“…Currently, however, no such hBCI systems are commercially available. If such system exists, its combination with a haptic device (Nam et al, 2014 , 2015 ) may provide better assistance to patients in movement and sensing. Whereas EMG/EOG combined with EEG can be used for control applications (e.g., wheelchair control), the most significant breakthrough in hBCI is the design of hybrid EEG–NIRS that can simultaneously decode electrical and hemodynamic brain activities.…”

In this article, non-invasive hybrid brain–computer interface (hBCI) technologies for improving classification accuracy and increasing the number of commands are reviewed. Hybridization combining more than two modalities is a new trend in brain imaging and prosthesis control. Electroencephalography (EEG), due to its easy use and fast temporal resolution, is most widely utilized in combination with other brain/non-brain signal acquisition modalities, for instance, functional near infrared spectroscopy (fNIRS), electromyography (EMG), electrooculography (EOG), and eye tracker. Three main purposes of hybridization are to increase the number of control commands, improve classification accuracy and reduce the signal detection time. Currently, such combinations of EEG + fNIRS and EEG + EOG are most commonly employed. Four principal components (i.e., hardware, paradigm, classifiers, and features) relevant to accuracy improvement are discussed. In the case of brain signals, motor imagination/movement tasks are combined with cognitive tasks to increase active brain–computer interface (BCI) accuracy. Active and reactive tasks sometimes are combined: motor imagination with steady-state evoked visual potentials (SSVEP) and motor imagination with P300. In the case of reactive tasks, SSVEP is most widely combined with P300 to increase the number of commands. Passive BCIs, however, are rare. After discussing the hardware and strategies involved in the development of hBCI, the second part examines the approaches used to increase the number of control commands and to enhance classification accuracy. The future prospects and the extension of hBCI in real-time applications for daily life scenarios are provided.

“…Operator performance can be improved with the implementation of haptic virtual fixtures and new vision modalities. However, haptic virtual fixtures for teleoperation are predominantly employed to increase awareness and understanding, not to directly assist in the teleoperated task [34]. For example, a novel augmented reality interface coupled with virtual fixtures reduced overall positioning error in a maintenance task; however, the fixtures primarily assisted as operator notifications [29].…”

This work presents a user-study evaluation of various visual and haptic feedback modes on a real telemanipulation platform. Of particular interest is the potential for haptic guidance virtual fixtures and 3D-mapping techniques to enhance efficiency and awareness in a simple teleoperated valve turn task. An RGB-Depth camera is used to gather real-time color and geometric data of the remote scene, and the operator is presented with either a monocular color video stream, a 3D-mapping voxel representation of the remote scene, or the ability to place a haptic guidance virtual fixture to help complete the telemanipulation task. The efficacy of the feedback modes is then explored experimentally through a user study, and the different modes are compared on the basis of objective and subjective metrics. Despite the simplistic task and numerous evaluation metrics, results show that the haptic virtual fixture resulted in significantly better collision avoidance compared to 3D visualization alone. Anticipated performance enhancements were also observed moving from 2D to 3D visualization. Remaining comparisons lead to exploratory inferences that inform future direction for focused and statistically significant studies.

“…The value of touch-enabling technologies in online retailing Touch interfaces have been found to have a number of successful applications in the fields of surgery, prototyping, and assistance for persons with visual impairment (Nam et al, 2014). While touch-enabling technologies have, so far, not yet found their way to the context of online commerce, previous studies on interactive technologies (among which touch technologies can be classified) have demonstrated a range of opportunities for creating consumer value in terms of entertainment along the various stages of the path-to-purchase (Pantano and Naccarato, 2010).…”

Purpose. A major factor hampering the continuing and explosive rise of e-commerce, particularly for experience goods, is the lack of tactile information that could help to reduce uncertainty in consumer purchase decision making online. The paper aims to identify the specific touch-related properties worthwhile to enable in online retailing and the type of customer value that can be provided, as well as the drivers and barriers for consumer acceptance towards touch-enabling technologies for online shopping. Methodology. By means of consumer focus groups we address the research questions regarding touch-related properties, their value to consumers and the drivers and barriers for consumer acceptance by taking into consideration two specific touch enabling technologies. Findings. The study reveals that touch-enabling technologies can provide utilitarian and hedonic value to consumers, mainly at the pre-purchase stages in the path-to-purchase. Valuable applications conceived by consumers primarily pertain to offering information on material and geometric product properties. A hurdle for consumer adoption seems to be the necessity of a dedicated output device, such as a glove. Research limitations/implications. Due to the early development stage of the new technologies under investigation, this study is exploratory in nature. The findings should be validated in the future, once these technologies actually get introduced for online marketing purposes. Practical implications. This study aims to raise awareness among online retailers of marketing opportunities comprised in touch-enabling technology. Originality. We provide a first outlook with regards to future consumer acceptance of touchenabling technologies in online shopping and how and when such technologies can provide consumer value.
