I am having a second thought on the beauty contest. I think it is better to have a Service Fault Call App Writing Competition (or SEFAUCAW) instead. There are many badminton fans all over the world who can write Android apps. The winner of the SEFAUCAW competition gets US$5000, the first runner-up $3000 and the second runner-up $1000. After BWF have selected the right app, they then ask the smartphone company to sponsor the hardwares. How about that?
Methinks, all the six points should be awarded to you. That is, pcll99 6 : 0 BWF No seriously, these could easily be implemented at club-level to find how feasible it is to do simple stuff. For starters, set your mobile during one of those club scrimmages on a fixed stand, and set it to record, or live stream on large overhead display courtside. No need for any app at this 'pilot' stage, as you can place a ribbon/string on the display at the legal service height. If your club is willing to let you do this, you can scale-up the technique when approaching local or regional tournament organisers, sponsors, or venture capitalists. You would find how easy, or difficult, it is. Report here with your findings and observations.
thanks @whatsthecallUmp (a) I don't have those slow-mo smartphones. They can record video at 240fps. Samsung S9, S10, S20 and later can shoot those videos. (b) It would be great if people with Samsung S9, S10, S20 or later can record videos while people are serving, in a variety of contexts (eg, forehand, backhand, singles, mixed doubles). Post them here. (c) As for casting your phone to a TV or laptop, should we use miracast, chromecast or something else? over Wifi, over LAN, over USB cable? (d) I think you need a pair of bluetooth keyboard and mouse to control the smartphone; I don't think you should handle your smartphone with your hands while it is recording in slow motion. (e) can the laptop record and instant replay the video? (f) can the laptop instant replay in slow motion? thanks.
Why can't we use this? (Or an invisible one that only shows up on camera). If the line hits the shuttle before striking it's pretty visible.
Light in infrared range shows up on most cameras, but is invisible for human eyes. But for club use it could be a normal visible one that has a switch to turn off after the serve.
thanks. or use a pair of blinkers, covering both sides of the laser level, like horse's blinkers. so that the laser beam appearing on the player's jersey is very narrowly focused on him or her only.
Apple Vision Pro seems feasible. it can understand gestures. how about other Mixed Reality or Augmented Reality glasses / headsets?
i found a few solutions for gesture recognition: (a) MediaPipe, gesture recognition for Android https://developers.google.com/mediapipe/solutions/vision/gesture_recognizer/android https://github.com/google/mediapipe (b) Astra S Somatosensory Depth Camera Face/Gesture Recognition ROS Robot Eyes 3D Scanner VR/AR Sensor Module [for Android, Linux and Windows PC] https://www.amazon.com/GFTVRCE-Somatosensory-Gesture-Recognition-Scanner/dp/B0C2H4QL5F/ https://shop.orbbec3d.com/Astra-S https://shop.orbbec3d.com/camera some of these cameras work with Windows, Linux, Android and nvidia jetson (c) Arduino is also possible https://www.amazon.com/Arduino-Kinect-Projects-Design-Technology/dp/1430241675/
No kidding! I I'd even suggest that any mobile phone that's found to have their flash on during the matches would automatically have their phone confiscated for the duration of the tournament! Such a stupid annoyance! As if their puny flash will even light up their photo or video subject from 200 ft away !? Sent from my SM-S918W using Tapatalk
