“…These effects have not been clarified yet and researchers who are using BC transducers have avoided the existence of hair between the skin and the BC transducer. 31,32) However, as some recent BC transducers are placed just in front of the ear, [33][34][35][36] the effects of hair between the skin and BC transducers cannot be ignored. Figure 1 shows the overview of these factors.…”

Noninvasive bone-conducted hearing aids require the consistent fitting of transducers for consistent hearing. In this paper, a method of estimating the contact force and amount of hair between a person’s skin and a bone-conducted sound transducer using electrical impedance is proposed. Experiments are conducted with a human surface model consisting of hair, skin, and bone. The estimator is implemented with a three-layered neural network. Ten measurements for 70 conditions are conducted by changing the contact force from 0 to 5 N and the amount of hair from 0 to 169.6 mm3. With the trained estimator, it is possible to estimate contact force and the intermediate material thickness with mean errors of 0.025 N and 0.424 mm3. This result supports the feasibility of the proposed method and contributes to the reproducible placement of the bone-conducted sound transducer.

“…Norman [7] examines the current challenges in the deployment of haptic-based distributed systems and progress to overcome the network impairment challenges. Lindeman [8] designs a wireless tactor prototype which allows haptic feedback in virtual reality. However, their prototype is based on a simple wireless broadcasting and doesn't consider wireless networked system.…”

This paper presents an experimental investigation into a new peer-to-peer wireless network architecture for real time telehaptic operation in distributed virtual environments (DVEs). The new peer-to-peer architecture is able to support haptic interactions over different wireless network architecture. Experiments have been conducted to show the performance of different wireless architecture, i. e. wireless-B/G/N. Experiments have also been conducted to investigate the performance of this architecture. Findings of the study are presented in this paper and it shows the challenges in conducting haptic collaboration over wireless IP networks. This is especially true when the wireless hops increase. The wireless channel condition varies over time due to such factors as channel characteristics, the PHY scheme selected, time-varying interference, and channel width for the particular wireless architecture.

this paper presents an investigation into a new peerto-peer wireless network architecture for real time tele-haptic operation in distributed virtual environments (DVEs). A novel force collaboration and position synchronization algorithm is developed in order to support wireless networked haptic interactions. The new peer-to-peer architecture is able to support haptic interactions over wireless IP networkes. Experiments have been conducted to show the performance of this with different wireless hopping. Experiments have also been conducted to investigate the threshold levels of QoS required (i.e. number of wireless hopping) for wireless networked haptic collaboration. Findings of the study are presented in this paper and it shows the challenges in conducting haptic collaboration over wireless IP networks. The wireless channel condition varies over time due to such factors as channel characteristics, the PHY scheme selected, time-varying interference, and the priority of services (QoS demands) from MAC/PHY layers.
