We present impacto, a device designed to render the haptic sensation of hitting or being hit in virtual reality. The key idea that allows the small and light impacto device to simulate a strong hit is that it decomposes the stimulus: it renders the tactile aspect of being hit by tapping the skin using a solenoid; it adds impact to the hit by thrusting the(More)
In this paper we present the results of a study of human preferences in using mid-air gestures for directing other humans. Rather than contributing a specific set of gestures, we contribute a set of gesture types, which together make a set of the core actions needed to complete any of our six chosen tasks in the domain of human-to-human gestural(More)
PURPOSE To identify the gene disrupted by a de novo reciprocal balanced translocation t(6;8)(q26;q13) in a patient with Duane retraction syndrome (DURS). The break point in chromosome arm 8q is positioned within the DURS1 critical region. METHODS Fluorescence in situ hybridization (FISH) analysis using cosmid and BAC clones covering the DURS1 locus was(More)
We propose a new type of tactile displays that drag a physical tactor across the skin in 2D. We call this skin drag. We demonstrate how this allows us to communicate geometric shapes or characters to users. The main benefit of our approach is that it simultaneously produces two types of stimuli, i.e., (1) it moves a tactile stimulus across skin locations(More)
Overview+Detail interfaces can be used to examine the details of complex data while retaining the data's overall context. Dynamic data introduce challenges for these interfaces, however, as moving objects may exit the detail view, as well as a person's field of view if they are working at a large interactive surface. To address this "off-view" problem, we(More)
A case of a true hermaphrodite presenting with a karyotype of 46,X,del(X)(p21.1→pter) is described. The testis-determining gene, SRY, was not detected in DNA prepared from either peripheral blood lymphocytes or from a gonad biopsy. The patient also presented with a series of discrete somatic abnormalities, including abnormal skin and retinal pigmentation,(More)
Recently, researchers started to engineer not only the outer shape of objects, but also their <i>internal microstructure</i>. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions. So far, metamaterials were understood as materials-we want(More)
We propose a new way of eyes-free interaction for wearables. It is based on the user's proprioceptive sense, i.e., rather than seeing, hearing, or feeling an outside stimulus, users feel the pose of their own body. We have implemented a wearable device called Pose-IO that offers input and output based on proprioception. Users communicate with Pose-IO(More)
Squamous cells carcinoma (SCC) is the second most frequent of the keratinocyte-derived malignancies after basal cell carcinoma and is associated with a significant psychosocial and economic burden for both the patient himself and society. Reported risk factors for the malignant transformation of keratinocytes and development of SCC include ultraviolet light(More)
