“…As a result, force-feedback rotary controllers are found only where this can be tolerated: car dashboards, piloting systems, professional audio/video editors, robot controls and medical devices. Most such controllers make use of DC motors to generate force feedback [3,25,13]. Hybrid solutions that combine motors and brakes have been proposed as well [6]: while allowing the design of subtle effects, they further increase hardware complexity.…”

Touchscreens today represent the most versatile solution for configuring user interfaces. A toll for this versatility is the intangibility of the displayed virtual controls. The addition of haptic feedback can improve their manipulation by reinforcing or even substituting visual information. While haptic rendering of virtual buttons is advancing, tangible knobs seem yet to come, possibly due to the inherent difficulty to conceptualize rotation as an interaction primitive in absence of a physical control. To address this issue, we propose a hybrid solution consisting in an endless knob with programmable resistance to rotation. Compared to existing related devices, it minimizes costs, encumbrance and power consumption, making its installation also possible on portable equipment. After describing its design and main features, we present a test which assessed how haptic feedback rendered by the knob affects performance in a visual target-matching task: users had to select targets placed on a horizontal slider by dragging its cursor through knob rotation. Results show that haptic augmentation significantly improved target acquisition.

“…Force-feedback rotary controllers can be found in many contexts, including car dashboards, piloting systems, audio/video editors, robot controls, medical devices, household and professional appliances. Most of them make use of DC motors to generate force feedback [16,15,17]. The use of such motors enables complex actuation, such as bouncing effects, at affordable costs.…”

Live music performances and music production often involve the manipulation of several parameters during sound generation, processing, and mixing. In hardware layouts, those parameters are usually controlled using knobs, sliders and buttons. When these layouts are virtualized, the use of physical (e.g. MIDI) controllers can make interaction easier and reduce the cognitive load associated to sound manipulation. The addition of haptic feedback can further improve such interaction by facilitating the detection of the nature (continuous / discrete) and value of a parameter. To this end, we have realized an endless-knob controller prototype with programmable resistance to rotation, able to render various haptic effects. Ten subjects assessed the effectiveness of the provided haptic feedback in a target-matching task where either visual-only or visual-haptic feedback was provided; the experiment reported significantly lower errors in presence of haptic feedback. Finally, the knob was configured as a multi-parametric controller for a real-time audio effect software written in Python, simulating the voltage-controlled filter aboard the EMS VCS3. The integration of the sound algorithm and the haptic knob is discussed, together with various haptic feedback effects in response to control actions.

“…La principal característica a valorar de este enfoque es que se prescinde de la fase de programación, por lo que se puede pasar del diseño a la experimentación de manera automática permitiendo dedicar más tiempo a los objetivos del aprendizaje. Existen trabajos en los que se usa Simulink para MDE en robótica [4,5], los haptics [6] y también, como en este caso a la educación [7], si bien no son muchos los estudios comparativos de herramientas como [8] o [9] y menos sobre la eficiencia de ambos enfoques en la educación superior.…”

En este trabajo se muestra la experiencia de usar una herramienta de desarrollo de ingeniería basada en modelos (MDE) frente a otra herramienta tradicional de programación de sistemas embebidos en lenguaje C, para la realización de clases prácticas de robótica. Se ha planteado una práctica basada en el control cinemático de un robot móvil en ambos entornos con similares bloques y funciones de partida. Los resultados muestran tanto la comparación de las evaluaciones objetivas realiza- das a los dos grupos como los datos relativos a los tiempos requeridos para la realización de las diferentes partes de la práctica. Si bien, los resultados del aprendizaje son mayores en el caso del método basado en programación, la diferencia en tiempos invertidos y otras valoraciones hacen más adecuado el MDE.
