Abstract: Methods and a wearable device are provided. A response of a query is generated. The query is divided into several segments. An entropy of each segment is calculated. The segments are displayed when their entropy is greater than a threshold. In addition, a display format of the response is determined based on an index which is calculated according to context information and display information of the corresponding display format.
