harness 16 can provide positive and/or negative leads connecting the vibrational motor control circuit 34 to the vibrational motors 25.
An exemplary embodiment of a light emitting diode control circuit 33 can receive 3 volt regulated power and/or 5 volt unregulated power from the electrical power subsystem 30, potentially along with a pulse width modulated (PWM) signal and/or two enable signals (EN1, EN2) from the microprocessor 24. The enable signals and/or the PWM signal can provide on/off and/or continuous dimming of the light emitting diodes 11 through an integrated circuit light emitting diode driver (for example, the LTC3453EUF from Linear Technology, Milpitas, Calif.). Six wires within the wiring harness 16 can provide positive and/or negative leads connecting the light emitting diode control circuit 33 to the light emitting diodes 11.
An exemplary embodiment of a flexion sensor analog circuit 32 can receive 3 volt regulated power from the electrical power subsystem 30, and/or a clock (SCL) signal and/or a data (SDA) signal from the microprocessor 24. The flexion sensor analog circuit 32 can contain five amplification circuits, each of which can comprise an operational amplifier, a digital potentiometer (for example, the MAX5479 from Maxim Incorporated, Sunnyvale, Calif.), resistors, and/or capacitors. The amplification circuits can generate a voltage that can vary when finger motion causes bending, and thus a change of resistance, in the flexion sensors 20. The SCL and/or SDA signals from an inter-integrated circuit (I2C) interface channel on the microprocessor 24 can adjust the resistance provided by each of the five digital potentiometers, and thus regulate the calibration (bias) voltage on the output of each amplification circuit. An analog-to-digital converter within the microprocessor 24 can receive the analog output voltage of each amplification circuit (F1A, F2A, F3A, F4A, and/or F5A). Ten wires within the wiring harness 16 can provide positive and/or negative leads connecting the flexion sensor analog circuit 32 to the flexion sensors 20.
An exemplary embodiment of an electrical power subsystem 30 can receive 5 volt power (VUSB) from a serial communications circuit 29 and/or an enable (EN) signal from the microprocessor 24. A super-capacitor (for example, the HS203F from Tecate Group, San Diego, Calif.) can provide electrical energy storage to permit the vibrational motor control circuit 34 to temporarily consume more than the steady state power available from VUSB, thus permitting a wider range of tactile effects. The super-capacitor can be controlled by a super-capacitor charger integrated circuit (for example, the LTC4425 from Linear Technology, Milpitas, Calif.), which can receive external power from VUSB and/or its enable (EN) signal from the microprocessor 24. The electrical power subsystem 30 can include a low-dropout regulator (for example, the TLV70033DCKT from Texas Instruments, Dallas, Tex.) to provide stable 3 volt power to other components in the portable electronics 14.
An exemplary embodiment of a serial communications circuit 29 can receive 5 volt power (VBUS), two data lines (D+, D−), a ground connection (GND), and/or a cable shield connection (SH) from the flexible cable 17. The communications circuit 29 can include signal conditioning and/or electrostatic discharge protection. The communications circuit 29 can provide 5 volt power (VUSB) to the electrical power subsystem 30 and/or two serial communications lines (DP, DN), and/or a disconnect detection line (DCN) to the microprocessor 24.
An exemplary embodiment of a programming connection 31 can comprise a connector that provides a programming and/or debugging interface to the microprocessor 24 through an Joint Test Action Group (JTAG) port
An exemplary embodiment of status indicators 35 can comprise seven, or any number, of light emitting diodes that can receive digital output (G0, R0, R1, R2, R3, R4, and/or R5) from the microprocessor 24 to indicate the on/off power status of the board, the on/off status of each of the five vibrational motors 25, and/or any other status or debugging information.
An exemplary embodiment of a microprocessor 24 (for example, the STM32F103V8 from STMicroelectronics, Geneva, Switzerland) can include a central processing unit (CPU), random access memory (RAM), non-volatile memory, digital input and/or output, built-in timers, integrated analog-to-digital conversion, serial communications, I2C communications, and/or a JTAG port for programming/debugging. Software uploaded to microprocessor 24 through the JTAG port of the programming connection 31 can be stored in non-volatile memory and/or, on power-up of the portable electronics 14, loaded into RAM and/or executed by the CPU.
Certain exemplary embodiments can provide mobile human-machine interface functionality similar to that provided by a keyboard and/or mouse for desktop computing. In operation, one can wear the gloves in a normal manner. The camera 13 can be positioned such that its field of view can extend outwards to provide its internal sensor with visibility to the light emitting diodes 11 on the back of the gloves. The flexible cable 17 and/or computing system 23 can be integrated in a comfortable manner within the fabric of an outer layer of clothing, held in place by fabric, stitching, hook-and-loop fastener, and/or by any other means, and/or, if applicable, integrated within other systems within a protective suit.
FIG. 11 is a software flow chart illustrating an exemplary processor-based human-machine interface process for exemplary protective gloves that provide keyboard and/or mouse capability using motion sensing transducers of hand position, motion sensing transducers of finger movement, and/or tactile sensory output transducers. The human-machine interface process can be driven by one or more hand position 36 and/or finger movement 43 inputs by a human operator and/or can produce sensory feedback to the human operator in the form of a tactile feedback display 49, a graphical display 42, and/or a character display 56. The flow can have one or a multitude of branches corresponding to the system mode 39 which can take one or more enumerated values including MOUSE and KEYBOARD.
The hand position tracking process 37 can observe hand position input 36 through the position and/or motion of any and/or each light emitting diodes 11 on the back of one or more outer gloves 12. The hand position tracking process 37 can utilize the processor to calculate the pixel location of each light emitting diode in a continuous stream of digital image frames generated by the camera 13 at a predetermined rate, which can be approximately 20 to approximately 120 frames per second, e.g., approximately 100 frames per second. Via the hand position tracking process 37, the processor can use the light emitting diode pixel locations to calculate the position and/or orientation of the outer glove 12 with respect to the camera 13. Knowledge of the position and/or orientation of the camera 13 can be used by the processor to calculate hand position data 38 representing the position and/or orientation of the outer glove 12 with respect to the user's torso, helmet, and/or any other object.
If the system mode 39 is MOUSE, hand position data 38 can be used by mouse position data processing 40 to determine cursor position, or a change in cursor position, on a two-dimensional graphical display 42. In certain exemplary embodiments, a change in hand position from a previous position can be used by a processor to calculate an incremental change in the pixel location of the cursor. The change in cursor pixel location can be encapsulated in mouse motion event data 41 that can be used by any application software and/or rendered through the graphical display 42.
To convert hand position data to cursor position, the processor can implement an algorithm such as that suggested by the following Java code segment:

    
    
        public void motionActionPerformed(HandMotionEvent event) {
        
            // only respond if we're in MOUSE mode
            if (systemMode==SystemMode.MOUSE) {
            // implement differential mode mouse using (x, y)
            // position from camera
            final double xs=event.getX( );
            final double ys=event.getY( );
            int dx=(int) (_xGain*(xs−_xLast));
            int dy=(int) (_yGain*(ys−_yLast));
            // prevent large jumps when tracked object pops in/out of view
            final int dmax=300;
            if (dx>dmax) {dx=0; dy=0;}
            
                else if (dx<−dmax) {dx=0; dy=0;}
                else if (dy>dmax) {dx=0; dy=0;}
                else if (dy<−dmax) {dx=0; dy=0;}
            
            
            // get current cursor location
            final Point location=MouseInfo.getPointerInfo( ).getLocation( );
            // increment cursor location by (dx, dy)
            mouseMove(location.x+dx, location.y+dy);
            // save previous object (x, y) position
            _xLast=xs;
            _yLast=ys;
            }
        
        
        }
    
    


The finger position tracking process 44 can observe finger movement input 43. Via the finger position tracking process 44, the processor can provide digitized data from each flexion sensor analog circuit 32 to a first order low pass filter to calculate finger position data 45 that is substantially free of high frequency noise. This low pass filter can be implemented with a cutoff frequency in the range of approximately 10 to approximately 100 (e.g., approximately 50) cycles per second. The finger position data 45 can thus represent the position of any or all digits with respect to one or both hands.
If the system mode 39 is MOUSE, finger position data 45 can be used by mouse gesture recognition process 46 to generate mouse button event data 47. Mouse button event data 47 can include user interface events that would normally be generated by a standard computer mouse in desktop computing, including, but not limited to, MOUSE_CLICK, MOUSE_DOUBLE_CLICK, MOUSE_DOWN, MOUSE_UP, and/or WHEEL_SCROLL for any or all buttons including LEFT, RIGHT, and/or MIDDLE, etc. The computing system 23 can interpret these mouse button events as if they were generated by a standard computer mouse.
The recognition of a finger tapping motion in the mouse gesture recognition process 46 can comprise: (1) estimation of individual finger speed as the change in finger position over a predetermined clock interval on the processor which can be in a range between approximately 0.1 and approximately 20 (e.g., approximately 1.0) milliseconds, (2) detection of a speed that exceeds a predetermined positive speed threshold (rising edge), and (3) a subsequent detection of a speed less than a predetermined negative speed threshold (falling edge, corresponding to an arresting motion). During the interval between detection of the rising and falling edge of an individual finger, the gesture recognition process can be suspended for all other fingers on the associated hand. This temporary suspension can prevent natural finger motion synergies (for example between the ring and pinky fingers) from generating erroneous events.
In certain exemplary embodiments, the mouse gesture recognition process 46 can utilize the thumb and/or any other finger or combination of fingers on either or both hands to drive LEFT mouse button events. A tapping motion of the digit(s) can generate a LEFT MOUSE_CLICK event. Two sequential tapping motions that occur for the same finger within a predetermined time interval, which can be between approximately 100 and approximately 1000 (e.g., approximately 300) milliseconds, can generate a LEFT MOUSE_DOUBLE_CLICK event. A continuous flexion of the digit(s) can generate a LEFT MOUSE_DOWN event, and/or reversal of the continuous flexion of the digit(s) can generate a LEFT MOUSE_UP event.
In certain exemplary embodiments, the mouse gesture recognition process 46 can utilize the index and/or any other finger or combination of fingers on either or both hands to drive RIGHT mouse button events. A tapping motion of the digit(s) can generate a RIGHT MOUSE_CLICK event. Two sequential tapping motions that occur for the same finger within a predetermined time interval, which can be between approximately 100 and approximately 1000 (e.g., approximately 300) milliseconds, can generate a RIGHT MOUSE_DOUBLE_CLICK event. A continuous flexion of the digit(s) can generate a RIGHT MOUSE_DOWN event, and/or reversal of the continuous flexion of the digit(s) can generate a RIGHT MOUSE_UP event.
In certain exemplary embodiments, the mouse gesture recognition process 46 can utilize the middle and/or any other finger or combination of fingers on either or both hands to drive MIDDLE mouse button events. A tapping motion of the digit(s) can generate a MIDDLE MOUSE_CLICK event. Two sequential tapping motions that occur for the same finger within a predetermined time interval, which can be between approximately 100 and approximately 1000 (e.g., approximately 300) milliseconds, can generate a MIDDLE MOUSE_DOUBLE_CLICK event. A continuous flexion of the digit(s) can generate a MIDDLE MOUSE_DOWN event, and/or reversal of the continuous flexion of the digit(s) can generate a MIDDLE MOUSE_UP event.
In certain exemplary embodiments, the mouse gesture recognition process 46 can utilize a simultaneous grasping (finger flexion) motion of the thumb and index finger or any other gesture involving any combination of fingers on either or both hands to drive WHEEL_SCROLL events. In certain exemplary embodiments, right hand gestures can be interpreted as forward (positive) WHEEL_SCROLL events and/or left hand gestures as backward (negative) WHEEL_SCROLL events.
In certain exemplary embodiments, tactile feedback processing 48 can generate tactile sensory waveforms, corresponding to mouse button event data 47, which can be rendered through a tactile feedback display 49. In certain exemplary embodiments, the tactile feedback display 49 can comprise a microprocessor 24, a vibrational motor control circuit 34, and/or one or more vibrational motors 25. In certain exemplary embodiments, tactile sensory waveforms can be applied to the finger or fingers associated with event generation. For example, for a LEFT MOUSE_CLICK event, tactile feedback processing 48 can generate a waveform (to a thumb aligned vibrational motor 25) consisting of two approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses of approximately 5 to approximately 50 (e.g., approximately 14) meters-per-second-squared amplitude, with approximately 10 to approximately 50 (e.g., approximately 25) millisecond pulse duration and/or approximately 10 to approximately 50 (e.g., approximately 25) millisecond inter-pulse delay. In a similar manner, MOUSE_DOWN and/or MOUSE_UP events can result in single approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses of approximately 10 to approximately 50 (e.g., approximately 14) meters-per-second-squared amplitude and/or approximately 10 to approximately 50 (e.g., approximately 25) millisecond duration to the corresponding finger. For MOUSE_DOUBLE_CLICK events, tactile feedback processing 48 can generate a waveform consisting of two MOUSE_CLICK tactile events, with an approximately 20 to approximately 100 (e.g., approximately 50) millisecond delay between the two. For WHEEL_SCROLL events, tactile feedback processing 48 can produce three approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses in the thumb and/or index finger aligned motors of approximately 5 to approximately 50 (e.g., approximately 7) meters-per-second-squared amplitude, with approximately 20 to approximately 80 (e.g., approximately 40) millisecond pulse duration and/or approximately 20 to approximately 80 (e.g., approximately 40) millisecond inter-pulse delay.
If the system mode 39 is KEYBOARD, finger position data 45 can be used by keyboard gesture recognition process 52 to generate finger press data 53. Keyboard event processing 54, can utilize the combination of finger press data 53 and the finger to key mapping 51, to generate key press events that can be used by any application software and/or rendered by one or more character displays 56 and/or graphical displays 42.
In certain exemplary embodiments, the keyboard gesture recognition process 52 can utilize finger position data 45 to recognize motions by one or more fingers or combinations of fingers. In certain exemplary embodiments, the keyboard gesture recognition process 52 can interpret a tapping motion by an individual finger as a key strike by that finger, encapsulated in finger press data 53. The keyboard gesture recognition process 52 can comprise: (1) estimation of individual finger speed as the change in finger position over a predetermined clock interval on the processor which can be in a range between approximately 0.1 and approximately 20 (e.g., approximately 1.0) milliseconds, (2) detection of a speed that exceeds a predetermined positive speed threshold (rising edge), and (3) a subsequent detection of a speed less than a predetermined negative speed threshold (falling edge, corresponding to an arresting motion). During the interval between detection of the rising and falling edge of an individual finger, the gesture recognition process can be suspended for all other fingers on the associated hand. This temporary suspension can prevent natural finger motion synergies (for example between the ring and pinky fingers) from generating erroneous key strikes.
If the system mode 39 is KEYBOARD, motion sensing transducers of hand position, motion sensing transducers of finger movement, and/or tactile sensory output transducers can be used to enable virtual touch typing by the person wearing protective gloves. In certain exemplary embodiments, hand position data 38 can be used by keyboard position data processing 50 to generate finger to key mapping data 51. Finger to key mapping data 51 can associate each of one or more fingers on each hand with a keyboard character on a virtual keyboard. In certain exemplary embodiments, keyboard position data processing 50 can emulate a QWERTY keyboard. In certain exemplary embodiments, keyboard position data processing 50 can use a grid arrangement (as shown in FIG. 12) to assign keys to fingers based on the projection of hand position data 38 onto the two-dimensional grid. When entering KEYBOARD mode, the current left and/or right hand position can become “home” position. In this case (which is illustrated in FIG. 12) four fingers on either and/or each hand can be mapped to keys in the center of the virtual board, with the thumbs on each hand mapped to the space bar. In this home position, consistent with a conventional keyboard, the four (non-thumb) fingers of the left hand can be mapped to the characters “a,” “s,” “d,” and/or “f” and/or the fingers on the right hand to “j,” “k,” “l,” and/or “;”. From this home position, keyboard position data processing 50 can permit the user to access other keys through short hand movements to other grid positions. In certain exemplary embodiments, an approximately 3×4 grid can be assigned to the left hand and/or an approximately 5×4 grid can be assigned to the right hand (as shown in FIG. 12) providing access to an entire QWERTY keyboard layout. FIG. 13 illustrates an exemplary use of this method to type out the phrase “Hello!” using a combination of hand motion and the following key strike finger gesture sequence: (1) left pinky, (2) right index, (3) left middle, (4) right ring, (5) right ring, (6) right ring, (7) right pinky, and/or (8) left pinky.
To convert hand position data 38 to finger to key mapping data 51, the processor can implement an algorithm such as that suggested by the following Java code segment:

The flow chart in FIG. 11 illustrates that in certain exemplary embodiments, tactile feedback processing 48 can generate tactile sensory waveforms, rendered through a tactile feedback display 49, to inform the user of a new hand position on the virtual keyboard. When a change in hand position 36 results in new finger to key mapping data 51, a tactile sensory waveform (rendered through a tactile feedback display 49) can signal the new mapping. In certain exemplary embodiments, the tactile sensory waveform can consist of two approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses of approximately 5 to approximately 50 (e.g., approximately 7) meters-per-second-squared amplitude applied to all five fingers; with approximately 10 to approximately 50 (e.g., approximately 25) millisecond pulse duration and/or approximately 10 to approximately 50 (e.g., approximately 25) millisecond inter-pulse delay. In certain exemplary embodiments, hand movement back to the home position can be signaled by a unique tactile sensory waveform which can consist of three approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses of approximately 5 to approximately 50 (e.g., approximately 7) meters-per-second-squared amplitude applied to all five fingers; with approximately 10 to approximately 50 (e.g., approximately 25) millisecond pulse duration and/or approximately 10 to approximately 50 (e.g., approximately 25) millisecond inter-pulse delay.
In certain exemplary embodiments, tactile feedback processing 48 can generate tactile sensory waveforms, rendered through a tactile feedback display 49, to confirm that finger press data 53 has been generated by keyboard gesture recognition 52. In certain exemplary embodiments, tactile feedback processing 48 can generate a tactile sensory waveform (rendered through a tactile feedback display 49) to the individual finger associated with the finger press data 53. In certain exemplary embodiments, the tactile sensory waveform can consist of two approximately 50 to approximately 300 (e.g., approximately 175) cycles-per-second square-wave pulses of approximately 5 to approximately 50 (e.g., approximately 14) meters-per-second-squared amplitude, with approximately 10 to approximately 50 (e.g., approximately 25) millisecond pulse duration and/or approximately 10 to approximately 50 (e.g., approximately 25) millisecond inter-pulse delay.
FIG. 1 shows an exemplary embodiment with three light emitting diodes 11 on the exterior of a glove 12. Three light emitting diodes can create a triad that can be tracked by a camera 13 as a rigid body. In this embodiment, the computing system 23 can calculate up to three-dimensional position coordinates (x, y, and/or z) for either and/or each triad as well as its orientation (roll, pitch, and/or yaw). This additional information can be used by the computing system 22 to create a richer set of user interactions in application software. User interactions can include manipulating software objects with three-dimensional geometry, designating points on a three-dimensional map display, providing control inputs to a robotic manipulator, and/or orienting hand position with respect to a three-dimensional virtual keyboard.
In certain exemplary embodiments, the human-machine interface can comprise both left and right gloves. However, certain alternate embodiments can include only a single left or right hand glove. FIG. 14 shows a human-machine interface with a single right hand glove. This single hand embodiment can enable a full mouse emulation mode and/or a modified keyboard emulation mode. In this single-handed keyboard emulation mode, a distinct set of finger gestures (such as a simultaneous four finger tapping motion) can switch the finger-to-key mapping between the right and left side of the keyboard. In this way a single hand can access the entire set of keys.
FIG. 14 shows that in certain exemplary embodiments, a single or reduced number of light emitting diodes 11 may be placed on the back of the hand. In the case of a single light emitting diode 11, the image stream from the camera 13 can be used by the computing system 23 to calculate position coordinates (x, y, and/or z) of the glove with respect to the camera 13.
FIG. 15 shows a perspective view of the interior of an exemplary embodiment of the glove in FIG. 14. In certain exemplary embodiments, a single or reduced number of tactile actuation assemblies 15, light-emitting diodes 11, and/or flexion sensors 20 can be preferable in applications where low cost and/or simplicity are desired. Conversely, in applications where high fidelity sensing and/or tactile feedback performance are desired, a greater number of tactile actuation assemblies 15, light-emitting diodes 11, and/or flexion sensors 20 can be preferable.
FIG. 16 shows an exemplary embodiment of a tactile actuation assembly 15 in which a vibrational motor 25, which can be of linear resonant actuator type or any alternative type, can move with respect to a tactile adapter 26 in which it is partially enclosed.
FIG. 17 shows an exploded view of the exemplary embodiment of the tactile actuation assembly 15 shown in FIG. 16. Flexible gaskets 27 can provide a spring-like resistance to the oscillatory motion of the vibrational motor 25 within the tactile adapter 26. Flexible gaskets 27, which can be fabricated from rubber, foam, and/or metal, can provide desired force versus displacement (spring stiffness) and/or desired force versus velocity relationship (damping) properties. These properties can be selected to promote the efficient conversion of electrical energy (applied by portable electronics 14 to the vibrational motor 25) into mechanical vibrations on the surface of the human finger.
FIG. 18 shows a top view of the exemplary tactile actuation assembly 15 shown in FIG. 16 and identifies section C-C used in FIG. 19.
FIG. 19 shows a section view, taken at section C-C, of the exemplary tactile actuation assembly 15 shown in FIG. 18. Flexible gaskets 27 can be placed above and/or below the vibrational motor 25 such that the relative motion of the vibrational motor 25 with respect to the tactile adapter 26 is subject to the stiffness and/or damping properties of the flexible gaskets 27.
FIG. 20 shows a section view taken at section “A-A” of FIG. 2 for the exemplary embodiment of the tactile actuation assembly 15 shown in FIG. 16. In certain exemplary embodiments, such as a space suit, the gas within the pressure layer of the inner glove 21 can be maintained such that it exerts a greater pressure on the pressure layer than that exerted by the outside environment. In such cases, the inner glove layers can become stiffened, similar to the surface of an inflated balloon. As a result the glove material can become an efficient carrier of mechanical vibrations. The tactile adapter 26 can be operatively attached to the fabric of the inner glove 21. A linear resonant actuator type vibrational motor 25 can be held within a tactile adapter 26 such that its motion is limited to a direction normal to the surface of the inner glove 21. An amplitude-modulated drive voltage can be applied to the motor from the portable electronics 14 through the wiring harness 16. The resulting oscillatory forces in the vibrational motor 25 can cause it to push against the adjacent flexible gaskets 27. On the downward stroke of the vibrational motor 25, the flexible gasket 27 between the vibrational motor 25 and the inner glove 21 pushes against the material of the inner glove 21. On the upward stroke of the vibrational motor 25, the flexible gasket 27 between the vibrational motor 25 and the tactile adapter 26 pushes against the tactile adapter 26. The tactile adapter 26, in turn, pulls against the material of the inner glove 21. These oscillatory push/pull forces against material of the inner glove 21 generate vibrations (oscillatory displacements) in the inner glove 21 that carry around the pressure-stiffened material to the human finger 28. The mechanical vibrations, induced by oscillations of the inner glove 21 against the human finger 28, result in perceptible tactile sensation. The stiffness and/or damping of the flexible gaskets 27 can be selected (experimentally or analytically) to improve the transfer of electrical energy from the portable electronics 14 to mechanical energy in vibrations at the human fingertip.
Certain exemplary embodiments can require the availability of an electrical power and/or data connection to the gloves. Of note, space suits used by NASA typically have a power harness for glove fingertip heaters that can be modified to provide a power and/or data conduit for the gloves.

        logic gate—a physical device adapted to perform a logical operation on one or more logic inputs and to produce a single logic output, which is manifested physically. Because the output is also a logic-level value, an output of one logic gate can connect to the input of one or more other logic gates, and via such combinations, complex operations can be performed. The logic normally performed is Boolean logic and is most commonly found in digital circuits. The most common implementations of logic gates are based on electronics using resistors, transistors, and/or diodes, and such implementations often appear in large arrays in the form of integrated circuits (a.k.a., IC's, microcircuits, microchips, silicon chips, and/or chips). It is possible, however, to create logic gates that operate based on vacuum tubes, electromagnetics (e.g., relays), mechanics (e.g., gears), fluidics, optics, chemical reactions, and/or DNA, including on a molecular scale. Each electronically-implemented logic gate typically has two inputs and one output, each having a logic level or state typically physically represented by a voltage. At any given moment, every terminal is in one of the two binary logic states (“false” (a.k.a., “low” or “0”) or “true” (a.k.a., “high” or “1”), represented by different voltage levels, yet the logic state of a terminal can, and generally does, change often, as the circuit processes data. Thus, each electronic logic gate typically requires power so that it can source and/or sink currents to achieve the correct output voltage. Typically, machine-implementable instructions are ultimately encoded into binary values of “0”s and/or “1”s and, are typically written into and/or onto a memory device, such as a “register”, which records the binary value as a change in a physical property of the memory device, such as a change in voltage, current, charge, phase, pressure, weight, height, tension, level, gap, position, velocity, momentum, force, temperature, polarity, magnetic field, magnetic force, magnetic orientation, reflectivity, molecular linkage, molecular weight, etc. An exemplary register might store a value of “01101100”, which encodes a total of 8 “bits” (one byte), where each value of either “0” or “1” is called a “bit” (and 8 bits are collectively called a “byte”). Note that because a binary bit can only have one of two different values (either “0” or “1”), any physical medium capable of switching between two saturated states can be used to represent a bit. Therefore, any physical system capable of representing binary bits is able to represent numerical quantities, and potentially can manipulate those numbers via particular encoded machine-implementable instructions. This is one of the basic concepts underlying digital computing. At the register and/or gate level, a computer does not treat these “0”s and “1”s as numbers per se, but typically as voltage levels (in the case of an electronically-implemented computer), for example, a high voltage of approximately +3 volts might represent a “1” or “logical true” and a low voltage of approximately 0 volts might represent a “0” or “logical false” (or vice versa, depending on how the circuitry is designed). These high and low voltages (or other physical properties, depending on the nature of the implementation) are typically fed into a series of logic gates, which in turn, through the correct logic design, produce the physical and logical results specified by the particular encoded machine-implementable instructions. For example, if the encoding request a calculation, the logic gates might add the first two bits of the encoding together, produce a result “1” (“0”+“1”=“1”), and then write this result into another register for subsequent retrieval and reading. Or, if the encoding is a request for some kind of service, the logic gates might in turn access or write into some other registers which would in turn trigger other logic gates to initiate the requested service.

        machine-implementable instructions—directions adapted to cause a machine, such as an information device, to perform one or more particular activities, operations, and/or functions via forming a particular physical circuit.
