Description

A Usability Testing Method Based on Set Top Box

technical field

The invention belongs to the field of digital television, and in particular relates to a usability testing method based on a set-top box in digital television interactive services.

Background technique

With the continuous advancement and deepening of the "Digital Home Action Plan of Guangdong Province", in order to realize the goal of "using cable TV network as the main channel, digital TV as the center, interactive application as the guide, and 3C integration in the home", establish as soon as possible It is a digital home service system based on digital TV network, integrating various network interconnection technologies, equipment and content, and based on interconnection and user experience. For various interactive systems, it is necessary to build a set of usability testing standard system. By standardizing the usability test process, the test is more reasonable and scientific, so as to obtain scientific test data, improve various digital home devices and services, and make them more convenient for users to use. Standardize the format of test reports, present test results in a more comprehensive and organized manner, and make it easier for product development project teams and customer organizations to understand the extent to which products achieve their usability goals.

Traditional usability testing methods generally include thinking aloud, performance evaluation, field observation, questionnaires, interviews and other forms. However, these traditional methods face three major defects: First, to make the test results more in line with objective requirements, a large number of samples must be collected, and these samples must be evenly distributed among various regions, age groups, and different occupations, This is bound to increase the overhead of more manpower and other costs. Secondly, the traditional usability testing method takes a longer period of time to form a test report, which is not conducive to the rapid modification, update, and upgrade of products, so as to lose market share. Finally, because the traditional test method is to form the impression of the product through the memory of the parties after the event, it cannot well reflect the real feelings of the users at that time, and the tested users may also be affected by the site environment, expert opinions, and other opinions. Make your own judgment, so that the results obtained are not very objective and true.

During the research and practice of this method, the inventors of the present invention found a set-top box-based usability testing method in digital TV interactive services, which can effectively overcome the shortcomings of the above-mentioned traditional methods.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The embodiment of the present invention provides a set-top box-based usability testing method, which can effectively overcome the shortcomings of traditional usability testing. The embodiment of the present invention also provides a corresponding set-top box-based usability testing system in interactive services. Each will be described in detail below.

As shown in Figure 1, it is a dependency diagram of how to implement user-centered design activities before usability testing of interactive services.

101: Start with user-centered design requirements, then move on to 102

102: Understand the user's usage background in detail, then go to 103

103: In addition to understanding the user's usage background, to understand the user and organizational requirements, go to 104 after completing these

104: Propose a suitable design, then go to 105

105: According to some requirements determined above, test and evaluate the design scheme, if it passes, go to 106, otherwise go to 102

106: The system meets the needs of users and the organization

As shown in Figure 2 are some specifications of the usability test report. mainly include:

202: Title Page

203: Test Execution Summary

204: Introduction to Test Objects

205: Test basic information
