“…The larger the window length, the smaller the variance of the velocity is. This is equivalent to averaging the last velocity estimates, , with obtained from the finite difference method (2) (12) Provided that the signal is well represented by its samples, increasing the window size is equivalent to decreasing the sampling rate. A large window introduces time delay and also reduces the estimation reliability.…”

We present methods for velocity estimation from discrete and quantized position samples using adaptive windowing. Previous methods necessitate tradeoffs between noise reduction, control delay, estimate accuracy, reliability, computational load, transient preservation, and difficulties with tuning. In contrast, a first-order adaptive windowing method is shown to be optimal in the sense that it minimizes the velocity error variance while maximizes the accuracy of the estimates, requiring no tradeoff. Variants of this method are also discussed. The effectiveness of the proposed technique is verified in simulation and by experiments on the control of a haptic device.

“…In the first case, the collision vector can be obtained directly form the measured distance vector as shown in Fig. 4(a), and it is represented as C=L.min The relation between the mobile robot and obstacles is modeled by springs and dampers to generate the virtual force adopting the general impedance algorithm [9]. However, a collision vector is newly introduced in this paper to define the direction of the virtual spring as well as the virtual damper as the variation of the collision vector, which improves the collision avoidance performance dramatically.…”

Though the final goal of mobile robot navigation is to be autonomous, operators' intelligent and skillful decisions are necessary when there are many scattered obstacles. There are several limitations even in the camera-based tele-operation of a mobile robot, which is very popular for the mobile robot navigation. For examples, shadowed and curved areas cannot be viewed using a narrow view-angle camera, especially in bad weather such as on snowy or rainy days. Therefore, it is necessary to have other sensory information for reliable tele-operations. In this paper, sixteen ultrasonic sensors are attached around a mobile robot in a ring pattern to measure the distances to obstacles. A collision vector is introduced in this paper as a new tool for obstacle avoidance, which is defined as a normal vector from an obstacle to the mobile robot. Based on this collision vector, a virtual reflection force is generated to avoid the obstacles and then the reflection force is transferred to an operator who is holding a joystick to control the mobile robot. Relying on the reflection force, the operator can control the mobile robot more smoothly and safely. For this bi-directional tele-operation, a master joystick system using a hall sensor was designed to resolve the existence of nonlinear sections, which are usual for a general joystick with two motors and potentiometers. Finally, the efficiency of a force reflection joystick is verified through the comparison of two vision-based tele-operation experiments, with and without force reflection.

“…Video game consoles have long been supporting "force feedback" joysticks and other input devices since early works in the second half of the 90's. Ouhyoung and co-authors 32 presented a game-like flight simulator with vibration feedback in 1995. In 1997 Nintendo released the Rumble Pak, an accessory to connect to the Nintendo 64 joystick to produce tactile feedback.…”

Abstract:Mobile phones are a widespread platform for ICT applications because they are highly pervasive in contemporary society. Hence, we can think of mobile gaming as a serious candidate to being a prominent form of entertainment in the near future. However, most games (for computers, console and mobile devices) make extensive use of the visual medium, which tends to exclude visually-impaired users from the play. While mobile gaming could potentially reach many visually-impaired users, who are very familiar with this technology, currently there seems to be only very few alternatives for this community. In an attempt to explore new interactive possibilities for such users, this work presents an initial study on non-visual interfaces for mobile phone games. It is based on Semiotic Engineering principles, emphasizing communication through aural, tactile and gestural signs, and deliberately excluding visual information. Results include a number of issues that can be incorporated to a wider research agenda on mobile gaming accessibility, both for the visually-impaired and sighted.
