As Internet of Things (IoT) technologies are increasingly being deployed, situations frequently arise where multiple stakeholders must reconcile preferences to control a shared resource. We perform a 5-month long experiment dubbed "smartSDH" (carried out in 27 employees' office space) where users report their preferences for the brightness of overhead lighting. smartSDH implements a modified Vickrey-Clarke-Groves (VCG) mechanism; assuming users are rational, it incentivizes truthful reporting, implements the socially desirable outcome, and compensates participants to ensure higher payoffs under smartSDH when compared with the default outside option. smartSDH assesses the feasibility of the VCG mechanism in the context of smart building control and evaluated smartSDH's effect using metrics such as light level satisfaction, incentive satisfaction, and energy consumption. Despite the mechanism's theoretical properties, we found participants were significantly less satisfied with light brightness and incentives determined by the VCG mechanism over time. These data suggest the need for more realistic behavioral models to design IoT technologies and highlights difficulties in estimating preferences from observable external factors such as atmospheric conditions.

smartSDH：建筑控制的机制设计方法

随着物联网 (IoT) 技术的部署越来越多，经常出现多个利益相关者必须协调偏好以控制共享资源的情况。我们进行了一项为期 5 个月的名为“smartSDH”的实验（在 27 名员工的办公空间中进行），用户报告了他们对顶灯亮度的偏好。smartSDH 实现了修改后的 Vickrey-Clarke-Groves (VCG) 机制；假设用户是理性的，它会激励真实的报告，实现社会期望的结果，并补偿参与者以确保与默认的外部选项相比，smartSDH 下的回报更高。smartSDH 在智能楼宇控制的背景下评估 VCG 机制的可行性，并使用光照水平满意度等指标评估 smartSDH 的效果，激励满意度和能源消耗。尽管该机制具有理论特性，但我们发现参与者对 VCG 机制随着时间的推移确定的光亮度和激励的满意度明显较低。这些数据表明需要更现实的行为模型来设计物联网技术，并突出了从可观察的外部因素（如大气条件）估计偏好的困难。
