I. Field
The following description relates generally to computer science, and more particularly to method and apparatus for scaling gesture recognition to physical dimensions of a user.
II. Background
Some computer processing systems utilize gesture recognition as user input by interpreting human gestures. Typically, gestures originate from human body motion, such as hand gestures. User gesture input has grown in popularity as an alternative to established touch, pointing device, and speech input techniques.
Some conventional gesture recognition techniques utilize mechanical devices, such as accelerometers, to determine body motion and movement. However, problems arise in conventional systems that use mechanical devices for user gesture input when a necessary body motion or movement other than the hand is needed. For example, in conventional systems that rely heavily on accelerometers, the total gesture movement affects the output less than the point of maximum acceleration. Depending on position of the gesture, the distance traveled by the accelerometer is considered less important than the acceleration of the gesture. Thus, the accuracy of accelerometers for gesture input is reduced by the limited interpretation of body movement.
Interpretation of body movement may be improved if physical dimensions may be used along with sensor information. Thus, it would be desirable to be able to improve the accuracy of gesture input based on such physical dimensions as the physical dimensions of a user.
The following presents a simplified summary of one or more aspects of methods and apparatuses to provide a basic understanding of such methods and apparatuses.

Several aspects of this disclosure will now be presented with reference to
User gestures may originate from any user body motion, movement, and/or pose, and user gestures include full body motion, movement, and/or pose and any body part motion, movement, and/or pose. For example, user gestures may include hand movements (e.g., punch, chop, lift, etc.), foot movements (e.g., kick, knee bend, etc.), head movements (e.g., head shake, nod, etc.), and/or body movements (e.g., jumping, kneeling, lying down, etc.).
The remote system 104 may be any suitable system capable of communicating with the apparatus 102 to support gesture recognition functionality. In at least one aspect, the remote system 104 may be configured to provide at least one input for gesture scaling by the apparatus 102 to improve the gesture accuracy of the user during the operation of the apparatus 102. By way of example, the gesture input required by a user to trigger an action or enter a command may be scaled based on at least one physical dimension of the user with the remote system 104. Various configurations of the remote system 104 to provide gesture scaling will be described in greater detail herein.
Referring to
In one implementation of the remote system 104, one or more sensors may be utilized and configured to provide one or more signals to the apparatus 102. Generally, a sensor is a device configured to measure or capture a physical quantity (e.g., motion, movement, acceleration, orientation, distance, range, height, length, etc.) and convert the physical quantity into a signal that can be transmitted to and processed by the apparatus 102. The one or more sensors may comprise one or more remote accelerometers, remote ranging sensors, remote gyros, or any other suitable sensor, or any combination thereof.
In another implementation of the remote system 104, a belt or harness may be utilized. The belt or harness may be wearable by a user. The belt or harness may include one or more sensors for measuring or capturing a physical dimension of the user and/or a movement by the user to determine a gesture of the user without regard to the location of the user relative to the apparatus 102. The one or more sensors may comprise one or more remote accelerometers, remote ranging sensors, remote gyros, or any other suitable sensor, or any combination thereof.
In another implementation of the remote system 104, a mat or platform may be utilized. The mat or platform may be positioned on the ground to establish ground level relative to a user. The mat or platform may include one or more sensors for capturing a physical dimension of the user and/or a movement by the user to determine a gesture of the user without regard to the location of the user relative to the apparatus 102. The mat or platform may be stationary or moveable to achieve various degrees of freedom. The one or more sensors may comprise one or more remote accelerometers, remote ranging sensors, remote gyros, or any other suitable sensor, or any combination thereof.
Referring to
In one implementation of the system 104, each remote node 1061, 1062, . . . , 106n comprises at least one remote sensor configured to provide at least one signal to the apparatus 102. Each remote sensor is configured to measure or capture a physical quantity (e.g., motion, movement, acceleration, orientation, distance, range, height, length, etc.) and convert the physical quantity into at least one signal that can be transmitted to and processed by the apparatus 102. Each remote sensor comprises at least one of a remote accelerometer, a remote ranging sensor, and a remote gyro.
Scaling refers to a linear transformation that alters (i.e., increases or decreases) the reference size of an object or objects by a scale factor that may be similar in all directions. For example, two objects of the same height may be positioned at different distances from a reference point. From the view of the reference point, the object positioned at a greater distance from the reference point may appear smaller, even though the objects are of the same height. Thus, knowing the distance of each object from the reference point and each object's height provides a way to scale the objects in a uniform manner to be judged as the same height without regard of each objects position with respect to the reference point.
The apparatus 102 may be used for scaling gesture recognition to physical dimensions of a user. As described herein, the apparatus 102 is configured to obtain at least one physical dimension of a user and determine a gesture of the user based on the at least one physical dimension without regard to the location of the user relative to the apparatus 102.
For example, in one implementation of the apparatus 102, a user may provide gesture input for triggering an action or entering a command may be scaled significantly different for users that vary in physical dimensions, such as height, arm span, etc. For instance, two different users, such as an adult and a child, may attempt to enter a similar command using a gesture input and the necessary movement may be too large for the child or too small for the adult. Therefore, gesture scaling may improve accuracy of user gesture input.
The apparatus 102 may achieve gesture scaling by obtaining or determining at least one physical dimension of the user. The at least one physical dimension of the user may include height of the user, arm span of the user, height of a handheld device held at a neutral position, such as arms at the user's side. In some instances, accuracy of a scaling may vary depending on which physical dimension is selected or how calculated if not directly inputted by the user.
In one implementation of the apparatus 102, a physical dimension of a user may be determined by direct user input via a user interface device, such as a handheld device. For example, prompting the user to enter height or length of arm span may provide an accurate representation of scaling necessary for accurate interpretation of gesture input by the user.
In another implementation of the apparatus 102, a physical dimension of a user may be determined by utilizing a system 104 of sensors and prompting user movement. For example, the user may be prompted to touch a body part, such as the user's head, and then touch a baseline reference point, such as the ground, with a handheld device having a mechanical sensing device, such as an accelerometer, gyro, etc. The system 104 of sensors may be configured to identify and record starts and/or stops in movement followed by large movements to be a distance from head to ground. This learning technique may provide an approximation of height as different users may move the device from head to the ground in different manners. Some users may move the handheld device a shortest possible distance, and some users may move the handheld device a longer distance from head to ground.
In another implementation of the apparatus 102, a physical dimension of a user may be determined by utilizing a system 104 of ranging sensors with known physical dimensions, such as height, paired with prompted user movement. For example, if a user stands on a sensing mat having one or more ranging sensors with known height of zero and the user is then prompted to touch their head with a handheld device having a ranging sensor, the height of the user may be calculated in an accurate manner. Height and other physical dimensions may be calculated accurately when the system 104 of multiple ranging sensors (e.g., two or more ranging sensors) is utilized in combination with prompted movement with a handheld device. Alternatively, the system 104 of multiple ranging sensors may include two or more ranging sensors, and/or the system 104 of multiple ranging sensors may or may not be worn or held by the user.
In one implementation of the apparatus 102, user gestures may be obtained and/or determined based on at least one physical dimension of the user and an identified movement, wherein determining a gesture includes calibration of scale based on a relationship between the at least one physical dimension and the at least one movement of the user. This relationship may be defined in a lookup table or calculated by an equation. The apparatus 102 may be configured to improve accuracy of gesture scaling through a learning algorithm that accesses a history of movements performed by the user and adjusts an initial scaling that may be based on the at least one physical dimension. Information related to user physical dimensions, user movements, scaling, calibration of scale, any and all relationships between user physical dimensions and user movements, and history of user physical dimensions and user movements may be stored as part of a computer readable medium.
In another implementation of the apparatus 102, gesture recognition may be scaled to one or more physical dimensions of a user by selectively adjusting movements for particular inputs and/or commands to any physical dimension of the user. Properly adjusted movement parameters may provide an improved gesture input experience for users, may add an element of fairness to gaming applications, may reduce a risk of body strain when stretching farther than a natural range of movement for a user (e.g., forced adaptation of undersized users to large scale reference points), and may reduce the amount of attention necessary for satisfying user parameters when movement is confined to an unnaturally narrow range (e.g., forced adaptation of oversized users to small scale reference points). Information related to user movement parameters along with user physical dimensions, user movements, scaling, calibration of scale, any and all relationships between user physical dimensions and user movements, and history of user physical dimensions and user movements may be stored as part of a computer readable medium.
