Every day, we make thousands of finger movements on the touchscreen of our smartphones. The same movements might be directed at various distal goals. We can type "What is the weather in Rome?" in Google to acquire information from a weather site, or we may type it on WhatsApp to decide whether to visit Rome with a friend. In this study, we show that by watching an agent's typing hands, an observer can infer whether the agent is typing on the smartphone to obtain information or to share it with others. The probability of answering correctly varies with age and typing style. According to embodied cognition, we propose that the recognition process relies on detecting subtle differences in the agent's movement, a skill that grows with sensorimotor competence. We expect that this preliminary work will serve as a starting point for further research on sensorimotor representations of digital actions.
每天，我们在智能手机的触摸屏上会进行数千次手指动作。同样的动作可能指向各种不同的最终目标。我们可以在谷歌中输入“罗马的天气如何？”以从天气网站获取信息，或者我们可能在WhatsApp上输入它，以便决定是否与朋友一起去罗马游玩。在本研究中，我们表明，通过观察一个人的打字手部动作，观察者可以推断出这个人是在智能手机上打字以获取信息还是与他人分享信息。正确回答的概率会因年龄和打字风格而有所不同。根据具身认知理论，我们提出，识别过程依赖于检测动作执行者动作中的细微差异，而这种技能会随着感觉运动能力的发展而提高。我们期望这项初步工作将成为进一步研究数字动作的感觉运动表征的起点。
