Blue Eyes Technology

The Blue Eyes technology aims at creating computational machines that have perceptual and sensory ability like those of human beings. It uses non-obtrusive sensing method, employing most modern video cameras and microphones to identify the user’s actions through the use of imparted sensory abilities. The machine can understand what a user wants, where he is looking at, and even realize his physical or emotional states. The Blue Eyes Technology developed is intended to be a complex solution for monitoring and recording the operator’s conscious brain involvement as well as his/her physiological condition. This shows yet another development in the field of Brain Computer Interface. The basic idea behind this technology is to give the computer the human power. We all have some perceptual abilities. That is we can understand each other’s feelings. For example we can understand one’s emotional state by analysing his facial expression. If we add these perceptual abilities of human to computers would enable computers to work together with human beings as intimate partners. The “BLUE EYES” technology aims at creating computational machines that have perceptual and sensory ability like those of human beings. This paper discusses the concept of blue eyes technology.

Ischemic stroke with agraphestesia signal focus

Introduction: The ischemic stroke is one of the main causes of death and disability in Brazil. Among the main risk factors are age, atrial fibrillation (AF), diabetes, dyslipidemia and physical inactivity. The main etiology of stroke is cardioembolic, resulting in obstruction of the cerebral arteries by a thrombus of cardiac origin. The artery most affected in ischemic strokes is the middle cerebral artery. The stroke has main characteristics, with emphasis on the sudden onset of symptoms, involvement of a focal area, ischemia caused by obstruction of a vessel and neurological deficits depending on the affected area. Graphesthesia is defined as a cutaneous sensory ability to recognize letters or numbers traced on the skin. The loss of this sensory ability is known as agraphesthesia. Case Report: M.A.F.O. female, 78a, arrived at the UPA complaining of mental confusion. Patient denies previous stroke. Personal history of systemic arterial hypertension. Upon physical examination, the patient was conscious, self and disoriented and inattentive. He was able to repeat and evoke words, without measurable motor déficits. Left upper limb with agraphestesia. Computed tomography was requested, which showed an extensive hypodense area in the right parietoccipital region, which leads to the erasure of the furrows between the adjacent gyres, which may correspond to a recent ischemic event. Magnetic resonance imaging, diffusion-restricted area with correspondence on the ADC map, located in the right temporoparietal region inferring an acute ischemic event. An electrocardiogram was also requested, which showed an irregular rhythm, characteristic of atrial fibrillation, resulting in a diagnostic hypothesis of cardioembolic ischemic stroke. Discussion: The involvement of post-central ischemic gyrus lesions may correspond to paresthesia, anesthesia, hypoesthesia; the involvement of secondary and terciary areas of sensitivity in the upper parietal lobe, especially in the active movements of the hand and in the modalities of integrated sensitivity, their lesions may be clinically affected by: apraxias, dysgraphias, hemineglect, agraphestesia, stereoagnosia and spacial disorientation.

Adaptive evolution of olfactory degeneration in recently flightless insects

Fast-moving animals need fast-acting sensory systems. Flying insects have thus evolved exceptionally quick visual (1) and olfactory processing ability (2). For example, flighted insects can track the temporal structure of turbulent odor plumes at rates above 100 Hz (3). The evolutionary lability of such sensory systems, however, remains unknown. We test for rapid evolutionary shifts in olfactory processing speed associated with flight loss, through neurobiological comparisons of sympatric flighted versus flightless lineages within a wing-polymorphic stonefly species. Our analyses of sensory responses reveal that recently-evolved flightless lineages have substantially degraded olfactory acuity. By comparing flighted versus flightless ecotypes with similar genetic backgrounds (4), we eliminate other confounding factors that might have affected the evolution of their olfactory reception mechanisms. Our detection of different patterns of degraded olfactory sensitivity and speed in independently wing-reduced lineages highlights parallel evolution of sensory degeneration. These reductions in sensory ability also echo the rapid vestigialization of wings themselves (4, 5), and represent a neurobiological parallel to the convergent phenotypic shifts seen under sharp selective gradients in other systems (e.g. parallel loss of vision in diverse cave fauna (6)). Our study provides the first direct evidence for the hypothesis that flight poses a selective pressure on the speed of olfactory receptor neurons. Our findings also emphasize the energetic costs of rapid olfaction, and the key role of natural selection in shaping dramatic neurobiological shifts.Significance StatementFlying insects move fast and have therefore evolved exceptionally quick-acting sensory systems. The speed with which such neurobiological shifts can evolve, however, remains unclear. Under the ‘use it or lose it’ hypothesis, loss of flight should lead to degradation of this fast sensory processing ability. We test for evolutionary reductions in olfactory acuity linked to flight loss, through neurobiological comparisons of flightless versus flighted lineages within a wing-polymorphic insect. Our analyses reveal that newly wing-reduced populations have substantially degraded olfactory acuity, with parallel reductions in this sensory ability detected in independently flightless lineages. These findings reveal that flight poses strong selective pressure for rapid olfaction, and highlight the potential of natural selection in rapidly shaping adaptive shifts in animal sensory systems.

The Levantine jellyfish Rhopilema nomadica and Rhizostoma pulmo swim faster against the flow than with the flow

Jellyfish locomotion and orientation have been studied in the past both in the laboratory, testing mostly small jellyfish, and in the field, where it was impossible to control the seawater currents. Utilizing an outdoor water flume, we tested the locomotion of jellyfish when swimming against and with currents of up to 4.5 cm s−1. We used adult jellyfish from two of the most abundant species in the eastern Mediterranean, Rhopilema nomadica and Rhizostoma pulmo, and measured their pulsation frequency and swimming speed relative to the water. While pulsation frequency was not affected by the water velocity, jellyfish swam faster against the current than with it. This finding suggests that jellyfish possess a sensory ability, whose mechanism is currently unknown, enabling them to gauge the flow and react to it, possibly in order to reduce the risk of stranding.

Self-report Measures of Hearing and Vision in Older Adults Participating in the Canadian Longitudinal Study of Aging are Explained by Behavioral Sensory Measures, Demographic and Social Factors

Objectives. Our objectives were to 1) determine the prevalence of self-reported hearing, vision and dual sensory (both vision and hearing) difficulties in older Canadian adults; 2) examine the association between self-report and behavioral sensory measures; and 3) controlling for behavioral sensory measures, examine variables that might explain self-reported sensory difficulty, including age, sex, cultural background, socio-economic status, non-sensory comorbidities, cognitive function, and social factors.Design. We used baseline data collected from the 30,097 participants of the comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA). Participants who were 45 to 85 years of age (mean age = 63 years) were recruited using provincial health registries and random-digit dialing. Analyses were conducted for the sample as a whole or stratified by age. Behavioral sensory data for hearing (pure-tone audiometry) and vision (pinhole-corrected visual acuity) were collected at 11 data collection sites. Self-reported sensory and personal data were obtained through in-person interviews. “Difficulty” was defined as a response of “fair” or “poor” (versus “excellent,” “very good” or “good”) to questions about a.) hearing ability (using a hearing aid if used) and b.) vision (using glasses or corrective lenses if used). Individuals with both hearing and vision difficulties were defined as having dual sensory difficulties. Variables associated with self-reported sensory difficulties were analyzed with multiple regression models.Results. Objective 1. The prevalence of impairments based on behavioral measures was higher than the prevalence of difficulties based on self-report measures. The prevalence based on both types of measures increased with age, but the increase was steeper for behavioralmeasures. Objective 2. In addition to the expected positive associations between self-report and behavioral measures of hearing (OR = 2.291) and vision (OR = 16.139), self-reported sensory difficulty was also explained by other within-modality sensory variables, such as the symmetry of impairment and the use of aids. Objective 3. Controlling for behavioral measures of hearing (better-ear pure-tone average) or vision (better-eye visual acuity), older participants were significantly less likely than younger participants to self-report sensory difficulty. Sensory difficulties were reported more often by males, and those with more comorbid health conditions. Compared to those who did not report vision difficulties, those who did report them were more likely to also report hearing difficulties (OR = 2.723) and vice versa (OR = 2.922). There were modality-specific associations with social variables; for example, independent life space was associated with hearing difficulties, and perceived availability of social support and loneliness with vision difficulties.Conclusions. The low prevalence of self-reported sensory difficulties relative to the behavioral measures of sensory impairments indicates that 1) a simple screening question about sensory ability may not be sufficient to identify older adults who are in the early stages of sensory decline, and 2) self-reported sensory ability is associated with sensory and non-sensory factors. Age, gender, and comorbidities are the most notable non-sensory predictors for both hearing and vision. These findings shed light on how the self-reported sensory difficulties of older adults may reflect clinical measures of sensory impairment as well as non-sensory factors.

Beyond Micro-Tasks

The emergence of crowdsourcing as an important mode of information production has attracted increasing research attention. In this article, the authors review crowdsourcing research in the data management field. Most research in this domain can be termed tasked-based, focusing on micro-tasks that exploit scale and redundancy in crowds. The authors' review points to another important type of crowdsourcing – which they term observational – that can expand the scope of extant crowdsourcing data management research. Observational crowdsourcing consists of projects that harness human sensory ability to support long-term data acquisition. The authors consider the challenges in this domain, review approaches to data management for crowdsourcing, and suggest directions for future research that bridges the gaps between the two research streams.

Octopuses in wild and domestic relationships

People commonly interact with terrestrial domestic animals, such as dogs and cats, horses, cattle and goats, and birds. Thereby individuals of different species form animal–human bonds. We are now forming relationships with ocean animals in increasingly common ways through growing human populations, advances in technology such as SCUBA, ocean mapping, underwater instrumentation and advances in aquatic animal husbandry. Octopuses and humans share quite distant evolutionary ties and yet share aspects of sensory ability and intelligence. Octopuses thereby pose interesting challenges and conundrums for understanding animal–human relationships. I consider several reasons to expect that the evolution of octopuses, and of animal cognition generally among active and visually sophisticated animals, will favour traits that support relationships between individuals. The evolutionary outcome of animals capable of forming inter-individual relationships may thus be expected in any evolving biota with organisms of this kind. This article explores the ability of ocean and terrestrial animals to relate to one another in ways that are reciprocal, if not equally balanced, and illustrates this with the examples of octopuses.
