I please need the following hardware/software analysis device/application developed, which operates pretty much as it is named, which is a “Golf Grip Hand Structure Efficiency Device.”
As envisioned at this time, there will be two small wireless sensors, perhaps 9DOF absolute orientation sensors, one attached to the back side of each hand of a golfer, essentially opposite of yet equivalent to the palms.
The two sensors and needed software would track the orientations of the hands via sensor data, completely independently of each other. Logging and displaying this orientation data, along with mathematically computing the orientation differences of the hands relative to each other over time and a swing, are the base core functions of the device and application.
A simplest user interface would only need to be a visual representation of a pair of hands (might initially be just a pair of line vectors) basically centered on a display that accurately depicts the orientation data of the sensors over the time and course of a swing. Mathematical information will also be displayed regarding 3D sensor orientation values of the hands, both independently and relative to each other, with respect to time and the swing. An important feature for a user to optionally implement is a tare or similar software function that electronically aligns the sensors in the same direction and essentially through the center of the hands at the start of a golf swing. This would make certain analyses more convenient and easier to comprehend.
From this foundational interface, additional yet still very basic functions are also needed to be able to directly compare the data described above for at least two swing specimens essentially side by side. One specimen can be that of baseline or reference swing data for a golfer, while one or more other specimens can be of the golfer's swing data under a different prescribed condition(s). The data from the multiple specimens need to be compared mathematically and visually. The results of such comparisons need to be displayed for a user to gain the needed solution(s).
Analysis implementations can be side-by-side comparisons and/or overlaid comparisons as just two examples, and I am open to either or other alternatives. Different swing specimens need to be synced to each other as well as possible for accurate comparisons, and specimens must be visually rotatable or otherwise comparable in 3D on the display in order to observe hand orientation values along different planes of space.
Other possible added features might be beneficial. With an orientation-only rudimental base, an actual video of a golfer can be taken while swinging and while sensor data is simultaneously gathered. The video and sensor orientation specimens can then be synced up with each other on a display. So instead of having just a pair of hand orientations on a display to reference, a user can also reference the video and better see exactly where during the swing the hand orientations are what they are for the golfer.
Or, if the hardware and/or software are capable enough, acquired sensor data alone might be used to show and analyze not just the orientations of the hands that are otherwise not traveling anywhere on a display, but to also track and display the 3D movements and locations of the hands as they actually travel around over the course of a swing.
Off-the-shelf hardware development orientation sensors are expected to be used first to get an initial prototype in hand less expensively and more quickly to evaluate. But such sensors can still have varying specifications, so appropriate hardware knowledge to help choose the best sensors (based on the above description of operation) would seemingly be helpful in order to best proceed. Certain decisions have not been conclusively decided yet, such as whether the application will comprise a desktop and/or phone application for example.
Hourly or project proposals can be considered. Thank you.
