This paper proposes a directional torque feedback technique for mobile devices that creates brief unbalanced torque by suddenly starting to rotate a stationary flywheel and then stopping it soon after. The experimental results show that a twisting sensation was induced effectively with angular velocity profiles that include sudden starts.
When a small mass in a hand-held device oscillates along a single axis with asymmetric acceleration (strongly peaked in one direction and diffuse in the other), the holder typically experiences a kinesthetic illusion characterized by the sensation of being continuously pushed or pulled by the device. This effect was investigated because of its potential… (More)
Weight perception has been of great interest for over three centuries. Most research has been concerned with the weight of static objects, and some illusions have been discovered. Here, we show a new illusion related to the perception of the heaviness of oscillating objects. We performed experiments that involved comparing the weight of two objects of… (More)
In the visual modality adaptation to high temporal frequency can result in spatially localized apparent duration compression. The principal point of adaptation is thought to be early in the visual system, at which point temporal information is encoded within sustained (parvocellular) and transient (magnocellular) channels. Here, we investigate whether the… (More)
When visually impaired pedestrians walk from one place to another by themselves, they must update their orientation and position to find their way and avoid obstacles and hazards. We present the design of a new haptic direction indicator, whose purpose is to help blind pedestrians travel a path and avoid hazards intuitively and safely by means of haptic… (More)
We developed a novel sensation interface device using galvanic vestibular stimulation (GVS). GVS alters your balance. Our device can induce vection (virtual sense of acceleration) synchronized with optic flow or musical rhythms. The device can also induce lateral walking towards the anode while human walking.
