Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for recording data obtained from an observer in an experiment to investigate the characteristics of Iruma's senses, such as a subjective evaluation experiment.

In recent years, advances in ergonomics have led to advancements in technology that reveals the characteristics of human senses, such as vision and hearing, and applies them to engineering. The human sensory characteristics that form the basis of this technology are determined through subjective evaluation experiments, in which a large amount of response data to the same experimental conditions is collected from the same observer, and this data is statistically processed.

2. Description of the Related Art The relationship between an observer and an experimenter data recording device in a conventional subjective evaluation experiment will be explained with reference to FIG. In FIG. 3, 1 is an observer, 2 is an experimenter, 3 is a data recording device, 31 is a data input section, and 32 is a data storage section. Experimenter 2 listened to the responses from observer 1 in the subjective evaluation experiment, and experimenter 2 inputted data from data input section 31 , and signals from the data input section were directly input to data storage section 32 .

Problems to be Solved by the Invention However, if the observer 1 corrects the response immediately after the experimenter 2 inputs all data into the data input section 31, or if the experimenter 2 inputs incorrect data into the data input section 31, If input, data different from the subjective evaluation of the observer 1 will be accumulated, and erroneous sensory characteristics will often be obtained that cannot be compensated for even by statistical processing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention temporarily displays the data input to the data recording device, and for each response, starts from 0.1 seconds after the data is displayed. If there is a data correction signal during the 6 seconds, the data recording device waits for data input, and if there is no data correction signal during the time interval, the displayed data is started to be recorded. It is something to do.

According to the present invention, correct data can be recorded by the above-described means after it is confirmed that there are no corrections to the observer's response or input errors by the experimenter.

EXAMPLE Hereinafter, an example of a data recording apparatus according to the present invention and the relationship between an observer and an experimenter will be described with reference to FIG.

In FIG. 1, 4 is an observer, 6 is an experimenter, e is a data recording device, 61 is a data input section, 62 is a data display section,
63 is a data correction official code generation section, and 64 is a data storage section.

The operation and usage of the embodiment of the present invention will be explained below based on FIG. In the description, it is assumed that the number of responses from the observer 4 is one. Experimenter 5 listens to the response from observer 4 in the subjective evaluation experiment, and inputs this response from data input section 61 . Data input from the data input section 61 is displayed on the data display section 62 for a certain period of time.

When the response from the observer 4 is corrected or the experimenter 5 finds a mistake in the data displayed on the data display section 62 at the above-mentioned time, the experimenter 5 operates the data correction signal generation section 63. , data input section 61 and data display section 6
A data correction signal is input to 2. When the data correction signal is input to the data input section 61 and the data display section 62 within the above-mentioned time, the data input section 61 and the data display section 62 return to the input waiting state, and the experimenter 6 can input correct data. . When the data correction signal is not input to the data input section 61 and the data display section 62 within the above-mentioned time, the data displayed on the data display section 62 is input to and stored in the data storage section.

The lower limit of the data display time is determined by the time it takes to clearly see all of the displayed data. 0 time to display data
．． If it is shorter than 1 second, the spatial resolution (visual acuity) of the human eye decreases (sensation + perception...Ndobook p268 Seishin Shobo), so the data display time must be 0.1 seconds or more.

The upper limit of the data display time is determined by the time required for the observer 4 to listen to the correction of the response and for the experimenter 5 to confirm the data displayed on the data display section. Although this data display time may be a long time, the time required for the experiment also becomes longer, which reduces the efficiency of the experiment and makes it difficult to obtain stable data due to the fatigue of the observer 4 and the like. Therefore, the upper limit of this data display time needs to be determined by the upper limit of the time required from when data is displayed until the experimenter operates the data correction signal generation section 63 in the subjective evaluation experiment.

FIG. 2 shows &1 in the embodiment of the invention based on FIG.
The histogram shows the result of recording the time from when the data is displayed on the data display section 62 until the observer 5 inputs the data correction signal. From Figure 2, data display section 6
It is clear that the data correction signal is not fully input after more than 6 seconds have passed since the data was displayed in No. 2. That is, the data display time may be within 6 seconds per piece of data.

With the above configuration, the data correction signal generation section 63 is also used as the data input section 61, and the observer 6 inputs data different from the response from the observer 4 to the data input section 61, so that the data correction signal can be input into the data. A similar effect can be obtained even with a configuration in which the generation occurs in the section 61.

Effects of the Invention According to the present invention, incorrect data can be quickly corrected in a king's appearance evaluation experiment that measures human sensory characteristics, so correct data can be recorded and ergonomic considerations can be made based on this. This makes it possible to develop new equipment.
