    摘要： An error-correction apparatus and method and a three-dimensional (3D) pointing device using the error-correction apparatus are provided. The error-correction apparatus includes a data-collection module which collects current data and calculates an actual variation in the current data; an estimation module which calculates an estimated data variation for the current data based on a number of data variations for respective corresponding previous data; a threshold-calculation module which calculates a variable threshold based on the data variations for the respective previous data; and a determination module which compares the difference between the actual data variation and the estimated data variation with the variable threshold and determines whether the current data is erroneous based on the result of the comparison.
