(Portland, OR)  --  Sight impaired basketball fans are experiencing NBA games in a partnership with the Portland Trail Blazers.  OneCourt, based in Seattle, developed a device that allows sight impaired people to experience a basketball game by feel through their hands.  They place their hands on a device that lays on their lap.  Vibrations indicate where the play is on the court.  The two organizations worked with local nonprofits to invite sight impaired people to test the devices.  The Trail Blazers allow the company to access the NBA's live gameplay tracking data that translates to vibrations on the device.  Tests will continue at the final two games of the season this week.
