Ninja cursors use multiple synchronized cursors to reduce target acquisition time on large displays. An experiment with 4 cursor conditions (1, 2, 8, and 18 cursors) and 3 target densities found that 2 and 8 cursors performed best, reducing time by distributing targets across cursors. However, more cursors led to annoyance from frequent blocking and waiting. Advanced features like drag and drop and lasso selection were also explored.
