The growing needs in the area of HCI has led to many new researches focusing on user-centric design, investigating the problems faced by a computer user and ways to produce an effective yet efficient design. Often, designers need to acquire the knowledge and the experience of the users to produce a good interface design. This can be referred as a wise exploitation of user's mental model. The paper serves as a preliminary study which explores the mental model of blind users as a contribution in improving the accessibility of computer applications. Based on the blind user's perception, imagination and interpretation, the study indicates that touch sensation plays an important role in improving the representation of a computer application to them. Associating touch sensation with information familiar to the blind users enhances the learning process.

“…When a user touches a GUI component like a graphical "button" drawn on an LCD display, he/she feels a realistic tactile sensation as if he/she touches or pushes a real button. The device presents such tactile sensation by vibrating the whole screen [2]. The hardware structure and tactile stimuli generation mechanism of the device are described in Section 3.C.…”

Recently, the progresses of human-computer interface technology implemented on tablet PCs (personal computers) enables medical workers to utilize them for communications between patients and doctors at the time of condition analysis and diagnosis. Because general patients cannot understand medical images alone, the technology assists them to intuitively understand the images and easily communicate with doctors. We propose a tangible medical image processing assistant with haptic modality. Our main goal is to construct a method allowing users to easily interacting and exploring medical images with haptic modality. Diagnostic imaging with a series of CT scan images is very important way for doctors to detect problems. Because the doctors need to view a huge number of high resolution images in a day, excessive burdens on their vision become a very serious problem. We propose a new method of assisting the diagnostic imaging with integrated visual and haptic channels. The proposed method extracts some visual features observed in the images and transforms to haptic parameters. Then, the system visually and haptically notifies the doctors for possible existence of suspicious findings in the images. It calls their attention to focus on the specific images to narrow the differential diagnosis of the images.

“…In recent years we have been witnesses to a rapid evolution in the fields of human-X interaction, where X could be machine, computer, intelligent device, etc. A common feature in many novel assistive and rehabilitation applications [1][2][3] and in most hand-held personal informatics devices [4][5][6][7] is vibration-based notification or more sophisticated tactile feedback. In these devices, vibration capability is usually implemented using eccentric rotating mass (ERM) actuators (1-degree of freedom (DoF) approach) composed of a DC micromotor with an eccentric rotor, or the so-called shaftless vibration motor [8].…”

Vibration actuators are widely used in handheld devices to provide vibrotactile feedback or silent notification to the users. In most cases, miniature DC motors with eccentric rotors or the so-called coin-type shaftless vibration motors are utilized. The common disadvantage of the single rotor designs is that the frequency and the intensity of the generated vibration cannot be adjusted separately. The construction composed of two independently driven coaxial eccentric rotors -which makes a strongly coupled nonlinear system -allows for the separate control of the frequency and amplitude by the adjustment of the angular speed and the total eccentricity. This paper presents a complete control design approach based on quasi-linear parameter varying (qLPV) modelling and linear matrix inequality (LMI)-based synthesis utilizing the tensor product (TP) model transformation to determine the convex polytopic representation of the parameter dependent nonlinear system. The design approach is demonstrated via a concrete numerical example using the parameters of a real dual-excenter prototype device. The control performance is validated through numerical simulations. This case study goes through a complete nonlinear control problem from the modelling phase to the implementation-ready controller, while drawing generalizable conclusions for qLPV modelling.
