Pushing Yourself Harder: The Effects of Mobile Touch Modes on Users’ Self-Regulation
研究发现，在手机交互中用力按压屏幕（而非轻点）能激活用户的趋近动机，促使其选择健康饮料、设定更高运动目标并减少卫生疏忽，对数字健康产品设计者和政策制定者有参考价值。
Mobile health interventions are widely used to facilitate individuals’ management of their health behavior. A notable issue is that health interventions with obvious persuasive intent may cause negligence and reactance. In this study, we propose a subtle but powerful way to bolster self-regulation in maintaining healthy behavior by leveraging embodied interaction design. Our study shows that bodily actions in interacting with digital devices can trigger thoughts about prior associated experiences and, thus, be strategically designed to affect individuals’ judgments, decisions, and behavior. Specifically, in three experiments, we find that firmly pressing a touchscreen during mobile interaction (as compared with gently tapping a touchscreen) can activate users’ approach motivation and, thus, induce their preference for a healthy over a tasty beverage, lead to more challenging exercise goals and more exercise, and reduce personal hygiene lapses after receiving hygiene education. Hence, designers of digital health products may consider designing interaction with pressing gestures to facilitate users’ self-regulation and attainment of health-related goals. Policymakers can also encourage the adoption of relevant app designs to improve citizens’ health wellbeing.
