“…Tactile feedback with soft and/or textile pneumatic actuators has been demonstrated in (e.g.) the following works: tactile cues with fingertip-mounted actuators [5,16,32], haptic armbands [11,23,28], soft buttons with pneumotactile feedback [8,35], a haptic jacket [3], physical touch to augment phone calls [25], headmounted tactile actuators for VR-interactions [10], and others. This overview is kept short for brevity, a variety [1] of further notable research in this area exists [9,14,21,31,35,[38][39][40] and updated overviews are provided in [2,29].…”

“…Pressure Modulations: Data-Driven Pneumotactile Feedback. Time-based pressure modulations are generated from time-series data sets (such as a real-time FFT-analysis 10 data from an audio source or file) and do not rely on pre-defined pressureprofiles. They also do not require active finger scanning motion by the user, as the dynamic tactile output continuously changes independently of the finger position.…”

This paper gives an overview of our work-in-progress prototype of a textile-pneumatic force-feedback system that augments the user-interaction on touch-sensor strips with interactive tactile cues. Air-pressure inside a shape-changing textile actuator is dynamically modulated, to create a perceivable pinch-like impression at the user's fingertip. This dynamic pneumotactile pinch can be leveraged as a tangible output modality for interaction design. The soft actuators are driven by a pneumatic control system that adjusts the pneumatic pressure in response to the finger position. We have explored different textile air-chamber layouts to achieve tactile feedback and provide a preliminary discussion of their tactile capabilities and design patterns. We further give a brief overview of three different pneumatic control system architectures and their underlying tactile pressure profiles used to operate the actuators to create different types of tactile sensations. A preliminary discussion of the capabilities, challenges, and limitations of our system is also provided.

“…They stressed that presenting haptic force feedback to the user performing such tasks increased the effectiveness, although this is a debatable subject [158]. Another example of the use of the direct force feedback method is PneumoVolley [159]. The authors, Schon et al, presented a wearable cap prototype that is capable of providing pressure feedback to simulate the interaction between a virtual ball and the user's head through pneumatic actuation.…”

Interactions in Augmented and Mixed Reality: An Overview

“Interaction” represents a critical term in the augmented and mixed reality ecosystem. Today, in mixed reality environments and applications, interaction occupies the joint space between any combination of humans, physical environment, and computers. Although interaction methods and techniques have been extensively examined in recent decades in the field of human-computer interaction, they still should be reidentified in the context of immersive realities. The latest technological advancements in sensors, processing power and technologies, including the internet of things and the 5G GSM network, led to innovative and advanced input methods and enforced computer environmental perception. For example, ubiquitous sensors under a high-speed GSM network may enhance mobile users’ interactions with physical or virtual objects. As technological advancements emerge, researchers create umbrella terms to define their work, such as multimodal, tangible, and collaborative interactions. However, although they serve their purpose, various naming trends overlap in terminology, diverge in definitions, and lack modality and conceptual framework classifications. This paper presents a modality-based interaction-oriented diagram for researchers to position their work and defines taxonomy ground rules to expand and adjust this diagram when novel interaction approaches emerge.

“…The core enabling technology for VR is software and hardware components for synthesizing appropriate physical signals for our five senses, which mimics the signals generated during real interactions. Due to recent advances in computer graphics and immersive visual display technology, the fidelity of visual feedback is reaching the level of the Turing test where a normal human can hardly distinguish between real and synthesized scenes [2]. The fidelity of haptic feedback, however, is still quite inferior to that of visual feedback in most VR systems [3], which is one of the areas that needs a technological breakthrough in VR [4].…”

Soft Pneumatic Fingertip Actuator Incorporating a Dual Air Chamber to Generate Multi-Mode Simultaneous Tactile Feedback

et al. 2021

A complete set of diverse haptic feedbacks is essential for a highly realistic and immersive virtual environment. In this sense, a multi-mode haptic interface that simultaneously generates multiple kinds of haptic signals is highly desirable. In this paper, we propose a new silicone-made pneumatically controlled fingertip actuator to render pressure and vibrotactile feedback concurrently to offer a realistic and effective haptic sensation. A new silicone-based stacked dual-layer air chamber was designed. The volume of the chambers is controlled by pneumatic valves with compressed air tanks. The top/upper air chamber renders vibration feedback, whereas the bottom/lower air chamber renders pressure feedback. The proposed silicone-made fingertip actuator is designed so that it can be easily worn at the fingertips. To demonstrate the potential of the system, a virtual environment for rendering three different types of haptic textures was implemented. Extensive performance evaluation and user studies were carried out to demonstrate the proposed actuator’s effectiveness compared to an actuator with single vibrotactile feedback.
