Sage Casting Analyzer Software System

SAGE Casting Analyzer Developed at MKP

Learning to fly cast well is the greatest bottleneck in advancing in the sport of fly fishing. Fly fishers frequently employ fly casting instructors, read books, watch videos, or attend private fly casting schools in order to improve their casting skills. All fly casting instruction today is qualitative and rests on the ability of the instructor or student to critique casts using visual observations of the motion of the fly rod and line, sometimes with the aid of video capture and playback. The fly casting coach/analyzer sold by Sage is about to change all that. The invention by Noel Perkins, a professor of mechanical engineering at the University of Michigan, provides quantitative measurements of the fly casting stroke and automatically deduces coaching tips. The core hardware includes a MEMS angular rate gyro mounted on the fly rod that measures the angular velocity of the fly rod in the plane of the fly cast. The angular velocity of the fly rod represents approximately 90% of the input given to the fly rod by the fly caster. This signal, often called the fly casting “signature,” is captured and stored on a hand-held computer (PDA) using a miniature A/D converter that communicates through the PDA hotsynch cable. Research studies of the casting signatures have revealed the key metrics that distinguish casting skill levels and common casting problems. Sage wants to develop a fly cast analysis software so that it can run on a PC (Windows and Mac). The software automatically evaluates these metrics for instantaneous feedback to the fly caster. The general requirements of the new PC software are as follows:

  1. Ability to read the .pdb files and to create a simple data base of these files for later access by the user.
  2. To reproduce current fly casting analysis algorithms.
  3. To automatically create attractive graphics and tables.
  4. To automatically format a printable “report” which exports the graphics and tables into a standard document (e.g., PDF document).
  5. Make all of these functions as simple to use as possible by providing a GUI that allows the user to navigate the software, to select data files to analyze, and to print results.

MKP helped SAGE and Professor Noel Perkins to achieve the above goals, which resulted in the commercial product shown in below.
