This critical review examines the effect of AAC assisted device screen layout on the ability of preschool children to access vocabulary. Specifically, this review compares the success of young children when using a speech generating device containing either a traditional grid organizational display, where vocabulary items are organized in a square grid pattern of discrete icons, or a Visual Sce...

We describe an efficient approach to rendering a perspectively correct image on a potentially irregular display surface that may be illuminated with one or more distinct devices. The first pass of the technique generates an image of the desired graphics model using conventional rendering. The second pass projects that image as a texture onto a model of the display surface, then re-renders the t...

In this paper, a hologram with tactile reactions is presented. The developed system consists of three components; a holographic display, a hand tracker, and a tactile display. The tactile display, which is our original device, produces force on user’s bare hand without any contact by using radiation pressure of airborne ultrasound. It adds the sense of touch to optical images floating in mid-ai...

Traditionally, a user has positioned himself/herself to be in front of a display in order to access information from it. In this information age, life at work and even at home is often confined to be in front of a display device that is the source of information or entertainment. This paper introduces another paradigm where the display follows the user rather than the user being tied to the dis...

A plethora of mobile devices such as smartphones, wearables, and tablets have been explosively penetrated into the market in the last decade. In battery powered mobile devices, energy is a scarce resource that should be carefully managed. A mobile device consists of many components and each of them contributes to the overall power consumption. This paper focuses on the energy conservation probl...

We describe a new tactile display for use in dexterous telemanipulation and virtual reality. Our system renders the changing location of a remote or virtual contact by moving a tactile element along the user’s fingertip. Mounted at the endpoint of a haptic mechanism, our thimble-sized device concurrently displays contact location and interaction forces. We believe such a design will enable more...

The benefits of using virtual environment display technology is the familiarity of the user with the modalities of that environment providing a very intuitive access to models or data sets represented by using this technology. Various different styles of input devices are typically used for such virtual environments, ranging from standard game-pads to high-end commercial devices like an A.R.T. ...

This paper presents an experiment of two finger grasping. The task considered is the peg-in-hole and the simulated force feedback is cutaneous or kinesthetic. The kinesthetic feedback is provided by a commercial haptic device while the cutaneous one is provided by a new haptic display proposed in this work, which allows to render at the fingertip a wide range of contact forces. The device consi...
