Thesis (Ph.D.)--Stanford University, 2023.

We use haptic information to understand and interact with our surrounding environment in daily life. Haptic devices can similarly augment our understanding of both our world and digital environments by providing touch-based information and feedback. Traditionally, haptic devices have provided kinesthetic feedback, imparting large forces and torques to a user, resulting in a bulky, heavy, and immobile setup. However, cutaneous or tactile feedback can be used to provide skin deformation or vibration with lower forces in mobile, lightweight setups.With the advent of soft robotics allowing for lightweight actuation and small vibration actua- tors embedded in ubiquitous smartphones, we can design and study how mobile tactile feedback is perceived by users. Mobile haptic devices have the potential to enhance our experience with tech- nology in daily life by providing information in a variety of applications including virtual reality, transportation, and gaming. Therefore, this thesis examines the design and perception of mobile tactile displays to inform the design of haptic devices that can be used outside of the lab in daily life.First, we present the design and evaluation of a 3-DoF wearable haptic device that can provide normal, torsion, shear, and vibration enes on the forearm. In this device, we integrate soft, pneumatic actuators to provide linear movements and introduce a model that can be used to optimize actuator parameters. User studies validated that participants can perceive linear shear cucs created by the device and that different actuation patterns impact cue identification accuracy.Second, we introduce and test a smartphone platform that can be used to quantify vibration thresholds. We create an app for an iPhone that delivers and records responses to vibrations and conduct a user study measuring how people perceive these vibrations in the presence of physical and cognitive activity. We find that the ability to perceive vibrations diminishes in the presence of both physical and cognitive activity and that cognitive activity increases response times to vibrations.Last, we develop a smartphone app that measures response times to multi-modal stimuli. The app tests 26 combinations of three levels of audio, haptic and visual stimuli and measures response times via a button press. We conduct a user study to measure response times in each condition and find that participants respond faster with higher levels and mure types of stimuli while also having a preference toward stimuli that have slower response times.
