I. INTRODUCTION
With the rapid development of information technology
(IT), presentation tools are more and more widely used in
education, business, and other fields. A wireless
mouse-turning laser pointer has become a multi-functional
device combining traditional laser pointers and modern
wireless technology, providing users with a more
convenient and efficient demonstration experience. It can
not only realize the remote control of the PPT presentation
page turning function but also integrate the laser indication,
multimedia control, and other functions, which greatly
enriches the user's use scenario. However, in the current
market, full of a variety of different brands and models of
products, they have their own characteristics in
performance, design, ease of operation, and other aspects.
This complex market environment leads to consumers often
getting into a dilemma when choosing products. From a
design point of view, this highlights the importance of
scientific evaluation of products, as it can guide consumers
in their purchase. The purpose of this study is to
comprehensively evaluate the new wireless mouse
page-turning laser pointer through the analytic hierarchy
process (AHP) and provide valuable reference information
for designers to design a new wireless page-turning pen.
In the research process, the relevant study results of
comprehensive evaluation theory and the multi-attribute
decision method provide important theoretical basis and
method guidance for the construction and analysis of the

index system. For example, Guo's systematic description of
the comprehensive evaluation system in comprehensive
evaluation theory, method, and application enables us to
comprehensively evaluate products from multiple
dimensions; Gao's analysis of the system structure and the
relationship between elements in principles of systems
helps to better understand and build the hierarchical model
of wireless mouse page-turning laser pointer evaluation to
ensure reasonable and accurate logical relations among
elements [14, 18]. At the same time, in terms of weight
calculation and analysis, Deng and other scholars' in-depth
discussion on the weight calculation method of the analytic
hierarchy process in relevant studies is also referred to to
ensure the scientific accuracy and reliability of the
calculation results [15]. In addition, at the stage of data
collection and preliminary processing, Ma's management
statistics: data acquisition, statistical principles, SPSS tools,
and application research provide references for data
collection methods and statistical analysis principles to
ensure the validity of data and rationality of analysis [16].
Moreover, Fang's ideas and methods on building a
performance evaluation system in strategic performance
management also provide useful references for us to
determine evaluation indicators based on strategic
objectives, making evaluation indicators more targeted and
practical [17].
The novel wireless mouse page-turning laser pointer is
a modern demonstration aid that integrates wireless
communication technology and laser indicating functions.
Its main features include, but are not limited to, support for
remote page turning control, high-precision laser pointer,
multimedia file playback control, and black/white screen
switching functions. The product is designed with
portability and ergonomics in mind, making it easy to carry
and comfortable to use for a long time on a variety of
occasions. This paper will focus on these core features in
detail and build an A model based on the AHP method to
evaluate three representative schemes: Scheme A "Spirit
Leap Page Turning Pen", Scheme B "Changyi Page Turning
Pen" and Scheme C "Excellent Page Turning Master".
II. METHODS
2.1 Basic Principle of AHP
Analytic Hierarchy Process (AHP) is a combination of
qualitative and quantitative decision-making methods
proposed by Saaty T.L. [1], a famous American operations
research scientist, in the 1970s. It has been widely used in
various fields such as society, politics, economy, military,
and management. AHP is suitable for multi-index,
multi-level, and multi-scheme system comprehensive
evaluation and decision, especially for system problems
with both qualitative and quantitative factors. It can be
relatively simple to carry out a comprehensive evaluation
and the best plan decision [2].
The basic principle of AHP is to treat a complex
decision problem as a large system, and through in-depth
analysis of multiple influencing factors in the system, an
orderly hierarchical structure is built among the interrelated
factors [3]. Subsequently, experts are invited to make
objective judgments on the factors at each level and give
quantitative assessments of their relative importance. Based
on these judgments, mathematical models are built to
calculate the relative weights of all factors in each level and
rank them. Finally, according to the ranking results, a
decision scheme is made and effective measures are
selected to solve the problem.
For the construction method of the hierarchy, the
overall goal of the problem should be clearly defined and
placed at the top of the hierarchy. Then, according to the
nature of the problem and the purpose of the research, the
factors affecting the realization of the overall goal are
decomposed into several criterion layers; each criterion
layer can be further subdivided into several sub-criterion
layers, and so on, until it is decomposed into the specific
scheme layer that can be directly evaluated or decided.
The establishment of the judgment matrix is based on
the pairwise comparison between the factors of the same
level in the hierarchy. The 1-9 scale method is usually used
for comparison; that is, for two factors i and j, their relative
importance is expressed by the numbers 1-9 and their
reciprocal. Among them, 1 indicates that the two factors are
equally important, 3 indicates that factor i is slightly more
important than factor j, 5 indicates that factor i is
significantly more important than factor j, 7 indicates that
factor i is strongly important than factor j, 9 indicates that
factor i is extremely important than factor j, 2, 4, 6, and 8
indicate the middle value of the above adjacent judgments.
2.2 Establishment of Comprehensive Evaluation

Method
According to previous research results, the triangular
table survey method is used to ensure the consistency of the
constructed index weight judgment matrix. Meanwhile, the
"minimum variance" theory in classical mathematics is
adopted to determine the relative evaluation level weights
of different experts according to the difference level
between the actual weights evaluated by different experts
and the optimal weights (using the average value). To avoid
the subjective differences of individual evaluation experts
from having a greater impact on the evaluation results [4].
The specific evaluation process is shown in Figure 1.
Fig.1 Evaluation Flow Chart
2.3 The application of AHP to solve practical problems
can be generally carried out in the following four steps:
Step 1: Establish a hierarchical structure
When AHP is applied to analyze decision problem,
first of all, the problem should be organized and
hierarchical, and a hierarchical structure model should be
constructed. These levels can be divided into three types:
the highest level (the purpose level), the middle level (the
criterion level), the lowest level (the scheme level). The
number of layers in a hierarchical structure is related to the
complexity of the problem and the degree of detail that
needs to be analyzed, and the number of layers is generally
unlimited. The elements in each hierarchy generally control
no more than 9 elements [5].
Step 2: Construct all the judgment matrices in each
level
The criteria in the criterion layer do not necessarily
have the same weight in the objective measurement, and
they each have a certain proportion in the mind of the
decision maker. Define the judgment matrix A=(aij)nxn by
referring to the numbers 1-9 and their reciprocal as scales
(see Table 1)
Table 1 Definition of the Judgment Matrix Scale
Scale Meaning
1
Indicates that two factors are of equal
importance when compared
3
When compared with each other, the former is
slightly more important than the latter
5
It means that the former is significantly more
important than the latter when comparing two
factors
7
Means that the former is strongly more
important than the latter when compared with
the two factors
9
It means that the former is extremely more
important than the latter when comparing two
factors
2,4,6,8
Represents the median value of the above
neighboring judgments
Reciprocal
If the ratio of the importance of factor i to that
of factor j is aij, then the ratio of the
importance of factor j to that of factor i is
aji=1/a
Step 3: Single rank and consistency test
1) Calculate the consistency index (CI)
CI =
λ𝑚𝑎𝑥 − 𝑛
n − 1
(1)
Where λmax is the maximum eigenvalue of the judgment
matrix
2) Find the consistency indicator RI, such as Table 2.

Table 2 Average random consistency metrics
n 1 2 3 4 5 6 7 8 9 10 11 12 13 14
RI 0 0 0.52 0.89 1.12 1.24 1.36 1.41 1.46 1.49 1.52 1.54 1.56 1.58
Step 4: Hierarchy total sort and consistency check.
Finally, it is necessary to get the ranking weight of
each element, especially the scheme in the lowest layer to
the target, so as to select the scheme. The consistency test is
also needed for the overall ranking of the hierarchy, the
synthetic weight of the elements of each layer to the total
goal of the system is calculated, and the selected scheme is
sorted.
III. AHPANALYSIS MODEL CONSTRUCTIONS
3.1 Construction of Hierarchical Structure Model
The page-turning laser pointer is the process of
concretizing the evaluation content, using key indicators to
highly summarize the evaluation content, and decomposing
each indicator into specific indicators after comprehensive
weighing and scientific analysis. This model sets the target
layer as the comprehensive evaluation of the practicability
evaluation of the page-turning pen. The criterion layer
includes functional practicality, application scenario
adaptability, operation convenience, technical stability,
battery life, and charging. The scheme layer is A, B, and C
[6], as shown in Figure 2.
Fig. 2 Structure Model Diagram
3.2 Determine the Evaluation Index System
Establish the standard to measure the pairwise
comparison of different evaluation indicators, and construct
the matrix of the pairwise comparison results of different
indicators. All indicators in each scheme are scored,
respectively, and a weighted average is used to calculate the
relative weight of each indicator under each scheme by
using the results of the previous step. This model
determines the evaluation index of the new wireless mouse
page-turning laser pointer from the aspects of performance,
function, design, price, etc. and refers to the relevant
comprehensive evaluation theory and the research results of
multi-attribute decision methods [7, 8, 9].
IV. DATA PROCESSING
4.1 Establishment and Assignment of Judgment Matrix
Based on the evaluation of the practicability of the
page-turning pen, functional practicability, scene

method of the judgment matrix construction in the analytic
hierarchy process and related research cases are used for
reference [10,11].

V. ANALYSIS RESULTS AND DISCUSSION
5.1 Analysis of Calculation Results
The relevant factors in the first intermediate layer
include scenario adaptability, functional practicality, battery
life and charging, technical stability and operation
convenience, which are quantified to reflect the different
importance of these factors relative to the decision goal, that
is, the ranking weight (Table 9). Among them, the factor
with the largest proportion of weight is the proportion of use
scenario adaptability, accounting for 0.3158. The weight of
the three middle layer factors, battery life and charging,
technical stability and operation convenience, is the same,
all of which are 0.1579. It shows that the use of scene has
the greatest impact on the first intermediate layer factor, and
the direction of the performance of the whole page turning
pen is also greater.
The second intermediate layer factor has 15 factors,
with the most weight for conference room use, followed by
signal connection stability and battery life. These three
factors have a larger weight, accounting for almost 0.33 of
the weight of the middle layer, and each of the remaining
factors accounts for no more than 0.1, among which, the
lowest factor is the black screen/white screen function.
