Abstract: A reflective active variable lens includes an upper electrode, a lower electrode disposed in parallel to the upper electrode, a deformation part disposed between the upper electrode and the lower electrode, a reflective part disposed on the upper electrode, and a support part disposed to surround the deformation part. Here, the deformation part and the support part are connected to each other to provide a single structure, the deformation part is expanded from an initial shape when an electric field is formed between the upper electrode and the lower electrode, and the expanded deformation part is contracted when the electric field is removed and restored to the initial shape.

Abstract: Disclosed is a dating recommendation platform including a first server that receives first data and second data from an external electronic device, generates time-series data including characteristic data generated for each period in response to the first data and the second data by analyzing the second data, and generates personal preference data by performing classifications from the first to the seventh based on the time-series data, and a second server that receives the personal preference data from the first server, anonymizes the first data included in the personal preference data, generates image data based on the anonymized personal preference data, and outputs the generated image data to the external electronic device. The characteristic data includes information about at least one of an action, an emotion, a place, a speech, a movement, and a circumstance of a user.
