本研究采用单一受试的多重处实验设计，研究个案为一名国小中级的高功能自闭症学童，自变项为游戏式CAI，依变项为动作能和注意，透过游戏式CAI教学方案的介入后，将所搜集的资进视觉分析与C 统计，所得结果统整后，归纳出以下三项结：一、经由游戏式CAI教学方案的教学介入后，确实能提升个案的整体动作能，并在教学介入撤除后，仍具有维持效果。

On the basis of its importance both in theoretical research and practical application, gait recognition needs to be further studied. With the help of current research findings, this thesis has made the following innovative contributions: 1. Based on the perceptual shape descriptors and the eigenspace transformation, a new automatic gait recognition algorithm is proposed. The principal component analysis and the multiple discriminant analysis are used to reduce data dimensionality and to optimize the separability of different classes.

The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.
