“…to improve the simulation realism by adding a "virtual jet" of blood in case of a possible needle insertion after pulse palpation) [5,6]. Examples of implementing a pulse simulator include: using an hydraulic interface (with an hydraulic pump to inflate a tube) to provide a physical replica of a pulsating vessel [5,6]; using the acoustic Radiation Pressure (ARP) phenomena generated by focusing multiple ultrasonic transducers to create perceivable vibrations trough an haptic interface [7,8]; integrating different tactile devices, based on a piezoelectric pads, a micro speakers, or a pin array, into a commercial force feedback device (Falcon by Novint Technologies, Inc.) [4]. In this work we propose a tactile augmented reality system for open-surgery simulation.…”

Palpation is an essential step of several open surgical procedures for locating arteries by arterial pulse detection. In this context, surgical simulation would ideally provide realistic haptic sensations to the operator. This paper presents a proof of concept implementation of tactile augmented reality for open-surgery training. The system is based on the integration of a wearable tactile device into an augmented physical simulator which allows the real time tracking of artery reproductions and the user finger and provides pulse feedback during palpation. Preliminary qualitative test showed a general consensus among surgeons regarding the realism of the arterial pulse feedback and the usefulness of tactile augmented reality in open-surgery simulators

“…There was no main effect of sex (p = 0.9). MANOVA results revealed a main effect of stimulus (F (3,12) = 78.879, p < 0.001, ηp 2 = 0.952). Univariate testing revealed a significant stimulus by absolute error interaction (F (1,14) = 17.839, p < 0.001, ηp 2 = 0.560), demonstrating larger error during the auditory trials.…”

Audiohaptic Feedback Enhances Motor Performance in a Low-Fidelity Simulated Drilling Task

When used in educational settings, simulations utilizing virtual reality (VR) technologies can reduce training costs while providing a safe and effective learning environment. Tasks can be easily modified to maximize learning objectives of different levels of trainees (e.g., novice, intermediate, expert), and can be repeated for the development of psychomotor skills. VR offers a multisensory experience, providing visual, auditory, and haptic sensations with varying levels of fidelity. While simulating visual and auditory stimuli is relatively easy and cost-effective, similar representations of haptic sensation still require further development. Evidence suggests that mixing high- and low-fidelity realistic sensations (e.g., audition and haptic) can improve the overall perception of realism, however, whether this also leads to improved performance has not been examined. The current study examined whether audiohaptic stimuli presented in a virtual drilling task can lead to improved motor performance and subjective realism, compared to auditory stimuli alone. Right-handed participants (n = 16) completed 100 drilling trials of each stimulus type. Performance measures indicated that participants overshot the target during auditory trials, and undershot the target during audiohaptic trials. Undershooting is thought to be indicative of improved performance, optimizing both time and energy requirements.

“…As a consequence, many haptic deployments focus primarily on the pulse rate, representing the pulse as a series of square or triangle waves for implementation simplicity. Examples include Coles and Ullrich [3][4][5].…”

Cardiovascular disease is the leading cause of death worldwide. According to the World Health Organization, cardiovascular disease was responsible for 17.5 million deaths in 2012, or 30% of all deaths. Recent research suggests that, in addition to pulse rate, the pulse waveform itself contains useful diagnostic information. To explore tactile representation of these waveforms, this demonstration deploys a haptic representation of the aortic pressure profile synchronized to a synthetic electrocardiogram using a consumer grade haptic interface.
