Interfacing and Control of Artificial Hands

Unknown Date (has links)
This thesis discusses three projects that revolve around the central concept of the control of artificial hands. The first part of the thesis discusses the design of a museum exhibit for the South Florida Science Center that allows the public to control an i-limb Revolution prosthetic hand using electromyograph (EMG) sensors. A custom armature was designed to house the EMG sensors that are used to control the prosthesis. The top arm of the armature utilized a double rocker design for a greater range of motion which allows the display to accommodate arm sizes ranging from small children to large adults. This display became open to the public in March of 2019. The second part of the thesis describes a new concept for a simultaneous multi-object grasp using the Shadow hand robotic hand. This grasp is tested in an experiment that involves grasp and transportation tasks. This experiment also aims to analyze the benefit of soft robotic haptic feedback armband during the grasp and transportation tasks when a simulated break threshold is imposed on the objects. The usefulness of the haptic feedback was further tested with a guess the object task where the subjects had to determine which object was in the hand based solely off the armband. The new grasp synergy was deemed a success as all subjects were able to use the control method effectively with very little initial training. It was also found that the haptic feedback greatly aided in the successfully completing the transportation tasks. The human subjects were asked to rate the haptic feedback after each task, the overall rating for the helpfulness of the haptic feedback was rated as 4.6 out of 5. The final part of the thesis discusses an approach at gaining additional control signals for a dexterous artificial hand using a brain computer interface. This project seeks to investigate three neuromarkers for control which are: mu, xi and alpha. During analysis, the mu rhythm was not seen in our subject but alpha and xi were. Using deep learning approaches at classification, we were able to classify alpha and xi with at least a 90 percent accuracy. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection

Designing Organic User Interfaces

Holman, DAVID 23 January 2014 (has links)
With the emergence of flexible display technologies, graphical user interfaces will no longer be limited to flat surfaces. As such, it will become necessary for interface designers to move beyond flat display designs, contextualizing interaction in an object’s physical shape. Grounded in early explorations of Organic User Interfaces (OUIs), this thesis examines the evolving relationship between industrial and interaction design and argues that not only what, but how we design is changing. To understand how to better design OUIs, we report on an empirical study of pointing behavior that shows how Fitts’ law can model movement time on an extremely convex surface. We also show that touch sensing technology can be repurposed for the OUI design process by making it possible to tape, draw, or paint touch sensing directly on a physical prototype. We then discuss how supporting sketching, a fundamental activity of many design fields, is increasingly critical for the interactive three-dimensional forms in OUI and that a ‘hypercontextualized’ approach to their design can reduce the drawbacks met when everyday objects become interactive. Finally, we discuss that when interactive hardware is seamlessly melded into an object’s shape, the ‘computer’ disappears. When designing OUIs, it is better seen as a basic material, like the clay, foam core, or plastics used by an industrial designer, and one that happens to have interactive potential. / Thesis (Ph.D, Computing) -- Queen's University, 2014-01-23 12:00:08.953

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2005. / Made available in DSpace on 2013-07-15T23:53:52Z (GMT). No. of bitstreams: 1 275539.pdf: 279587 bytes, checksum: 036ed0813a49ea0f1361467429077016 (MD5) / O acesso universal às informações na Internet, independente da origem, da condição física ou do dispositivo que o usuário utiliza, pode ser alcançado com a adoção dos padrões web no processo de design das interfaces dos meios nos quais as informações são apresentadas. A correta utilização dos padrões proporciona também outras vantagens, dentre as quais se destaca o aumento da produtividade da equipe envolvida responsável pelo desenvolvimento. Entretanto, não existem modelos para o desenvolvimento de interfaces que contemplem a adoção de tais padrões. Além disso, os modelos existentes não contemplam todas as fases do projeto de interfaces. Em geral, não mencionam a etapa de implementação. Dada a situação, o presente trabalho propôs-se a realizar a busca por um modelo que contemplasse todas as fases que compõe o processo de design de interfaces e que ao mesmo tempo considerasse a adoção dos padrões. Para isso, foi selecionado um modelo existente, utilizado em larga escala na área de IHC (Interface Homem-Computador), para ser utilizado no projeto de uma aplicação que adotou os padrões web. A partir da análise do projeto foi possível afirmar o grau de adaptabilidade do modelo selecionado frente à busca por um modelo integrado que adota os padrões web, e foi descartada a necessidade de concepção de um novo modelo.
