Vibrotactile stimulation to the gluteal or back regions through seats is a promising approach to deliver supplemental information to humans. Designing a method to achieve pleasant vibrotactile stimuli was addressed in this study, as such stimuli tend to result in unpleasant experiences for users. In particular, we investigated the properties of continual vibrotactile stimulation to the gluteal region...
Nowadays, people have to face many challenges In order to become familiar with all the functionalities of electronical devices. The training process becomes thus essential, especially when we are referring to consumer electronics created for people with disabilities. Our paper presents the importance of training visually impaired people for an advanced sensory substitution device. By using the advantages...
When two partners perform a joint physical task, each of them experiences a force that sums together a component generated by the partner and another generated from the environment. To investigate whether subjects are able to distinguish these two components, we created a force perception task in which two partners indicate the direction of an external force applied to a rigid bar that they grasp...
Haptic guidance has previously been employed to improve human performance in control tasks. This paper presents an experiment to evaluate whether haptic feedback can be used to help humans learn a compensatory tracking task. In the experiment, participants were divided into two groups: the haptic group and the no-aid group. The haptic group performed a first training phase with haptic feedback and...
We investigated a correlation between electroencephalography (EEG) power and user satisfaction about haptic sensation. EEG power in alpha, delta, and high beta band showed a significant correlation with haptic satisfaction, especially in the early period. Our results show the feasibility of a novel metric for UI design of consumer electronics.
In this paper, we present a novel 3D interaction technique using a smartphone for large screen such as TV and projector screen. Using our 3D interaction technique, we could manipulate 3D objects in 3D environment with the virtual hand metaphor. Also, we evaluate the effects of various sensory inputs such as vibro-tactile, auditory and visual inputs. The result of the user study shows that visual feedback...
The objective of this work is to augment actual hands-on conventional vocational training workshop with simulated training using virtual haptic simulations as part of computer-based vocational education and training. We have developed a system to simulate various common tool exercises and procedures in virtual environments for vocational training programs targeted towards illiterate and semi-literate...
In this work, we propose haptic-based bilateral tele-operation for quad-rotor vehicles by using Internet communication infrastructure. The idea is to introduce shared autonomy to increase remote operation and manipulation capacity of the vehicle in uncertain flying environments. The design couples ground and remote sites by position and velocity signals of the master haptic and slave quad-rotor vehicle...
The effect of a white noise stimulus on perceived length was investigated. In contrast to our expectations, stimulus lengths presented in the radial-vertical axis were underestimated relative to those presented in the horizontal axis. Surprisingly, differing stimulus lengths and exposure times had no influence on percentage error scores, suggesting that these factors play no role in what we are calling...
Remote experiment and his quite recent extension towards remote experiment network have created a new workspace in teaching / learning environment. There is well known the fact that “environment influences behavior” (Gallagher -1993). Remote experiment has an articulated, codified and stored shape being easy to be transmitted to others. It means that remote experiment has all of the characteristics...
Telexistence technology enables a highly realistic sensation of existence in a remote place without any actual travel. The concept was originally proposed by the first author in 1980, and its feasibility has been demonstrated through the construction of alter-ego robot systems such as TELESAR & TELESAR V, which were developed under the national large scale project on “Robots in Hazardous Environments”...
This paper presents the assistive technology device called ELC (Electronic Long Cane), which was developed as a mobility aid for blind or visual impaired people. This approach comprises an ergonomic design along with an embedded electronics inside the grip of a traditional long cane, which, by mean of haptics, spreads human spatial and tactile perception. The device signalizes obstacles above waistline...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
