proposal
A basketball free throw cannot yet be analyzed in real time by an individual practicing alone. One can try different things to attain different results (or even record their attempts), but this process is slow and unscientific. We would like to change this.

Our free throw feedback device would alert the user to their issues in real time based on a history of their made shots. In the training phase, it would gather data via 2-3 lower and upper body sensors to determine the averages forces applied by various parts of an individual’s body in a successful shot. The running averages would be calculated by transferring the data of each sensor to a computer for each attempt. Then, in the testing phase, the machine would either present an acknowledgement of a made shot, or constructive criticism to improve next time. The criticism would be based on which of these 2-3 sensors displayed the largest deviation from it’s average during the training phase. An example message from the machine might read, “More legs next time!”.

The hardware would essentially be the sensors (likely an array of accelerometers) fed to a microcontroller with several UART ports (for simultaneous data transfer) and power circuits to power each of them. The microcontroller would then transfer the data to the computer where a script would perform the higher level functions (running average, training vs. testing, and feedback).

Our project is an innovation in that it combines existing technologies (sensors/microcontroller/computer) with our data compilation and transferring for rewarding user experience. A potential competitor is the ESPN series “Sport Science” which analyzes performance in various sports, including basketball. It appears to be largely reactive while our device is proactive in that in is helping an individual in real time.

Laser Harp MIDI Controller with Musical Articulations

Featured Project

Electronic music concerts usually need eye-catching visual aids to create a certain atmosphere. Laser musical instruments is a great way to do this. We have been thinking of this project for a while and it was ECE445 that made this laser harp come true. The novelty of this project is that the harp-like laser device mainly focuses on playing articulations with laser and sensors, as a true universal MIDI controller, to control timbres that are synthesized or sampled. Articulations include piano/forte, vibrato, tremolo, and portamento. With the help of Professors and TAs, we learned how to pick right the components, design PCB, soldering, and program microcontroller. Those skills are not only useful in this class but also really important to electrical engineers. Also, we learned how to use individual strengths, combined with effective teamwork, in the pursuit of meaningful goals.
