“…Although MoSART offers better performance in terms of latency and jitter, its overall weight and footprint are significantly higher with respect to the device investigated in this study. Specifically, the weight of 1 kg is likely to compromise the usability of the HMP in various applications such in military and medical fields [ 30 , 35 ].…”

The growing interest in augmented reality applications has led to an in-depth look at the performance of head-mounted displays and their testing in numerous domains. Other devices for augmenting the real world with virtual information are presented less frequently and usually focus on the description of the device rather than on its performance analysis. This is the case of projected augmented reality, which, compared to head-worn AR displays, offers the advantages of being simultaneously accessible by multiple users whilst preserving user awareness of the environment and feeling of immersion. This work provides a general evaluation of a custom-made head-mounted projector for the aid of precision manual tasks through an experimental protocol designed for investigating spatial and temporal registration and their combination. The results of the tests show that the accuracy (0.6±0.1 mm of spatial registration error) and motion-to-photon latency (113±12 ms) make the proposed solution suitable for guiding precision tasks.

This is the case of projected augmented reality, which, compared to head-worn AR displays, offers the advantages of being simultaneously accessible by multiple users whilst preserving user awareness of the environment and feeling of immersion. This work provides a general evaluation of a head-mounted projector for precision manual tasks and a detailed description of the experimental protocol applied for investigating spatial and temporal registration and their combination in a user test. The results show that the accuracy and latency of the device make it suitable for guiding precision tasks.

“…Real-world BCI systems (as well as other personal telemonitoring systems) constantly face the daunting challenge of providing reliable long-term monitoring results in the ever-changing real-world situations using only battery-powered devices. As Cummings pointed out in her paper (Cummings, 2010 ), the necessary technology for hardware miniaturization and algorithmic improvement may not become available in the near future. Meanwhile, it is simply impossible to perform the computation and communication demanding tasks on these wearable systems: computation offloading provides the only viable solution, and the adoption of Fog Computing paradigm was the practical engineering approach we chose to tackle this challenge.…”

EEG-based Brain-computer interfaces (BCI) are facing basic challenges in real-world applications. The technical difficulties in developing truly wearable BCI systems that are capable of making reliable real-time prediction of users' cognitive states in dynamic real-life situations may seem almost insurmountable at times. Fortunately, recent advances in miniature sensors, wireless communication and distributed computing technologies offered promising ways to bridge these chasms. In this paper, we report an attempt to develop a pervasive on-line EEG-BCI system using state-of-art technologies including multi-tier Fog and Cloud Computing, semantic Linked Data search, and adaptive prediction/classification models. To verify our approach, we implement a pilot system by employing wireless dry-electrode EEG headsets and MEMS motion sensors as the front-end devices, Android mobile phones as the personal user interfaces, compact personal computers as the near-end Fog Servers and the computer clusters hosted by the Taiwan National Center for High-performance Computing (NCHC) as the far-end Cloud Servers. We succeeded in conducting synchronous multi-modal global data streaming in March and then running a multi-player on-line EEG-BCI game in September, 2013. We are currently working with the ARL Translational Neuroscience Branch to use our system in real-life personal stress monitoring and the UCSD Movement Disorder Center to conduct in-home Parkinson's disease patient monitoring experiments. We shall proceed to develop the necessary BCI ontology and introduce automatic semantic annotation and progressive model refinement capability to our system.
