The jury is still out regarding whether this particular project is ahead of its time and current technology is not yet capable, making it difficult for even highly skilled individuals or groups to accomplish.
The string of unsuccessful contractors chosen to work on this project has grown to an uncounted number now, with some never able to understand the basics of the project despite repeated explanations, others seeming to initially understand it but then showing that it is obviously beyond their skill set when getting into the project, while still others seem to be able to understand it well but then simply stop communicating for whatever their reason(s). Most of whatever budget I had earlier has been depleted due to these unqualified contractors as a whole.
This is a project that (in my opinion) could and should be competently accomplished in mere weeks and relatively cheaply by an appropriately skilled individual or group (at least for an adequately performing prototype using off-the-shelf parts to start). And time is of the essence due to a very rapidly dwindling patent protection period.
This is a golf-related project that the industry needs very badly at this point in order to prevent the clubfitting trade from continuing its horrible and embarrassing performance record and reputation. Some knowledge of and/or interest in golf and the game's future might be a plus, but is not required and could actually hurt the project due to so much deeply embedded incorrect knowledge within the golf industry.
This device(s) and application comprise first accurately tracking and logging golf club movement data before any part of a golf swing (even a practice swing) is even begun (the pre-swing period). While the use of a wireless inertial-type sensor(s) attached to a golf club might at first thought seem most appropriate, sensor drift and noise have been very problematic to this point, so a video camera or other system or technology type has surely not been ruled out. A selected part(s) of the acquired data then needs to be processed through an appropriate algorithm(s) to determine a rotation point location that is developed along the length of the club and that can be in notably different locations from golfer to golfer even using the same golf club.
Help is needed in areas including hardware selection and/or development, software application development, and algorithm development, with adequate hardware for logging adequate data seeming to be needed before much software development can proceed (though I could be wrong about this). A prototype with which to gather critical foundational testing data for early analysis is first required in the shortest time possible time and at minimal expense before the project can proceed further. If making a quote, please note whether you are a specialist desiring to contribute to any one particular skill described or whether you consider yourself qualified to develop multiple aspects of the project.
Though very crudely produced rather quickly recently, a homemade requirements document detailing various elements of the project and experiences to date is attached for inspection if desired. (Also available for inspection if desired is the manual produced by the first contractor for the sensor hardware he developed). Initially browsing through just the images and videos linked through the document might help one to understand the fundamentals of the project, with additional details in the text as desired.
Anyone interested, able, and willing to skillfully help finally bring any part(s) of this particular project to fruition in as little time and cost as possible please consider contacting me with any additional questions or comments. With other leading edge projects beyond this one already in early development (and further improvements in this project expected over time), the potential exists for a longer-term relationship if desired. I am open to fixed-price or hourly quotes. Thanks.
