Abstract(s)
Tecnologias persuasivas para reabilitação física têm sido propostas em várias
intervenções de saúde diferentes, como a reabilitação da marcha pós AVC. Propomos
um novo sistema de persuasão, chamado Augmented Crutches, com o objetivo de
ajudar as pessoas a aprender a andar com canadianas. Pessoas com lesões, ou com
qualquer tipo de problema de mobilidade, geralmente usam dispositivos auxiliares,
como canadianas, andarilho ou bengalas, para poderem andar de forma mais
independente. No entanto, caminhar com canadianas é uma habilidade que necessita
de repetição contínua e atenção constante aos detalhes para que o utilizador possa
andar corretamente com elas sem sofrer consequências negativas, como quedas ou
lesões. Em colaboração com fisioterapeutas, identificamos os principais problemas que
os pacientes enfrentam quando andam com canadianas. Estes variam de pessoa para
pessoa, mas os desafios mais comuns e mais difíceis são a posição e coordenação das
canadianas. Augmented Crutches estuda os aspetos do comportamento humano nessas
situações e aumenta o espaço em torno do utilizador com elementos visuais digitais,
onde o timing é o fator mais importante, sem a necessidade de um fisioterapeuta
constantemente fornecendo ajuda manual. Isto é feito através de um mini-projetor
ligado a um smartphone, usado de forma leve e portátil. O sistema ajuda as pessoas a
aprender a andar usando canadianas com maior autoconfiança e motivação. Além disso,
o nosso trabalho identifica o tempo, a controlabilidade e a consciencialização como as
principais dimensões do design para a criação bem-sucedida de experiências persuasivas
e interativas para aprender a andar com canadianas.
Persuasive technologies for physical rehabilitation have been proposed in a number of different health interventions such as post-stroke gait rehabilitation. We propose a new persuasive system, called Augmented Crutches, aimed at helping people to learn how to walk with crutches. People with injuries, or with any sort of mobility problem typically use assistive devices such as crutches, walkers or canes in order to be able to walk more independently. However, walking with crutches is a learning skill that needs continuous repetition and constant attention to detail in order to walk correctly with them and without suffering negative consequences, such as falls or injuries. In close collaboration with therapists, we identify the main issues that patients face when walking with crutches. These vary from person to person, but the most common and hardest challenges are the position and coordination of the crutches. Augmented Crutches studies human behavior aspects in these situations and augments the ground space around the user with digital visual cues where timing is the most important factor, without the need for a constant therapist providing manual help. This is performed through a mini-projector connected to a smartphone, worn by the user in a portable, lightweight manner. Our system helps people to learn how to walk using crutches with increased self-confidence and motivation. Additionally, our work identifies timing, controllability and awareness as the key design dimensions for the successful creation of persuasive, interactive experiences for learning how to walk with crutches.
