Problems solved by technology

However, the MET model is task-specific, and thus the running game is built on the running-specific MET model, which can only be applied to running
The disadvantage of task-specific schemes is that many movements in computer games are "non-standard activities" and no MET model exists for these activities
Furthermore, custom designing MET models for these activities would be prohibitively expensive and would consume significant development time
For this reason, most computer games fail to provide MET values ​​or calorie output estimates for such non-standard activities, frustrating budding computer-based exercise

Embodiment Construction

[0011] Aspects of the invention will now be described by way of example and with reference to the above-listed embodiments as shown.

[0012] figure 1 An exemplary 3D interaction space 100 in which a user 10 is located is shown. figure 1 Also shown is gaming system 12, which may enable user 10 to interact with a video game. Gaming system 102 may be used to play a variety of different games, play one or more different media types, and / or control or manipulate non-gaming applications and / or operating systems. Gaming system 12 may include a game console 14 and a display device 16 that may be used to present game visuals to a game player. Gaming system 12 is a computing device, the details of which will be referred to Figure 5 be described.

[0013] back to figure 1 , the 3D interactive space 100 may also include a capture device 18 , such as a camera, which may be coupled to the game system 12 . The capture device 18 may be, for example, a depth camera for observing the 3D...

Abstract

A method for estimating a metabolic equivalent of task for use with a computing device is provided herein. The method includes receiving input from a capture device of a user; and tracking a position of each of the plurality of joints of the user. The method further includes determining a distance traveled for each of the plurality of joints between a first frame and a second frame; and calculating a horizontal velocity and a vertical velocity for each of the plurality of joints based on the distance traveled and an elapsed time between the first and second frames. The method further includes estimating a value for the metabolic equivalent of task using a metabolic equation including a component for the horizontal velocity and a component for the vertical velocity for each of the plurality of joints; and outputting the value for display.

Description

technical field [0001] The present invention relates to the calculation of metabolic equivalents using a computing device. Background technique [0002] Computer gaming systems have evolved to include more physically demanding activities, especially computer gaming systems equipped with natural input devices such as depth cameras. As a result, gaming has become some form of exercise for some users. However, these users have difficulty figuring out precisely how severe a workout was, such as how many calories a particular workout has burned. One prior approach can be found in computer games designed to simulate running. The running game displays to the user the Metabolic Equivalent of Task (MET) of the running activity, which can be used to determine the calories burned. However, the MET model is task-specific, and thus the running game is built on the running-specific MET model, which can only be applied to running. The disadvantage of the task-specific approach is that ...
