     - a way to do user interface device research on EXTREMELY

-- mindstorms sensors too inaccurate for user interface controllers,
-  and the central units expensive
+- LEGO has already published a robotics invention series called
+  Mindstorms, which also contains Legot bricks with touch and light
+  sensors and a central unit to control them. Even the central unit
+  is quite expensive and existing sensor not yet proper or accurate
+  enough for controller use, we look them forward with interests.

+    - LEGOs have been popular toys for several decades (where)
     - several scientists and students have a background in LEGO bricks ;)
