Traveller: An Interactive Cultural Training System controlled by User-Defined Body Gestures

Abstract. In this paper, we describe a cultural training system based on an interactive storytelling approach and a culturally-adaptive agent architecture, for which a user-defined gesture set was created. 251 full body gestures by 22 users were analyzed to find intuitive gestures for the in-game actions in our system. After the analysis we integrated the gestures in our application using our framework for full body gesture recognition. We further integrated a second interaction type which applies a graphical interface controlled with freehand swiping gestures

Influência do Fósforo, Micorriza e Nitrogênio no Conteúdo de Minerais de Brachiaria brizantha e Arachis pintoi Consorciados Effect of Phosphorus, Mycorrhizal and Nitrogen on Mineral Content of Brachiaria brizantha - Arachis pintoi Mixture

O experimento foi conduzido em casa de vegetação com o objetivo de avaliar a influência do fósforo (P), fungos micorrízicos arbusculares (FMA's) e nitrogênio (N) no acúmulo de minerais na MS da parte aérea de braquiária MG-4 (Brachiaria brizantha cv. MG-4) e amendoim forrageiro (Arachis pintoi cv. Amarillo) consorciados, em solo de baixa fertilidade. O delineamento utilizado foi o inteiramente casualizado, num esquema fatorial 5x2x2, sendo cinco doses de P (25, 50, 75, 100 e 200 mg de P/kg de solo), dois tratamentos de inoculação do solo (inoculado e não com o FMA Glomus etunicatum) e dois tratamentos de N (com e sem N em cobertura), com quatro repetições. Foi realizado o corte da parte aérea das plantas aos 60 dias após a germinação para a determinação das quantidades acumuladas de N, P, K, Ca, Mg e S na MS da parte aérea. As adubações fosfatada e, principalmente, a nitrogenada provocaram aumento no conteúdo de N, P, K, Ca, Mg e S na braquiária MG-4, não se verificando tal aumento com a micorrização. No amendoim forrageiro, observou-se redução destes minerais com a aplicação de N, ao passo que a micorrização resultou em aumento dos mesmos. Por outro lado, a adubação fosfatada provocou pequeno aumento no acúmulo de minerais na MS da parte aérea do amendoim forrageiro.<br>This experiment was carried out in a greenhouse condition to study the effect of phosphorus, arbuscular mycorrhizal fungi and nitrogen on mineral accumulation in braquiaria MG-4 (Brachiaria brizantha cv. MG-4) above ground forage DM and peanut (Arachis pintoi cv. Amarillo) mixture, in soil of low fertility. The experimental design was a completely randomized in a 5x2x2 factorial arrangement, with five P rates (25, 50, 75, 100 and 200 mg/kg of soil), two inoculations (inoculated and no inoculated) and two levels of N (with and without N), with four replicates. The harvest of the above ground parts of plants was at 60 days after seed germination to determine the accumulated amounts of N, P, K, Ca, Mg and S. The phosphorus and mainly the nitrogen fertilization increased the accumulation of N, P, K, Ca, Mg and S in plant DM of braquiaria MG-4, however, this was not observed for mycorrhization. For forage peanut, a reduction of these minerals was observed with application of N, whereas the mycorrhization resulted in an increase of them. On the other hand, the phosphorus caused little increase in the accumulation of minerals in plant DM of peanut forage
