Usability evaluation support apparatus
First Claim
1. A usability evaluation support apparatus for supporting evaluation of usability of an instrument comprising a display unit for displaying information relative to a given task, the apparatus comprising:
- means for acquiring an operation log information which is related to an operation performed by a user and which includes at least one item of operation log data measured during performance of the task;
index evaluation means for generating at least one effectiveness index, efficiency index, and satisfaction index related to achieving a target of the task, wherein the index evaluation means evaluates and generates the effectiveness, efficiency, and satisfaction indexes by a statistical calculation using at least one data item included in at least one of a plurality of measurement items including the operation log information.

Abstract
There is disclosed an apparatus for supporting evaluation of usability of an instrument relative to performing a given task. During performing of the task, a control unit acquires information of an operation log related to an operation performed by a user, and evaluates an effectiveness index associated with achievement of the task, efficiency index associated with efficiency, and satisfaction index associated with subjective satisfaction of the user. The indexes are generated by a statistical calculation using a plurality of measured items, including the operation log information.
