Objective

To determine how changing and informing a user of the false alarm (FA) rate of an automated target recognition (ATR) system affects the user’s trust in and reliance on the system and their performance during an underwater mine detection task.

Background

ATR systems are designed to operate using a high sensitivity and a liberal decision criterion to reduce the risk of the ATR system missing a target. A high number of FAs in general may lead to a decrease in operator trust and reliance.

Methods

Participants viewed sonar images and were asked to identify mines in the images. They performed the task without ATR and with ATR at a lower and higher FA rate. The participants were split into two groups—one informed and one uninformed of the changed FA rate. Trust and/or confidence in detecting mines was measured after each block.

Results

When not informed of the FA rate, the FA rate had a significant effect on the participants’ response bias. Participants had greater trust in the system and a more consistent response bias when informed of the FA rate. Sensitivity and confidence were not influenced by disclosure of the FA rate but were significantly worse for the high FA rate condition compared with performance without the ATR.

Conclusion and application

Informing a user of the FA rate of automation may positively influence the level of trust in and reliance on the aid.

告知参与者自动目标识别系统的响应偏差对信任和依赖行为的影响

客观的

确定改变和通知用户自动目标识别 (ATR) 系统的误报 (FA) 率如何影响用户对系统的信任和依赖，以及他们在水下探雷任务中的表现。

背景

ATR 系统旨在使用高灵敏度和宽松的决策标准进行操作，以降低 ATR 系统错过目标的风险。一般来说，大量 FA 可能会导致运营商信任度和依赖度下降。

方法

参与者查看声纳图像并被要求识别图像中的地雷。他们在没有 ATR 和 ATR 的情况下以较低和较高的 FA 率执行任务。参与者被分成两组——一组知道 FA 率的变化，另一组不知道。在每个区块之后测量对检测地雷的信任和/或信心。

结果

当未被告知 FA 率时，FA 率对参与者的反应偏差有显着影响。当被告知 FA 率时，参与者对系统有更大的信任和更一致的反应偏差。敏感性和信心不受 FA 率披露的影响，但与没有 ATR 的表现相比，高 FA 率条件下的敏感性和信心明显更差。

结论与应用

将 FA 自动化率告知用户可能会对援助的信任度和依赖度产生积极影响。
