Virtual idols have aroused wide attention as a novel product of the idol industry in the digital era over the past few years. The population of China determines that virtual idols have a huge fan market. As a digital cultural product closely connected with fans, virtual idols are im-portant to gain insights into the correlation between fan satisfaction and virtual idol functions. In accordance with the KANO demand model, this study first classifies and explains the specific functions of virtual idols into four quadrants, including attractive, must-be, 1D (One-Dimensional), and indifferent. Subsequently, the satisfaction of fans of virtual idols with specific functions in each quadrant are analyzed using a questionnaire. This study suggests that virtual idols have one at-tractive quality, three 1D quality, two must-be quality, and five indifferent quality functional elements. This study qualitatively analyzes the functional elements of virtual idols through fan satisfaction based on the KANO model, which provides valuable help for future research in the field of virtual idols and producers in this field
Finite-time Incremental Stability Analysis for Nonlinear Switched Systems With Unstable Subsystems

In this paper, finite-time incremental stability (FTIS) and finite-time incremental boundedness (FTIB) are investigated for nonlinear switched systems (NSS) with unstable systems. Firstly, based on the reverse modedependent average dwell time (MDADT) method, we propose some sufficient conditions for FTIS of NSS. Secondly, the sufficient conditions for NSS to be FTIB with an incremental performance index are given by the multiple incremental Lyapunov functions. Finally, a distinctive advantage of reverse MDADT method is that each subsystems satisfies FTIB in the activation interval. A example has been provided to show the effectiveness of the theoretic results developed.
