我们建议通过允许对象传达动态使用来扩展对象的可供性，例如（1）运动（例如，喷雾罐在触摸时震动），（2）多步骤工艺（例如，喷雾可以仅在摇动后喷雾），和（3）随时间改变的行为（例如，空的喷雾罐不再允许喷雾）。然而，我们不是直接增强对象，而是通过增强用户来实现这个概念。我们称之为启示++。通过使用电肌肉刺激来刺激用户的手臂，我们的原型不仅允许对象使用户致动它们，而且还在仅仅接近对象时执行所需的运动，例如不触摸不“想”被触摸的对象。在我们的用户研究中，affordance++帮助参与者成功地操作了自然启示不佳的设备，例如多功能切片机工具或磁性指甲清扫器，并远离装满热液体的杯子。
We propose extending the affordance of objects by allowing them to communicate dynamic use, such as (1) motion (e.g., spray can shakes when touched), (2) multi-step processes (e.g., spray can sprays only after shaking), and (3) behaviors that change over time (e.g., empty spray can does not allow spraying anymore). Rather than enhancing objects directly, however, we implement this concept by enhancing the user. We call this affordance++. By stimulating the user's arms using electrical muscle stimulation, our prototype allows objects not only to make the user actuate them, but also perform required movements while merely approaching the object, such as not to touch objects that do not "want" to be touched. In our user study, affordance++ helped participants to successfully operate devices of poor natural affordance, such as a multi-functional slicer tool or a magnetic nail sweeper, and to stay away from cups filled with hot liquids.
