Estratificação da interação com o utilizador em ambientes de Realidade Virtual

A evolução tecnológica tem sido de tal ordem que a realidade virtual deixou de ser um mero conceito que apenas é possível de implementar recorrendo a máquinas com um poder de processamento muito elevado. Tendo em conta o potencial da realidade virtual e a não existência de boas práticas na criação da interface de um sistema que use este conceito, pretende-se, nesta dissertação, fazer um estudo sobre como pode ser analisada e estruturada a componente de interação através da estratificação de níveis de interação para as diferentes operações do sistema pretendido. Por forma a ser possível, posteriormente, comparar cada um dos sistemas relativamente à interação, foram estipulados um conjunto de ações/operações que teriam de ser passíveis de executar em cada um, bem como, um tema base, uma aplicação de realidade virtual de simulação de espaço aplicada ao sector mobiliário. Depois de implementados os sistemas, estes foram apresentados a um conjunto de pessoas que foram inquiridas sobre os mesmos, por forma a avaliar a interação com cada um. Através dos resultados obtidos da avaliação dos inquéritos entregues, foi possível concluir que, para uma grande parte das operações implementadas, existe uma preferência para que a realização da operação seja o mais similar à sua execução num contexto real.

Ontario Tender Fruit Grower’s Marketing Board Fonds, 1960, 1967, 1969-1977, 1980-1981, 1987

The Ontario Tender Fruit Marketing Board operates under the Farm Producers Marketing Act. It covers all tender fruit farmers who produce either fresh or canned products. Today the board has over 500 grower-members. Tender fruit in the Niagara region includes: peaches, pears, plums, grapes and cherries. The fruits are used in a number of different ways, from jams and jellies to desserts, sauces and wine. Peaches were first harvested along the Niagara river in 1779. Peter Secord (Laura Secord’s uncle) is thought to be the first farmer to plant fruit trees when he took a land grant near Niagara in the mid 1780s. Since the beginnings of Secord’s farm, peaches, pears and plums have been grown in the Niagara region ever since. However, none of the original varities of peach trees remain today. Peaches were often used for more than eating by early settlers. The leaves and bark of the tree was used to make teas for conditions such as chronic bronchitis, coughs and gastritis. Cherries have been known to have anti-inflammatory and pain relieving properties. Like peaches and cherries, pears had many uses for the early pioneers. The wood was used to make furniture. The juice made excellent ciders and the leaves provided yellow dyes. Plums have been around for centuries, not only in the Niagara region, but throughout the world. They have appeared in pre-historic writings and were present for the first Thanksgiving in 1621. The grape industry in Ontario has also been around for centuries. It began in 1798 when land was granted to Major David Secord (brother-in-law to Laura Secord) slightly east of St. David’s, on what is Highway No. 8 today. Major Secord’s son James was given a part of the land in 1818 and in 1857 passed it onto Porter Adams. Adams is known to be the first person to plant grapes in Ontario1. Tender fruits are best grown in warm temperate climates. The Niagara fruit belt, stretching 65km from Hamilton to Niagara on the Lake, provides the climate necessary for this fruit production. This belt produces 90% of Ontario’s annual tender fruit crop. It is one of the largest fruit producing regions in all of Canada.

Pelham Cares Inc. fonds, 1980-2015

The beginnings of Pelham Cares occurred in 1982 when the Mayor of Pelham, Eric Bergenstein, received a letter from Janet Hassall, a social worker with Niagara Regional Home Care. Hassall requested that a Social Service Committee be established in Pelham to address gaps in community services, a practice that several other communities in the Region had adopted. Such committees were commonly composed of church parishioners, so Bergenstein contacted Canon J. Nowe of the Holy Trinity Anglican Church, who expressed an interest in participating in such a committee. Bergenstein arranged a meeting in June, 1982 at the United Church Hall in Fonthill, for any interested parties to learn more about the existing Social Service Committees in the Region. The meeting was not part of a Town Council project, but rather an initiative undertaken by Mayor Bergenstein in a personal capacity. Subsequent meetings chaired by Eric Bergenstein were held throughout the remainder of that year, during which the name of Pelham Cares was decided, a steering committee established, and services to be offered were determined. These initially included “visits with the lonely, the shut-ins, at home, hospital or on an outing ; run errands for those who are “stuck”; step in, in emergencies, or regularly, to free a parent or spouse who can’t otherwise get a “break”; in emergencies, provide food, clothing, furniture, medicine and other necessities”. The first official meeting of Pelham Cares occurred in January 1983. Currently, the main services offered by Pelham Cares are a food bank; transportation services to medical appointments; and sponsorship programs to allow youth with limited financial means to participate in sports, recreational and educational activities. The organization also provides emergency food, supplies or short term accommodation due to fire or other catastrophic loss, as well as providing referrals to appropriate organizations or agencies. Pelham Cares is dependent on the funding from community partners such as service clubs, citizens, local businesses, financial institutions and churches. These services are provided by volunteers and one part-time employee. A permanent location for Pelham Cares was established in 2014 with the purchase of a property on Highway 20 East in Fonthill, after a 30 years search for a permanent facility.
