Children-Robot Interaction: Eye Gaze Analysis of Children with Autism During Social Interactions

Background: Typical developing individuals utilize the direction of eye gaze and eye fixation/shifting as crucial elements to transmit socially relevant information (e.g. like, dislike) to others. Individuals with Autism Spectrum Disorder (ASD), deviant pattern of mutual eye gaze is a noticeable feature that may be one of the earliest (detectable) demonstrations of impaired social skills that would lead to other deficits in ASD Individuals (e.g. delaying development of social cognition and affective construal processes). This can significantly affect the quality of human’s social interactions. Recent studies reveal that children with ASD have superior engagement to the robot-based interaction, and it can effectively trigger positive behaviors (e.g. eye gaze attention). This suggests that interacting with robots may be a promising intervention approach for children with ASD. Objectives: The main objective of this multidisciplinary research is to utilize humanoid robot technology along with psychological and engineering sciences to better improve the social skills of children with High Functioning Autism (HFA). The designed intervention protocol focuses on different skillsets, such as eye gaze attention, joint attention, facial expression recognition and imitation. The current study is designed to evaluate the eye gaze patterns of children with ASD during verbal communication with a humanoid robot. Methods: Participants in this study are 13 male children ages 7-17 (M=11 years) diagnosed with ASD. The study employs NAO, an autonomous, programmable humanoid robot from Aldebaran Robotics to interact with ASD children in a series of conversations and interactive games across 3 sessions. During different game segments, NAO and children exchange stories and having conversation on different context. During every session of the game, four cameras which were installed in the video capturing room in addition to the NAO’s front-facing camera record the entire interaction. Videos were later score to analyze the gaze patterns of the children for two different context. Studying eye gaze fixation and eye gaze shifting while: 1) NAO is talking, 2) Kid is talking. Results: In order to analyze the eye gaze of participants, every frame of video was manually coded as Gaze Averted(‘0’) or Gaze At(‘1’) w.r.t NAO. To accurately analysis the gaze patterns of children during the conversation, the video segments of ‘NAO Talking’ and ‘Kid Talking’ have been selected. The averages of four measures were employed to report the static and dynamic properties of eye gaze patterns: 1) ‘NAO talking’: Gaze At NAO (GAN)= %55.3, Gaze Shifting (GS) =%3.4, GAN/GS = 34.10, Entropy GS: 0.20 2) ‘Kid talking’: GAN = %43.8, GS=%4.2, GAN/GS = 11.6, Entropy GS = 0.27 Conclusions: The results indicates that the children with ASD having more eye contact and less gaze shifting while NAO is talking (Higher GAN/GS and lower Entropy GS), however they prefer to shift their gaze more often and have less fixation on the robot as they are speaking. These results will serve as an important basis to significantly advance the emerging field of robot-assisted therapy for children with ASD

Solid phosphoric acid catalysts based on mesoporous silica for levoglucosenone production via cellulose fast pyrolysis

Biochemicals are interesting alternatives for biomass valorization owing to their much higher added value compared to biofuels and energy products. Several methods for the production of valuable chemicals such as levoglucosenone (LGO) via thermochemical processes over solid acid catalysts are being investigated due to their important advantages compared to conventional biomass acid impregnation techniques. The present work explores the synthesis of catalytic materials for the production of this platform molecule.Fil: Santander, José Anibal. Consejo Nacional de Investigaciones Científicas y Técnicas.

How Children with Autism Spectrum Disorder Recognize Facial Expressions Displayed by a Rear-Projection Humanoid Robot

Background: Children with Autism Spectrum Disorder (ASD) experience reduced ability to perceive crucial nonverbal communication cues such as eye gaze, gestures, and facial expressions. Recent studies suggest that social robots can be used as effective tools to improve communication and social skills in children with ASD. One explanation has been put forward by several studies that children with ASD feel more contented and motivated in systemized and predictable environment, like interacting with robots. Objectives: There have been few research studies evaluating how children with ASD perceive facial expression in humanoid robots but no research evaluating facial expression perception on a rear-projected (aka animation-based) facially-expressive humanoid robot, which provide more life-like expressions. This study evaluates how children with high functioning autism (HFA) differ from their typically developing (TD) peers in recognition of facial expressions demonstrated by a life-like rear-projected humanoid robot, which is more adjustable and flexible in terms of displaying facial expressions for further studies. Methods: Seven HFA and seven TD children and adolescents aged 7-16 participated in this study. The study uses Ryan, a rear-projection, life-like humanoid robot. Six basic emotional facial expressions (happy, sad, angry, disgust, surprised and fear) with four different intensities (25%, 50%, 75% and 100% in ascending order) were shown on Ryan’s face. Participants were asked to choose the expression they perceived among seven options (six basic emotions and none). Responses were recorded by a research assistant. Results were analyzed to obtain the accuracy of facial expression recognition in ASD and TD children on humanoid robot face. Results: We evaluated the intensity of expression in which participants required to reach the peak accuracy. They were best for happy and angry expressions in which the peak accuracy of 100% was reached with at least 50% of expression intensity. The same peak accuracy was reached for surprised and sad expressions in the intensity of 75% and 100%, respectively. But fear and disgust recognition accuracy never reached above 75%, even in the maximum intensity. The experiment is still in progress for TD children. Results will be compared to a TD sample and implication for intervention and clinical work will be discussed. Conclusions: Overall, these results show that children with ASD recognize negative expressions such as fear and disgust with a slightly lower accuracy than other expressions. On the other hand, during the test, children showed engagement and excitement toward the robot. Besides, most of the expressions were sufficiently recognizable for children in higher intensities, which means, Ryan, a rear projected life-like robot could be able to successfully communicate with children in terms of facial expression, though more investigations and improvements should be done. These results serve as a basis to advance the promising field of socially assistive robotics for autism therapy

Impacto del uso de energia en el sector industrial de Chile; una estimacion a traves de funciones de produccion

72 p.La presente investigación tiene como objetivo determinar el impacto del uso de energía en el sector industrial de Chile, entendiendo para efectos de este estudio el uso de energía como el uso de electricidad, a través de una estimación de funciones de producción para la industria como un todo y para cada sector de ésta. Para llevar a cabo lo anterior es necesario determinar la participación relativa de la energía en base a una regresión. Para saber cuáles variables incluir en el modelo se hizo una revisión bibliográfica acerca de las funciones de producción, temas relacionados con la energía y sector manufacturero de Chile, así como también para conocer lo que se ha estudiado previamente por otros autores. Luego se recopila la información pertinente para la investigación de las bases de datos del Instituto Nacional de Estadísticas (INE), específicamente fueron extraídos desde la Encuesta Nacional Industrial Anual (ENIA) para el periodo 1998 – 2006. En cuanto a la metodología, la estimación de los coeficientes y por ende de las participaciones relativas de los factores de producción se realizó mediante una regresión lineal en base a una generalización de una función de producción del tipo Cobb - Douglas, lo que permitió determinar para cada factor productivo su nivel de significancia. Se obtiene como conclusión que para algunos sectores como fabricación de maquinarias y equipos, y fabricación de maquinarias y aparatos eléctricos la energía no tienen un impacto significativo en sus niveles de producción, por lo que ésta representa para ellos una contribución al proceso de manufactura, más que un factor productivo relevante a ser comparado como lo son para la industria las materias primas y el empleo. Para sectores como fabricación de metales comunes, fabricación de otros productos minerales no metálicos, y fabricación de sustancias y productos químicos; fabricación de productos de la refinación del petróleo existe una contribución más activa del uso de la energía en los niveles de producción

Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize

Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in long-term experiments with different P fertilization in a Mollisol and a Vertisol: i) the changes of soil P fractions, and ii) the relationship between soil P fractions with long-term P fertilization, accumulated apparent P budget, grain P, total P uptake, soybean (Glycine max L.Merr.) and maize (Zea mays L.) grain yield. Soil P fractions were measured after 1 and 9 yr since the beginning of long-term experiments. Experiments included an initial fertilization rate of 200 kg P ha-1, and annual P fertilization rate of 36 kg P ha-1. Bray1-P, total, organic, and inorganic P in fine (53μm) (CF) soil fractions, and in NaHCO3 extract were measured. Initial P fertilization increased inorganic and total P fractions. Whereas, Bray1-P, total P in NaHCO3 extract and in the CF were the fractions with most increased with continuous long-term P fertilization in both sites. In the Mollisol, maize grain yield was unrelated to long-term P fertilization. In the Vertisol, total P in NaHCO3 extract, and total and organic P in the CF were more closely related to soybean grain yield than Bray1-P. We proposed soil P indices of labile inorganic and organic P that showed close relationships with soybean grain yield and may be useful to improve the diagnosis of P soil fertility.EEA ParanáFil: Appelhans, Estefania Carolina.

Using Robots as Therapeutic Agents to Teach Children with Autism Recognize Facial Expression

Background: Recognizing and mimicking facial expressions are important cues for building great rapport and relationship in human-human communication. Individuals with Autism Spectrum Disorder (ASD) have often deficits in recognizing and mimicking social cues, such as facial expressions. In the last decade several studies have shown that individuals with ASD have superior engagement toward objects and particularly robots (i.e. humanoid and non-humanoid). However, majority of the studies have focused on investigating robot’s appearances and the engineering design concepts and very few research have been done on the effectiveness of robots in therapeutic and treatment applications. In fact, the critical question that “how robots can help individuals with autism to practice and learn some social communicational skills and applied them in their daily interactions” have not been addressed yet. Objective: In a multidisciplinary research study we have explored how robot-based therapeutic sessions can be effective and to some extent they can improve the social-experiences of children with ASD. We developed and executed a robot-based multi-session therapeutic protocol which consists of three phases (i.e. baseline, Intervention and human-validation sessions) that can serve as a treatment mechanism for individuals with ASD. Methods: We recruited seven (2F/5M) children 6-13 years old (Mean=10.14 years), diagnosed with High Functioning Autism (HFA). We employed NAO, an autonomous programmable humanoid robot, to interact with children in a series of social games for several sessions. We captured all the visual and audio communications between NAO and the child using multiple cameras. All the capturing devices were connected to a monitoring system outside of the study room, where a coder observed and annotated the responses of the child online. In every session, NAO asked the child to identify the type of prototypic facial expression (i.e. happy, sad, angry, and neutral) shown on five different photos. In the ‘baseline’ sessions we calculated the prior knowledge of every child about the emotion and facial expression concepts. In the ‘intervention’ sessions, NAO provides some verbal feedback (if needed), to help the child identify the facial expression. After finishing the intervention sessions, we included two ‘human-validation’ sessions (with no feedback) to evaluate how well the child can apply the learned concepts when a human is replaced with NAO. Results: The following Table demonstrates the mean and Standard Deviation (STD) of face recognition rates for all subjects in three phases of our study. In our experiment six out of seven subjects had baseline recognition rate lower than 80% and we observed high variation (STD) between different subjects. Facial Expression Recognition Rate (%) Baseline Intervention Human-Validation Mean (STD) 69.52 (36.28) 85.83 (20.54) 94.28 (15.11) Conclusions: The results demonstrate the effectiveness of NAO for teaching and improving facial expression recognition (FER) skills by children with ASD. More specifically, in the baseline, the low FER rate (69.52%) with high variability (STD=36.28) demonstrate that overall, participants had difficulty recognizing expressions. The statistical results of intervention phase, confirms that NAO can teach children recognizing facial expressions reliably (higher accuracy with lower STD). Interestingly, in the human-validation phase children could even recognize the basic facial expressions with a higher accuracy (94%) and very limited variability (STD = 15.11). These results conclude that robot-based feedback and intervention with a customized protocol can improve the learning capabilities and social skills of children with ASD
