- Digitally augmenting the physical ground space with timed visual cues for crutch-assisted walkingPublication . Peres, Beatriz; Campos, Pedro; Azadegan, AidaThis late-breaking work presents initial results regarding a novel mobile-projection system, aimed at helping people to learn how to walk with crutches. The existing projection-based solutions for gait training disorders are based on walking over a fixed surface (usually a treadmill). In contrast, our solution projects visual cues (footprints and crutch icons) directly into the floor, augmenting the physical space surrounding the crutches, in a portable way. Walking with crutches is a learning skill that requires continuous repetition and constant attention to detail to make sure they are being used correctly, avoiding negative consequences, such as falls or injuries. We conducted expert consultation sessions, and we identified the main issues that patients face when walking with crutches. This informed the design of Augmented Crutches. We performed a qualitative evaluation and conclude with design implications: the importance of timing, self-assurance and awareness.
- A digitally-augmented ground space with timed visual cues for facilitating forearm crutches’ mobilityPublication . Peres, Beatriz; Campos, Pedro; Azadegan, AidaPersuasive technologies for physical rehabilitation have been pro posed in a number of different health interventions such as post-stroke gait rehabilitation. We propose a new persuasive system, called Augmented Crut ches, aimed at helping people to walk with crutches. People with injuries, or with any sort of mobility problem typically use assistive devices such as crut ches, 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 Crut ches 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.
