A multi-modal mouse incorporating tactile and force feedback was tested in a target selection task with 12 subjects . Four feedback conditions (normal , tactile , force , tactile 1 force) were combined with three target distances and three target sizes . We found significant reductions in the overall movement times and in the time to stop the cursor after(More)
 In a previous study where reaction-time methods were combined with transcranial magnetic stimulation (TMS) of the motor cortex, cortico-spinal excitability was shown to reflect time preparation. Provided that subjects can accurately estimate time, the amplitude of motor-evoked potentials (MEPs) diminish progressively during the interval separating the(More)
This paper reviews the history of automotive technology development and human factors research, largely by decade, since the inception of the automobile. The human factors aspects were classified into primary driving task aspects (controls, displays, and visibility), driver workspace (seating and packaging, vibration, comfort, and climate), driver’s(More)
Driving assistance systems that adapt to an individual driver are essential for avoiding traffic accidents because there are individual differences in the way of driving. To realize such systems, it is necessary to take account of not only observable physical quantities, but also information inferred from observation. For example, a collision avoidance(More)
Abstract: Driving assistance systems are essential technologies to avoid traffic accidents, reduce traffic jams, and solve environmental problems. Not only observable behavioral data, but also unobservable inferred values should be considered to realize advanced driving assistance systems that are adaptable to individual drivers and situations. For this(More)
In natural situations, we can obtain sensory information in different modalities such as visual, auditory and tactile from an object. The human-computer interface with a mouse can give us both visual and kinesthetic information. However, the tactile information that occurs when we touch an object in a natural situation is not available from a mouse. In(More)
