THE INFLUENCE OF PRODUCT PRESENTATION MODE AND ACADEMIC MAJOR ON THE MOTIVATION OF HAPTIC

Purpose of the study: This study was aimed to investigate the effect of product presentation mode and education background of the subject on the willingness of touch, preferences and visual imagery. Methodology: A total of 60 students were recruited to participate. The independent variables included product presentation mode (physical products, backgrounds removed image, scenario photo) and academic major of the subject (design major or management major). Three different kind dependent variables were measured in the study. On physical product condition, one sample was placed in front of subjects at a time. Both backgrounds removed image and scenario photo conditions, the subjects view experimental photos through a 22-inch LCD screen. They watched the sample item for 10 seconds and then were asked to assess the subjective questionnaire. Main Findings: The study results showed that when watching a physical product, the motivation of touch was greatest. The scenario photo generated more positive feelings and resulted in higher preference rating. The willingness of touch, preference and sensory ratings of management major students were higher than design major students. Applications of this study: The findings of this study can serve as a reference for enterprises to properly present products on web pages in order to increase consumers’ motivation to touch and preference. Novelty/Originality of this study: This study reinforces construction of a model of motivation to touch, and find that product presentation mode significant affect motivation to touch, preference and novelty feeling

Inertia of partial transpose of positive semidefinite matrices

We show that the partial transpose of $9\times 9$ positive semidefinite matrices do not have inertia (4,1,4) and (3,2,4). It solves an open problem in "LINEAR AND MULTILINEAR ALGEBRA, Changchun Feng et al, 2022". We apply our results to construct some inertia, as well as present the list of all possible inertia of partial transpose of $12\times 12$ positive semidefinite matrices.Comment: 20 pages, comments are welcom

Study the Heavy Molecular States in Quark Model with Meson Exchange Interaction

Some charmonium-like resonances such as X(3872) can be interpreted as possible $D^{(*)}D^{(*)}$ molecular states. Within the quark model, we study the structure of such molecular states and the similar $B^{(*)}B^{(*)}$ molecular states by taking into account of the light meson exchange ($\pi$, $\eta$, $\rho$, $\omega$ and $\sigma$) between two light quarks from different mesons
