Jeffery DeJong



Partnered with Boccia England, a national governing body, to create a modern scorekeeping solution.

I designed an iPad app that connected to a big screen. The scoreboard was used at local, national and international competitions as well as the National Paralympic Day in London.

National Paralympic Day


Used by officials with a range of technology experience and physical abilities.

Volunteers may not have ever used an iPad before.
Skeuomorphism was used to make the experience more familiar to a traditional physical scoreboard.
iPad interface – controls for each competitor to start timer or increase score, an edit button, and end indicator with next end button.
During user research, I observed indivdiuals having difficulty swiping the screen to scroll.
Added tapable scroll buttons.
History with search functionality


Match results were shown on a large screen for players and spectators.

Information on the screen needed to be read from at least 10 meters away.
Included additional graphical cues to support the contrast and typography.

  • the position of the highlighted circle within a set of ends indicates the end being played, even if the number cannot be read
  • a time-remaining ring provided a bold visual indicator of timing, which can be seen from a greater distance than the numerical display
  • different audio alerts notified officials and players when time-remaining reaches key points.
