A 2.5-D representation of the human hand
No full textPrimary somatosensory maps in the brain represent the body as a discontinuous, fragmented set of 2-D skin regions. We nevertheless experience our body as a coherent 3-D volumetric object. The links between these different aspects of body representation, however, remain poorly understood. Perceiving the body’s location in external space requires that immediate afferent signals from the periphery be combined with stored representations of body size and shape. At least for the back of the hand, this body representation is massively distorted, in a highly stereotyped manner. Here we test whether a common pattern of distortions applies to the entire hand as a 3-D object, or whether each 2-D skin surface has its own characteristic pattern of distortion. Participants judged the location in external space of landmark points on the dorsal and palmar surfaces of the hand. By analyzing the internal configuration of judgments, we produced implicit maps of each skin surface. Qualitatively similar distortions were observed in both cases. The distortions were correlated across participants, suggesting that the two surfaces are bound into a common underlying representation. The magnitude of distortion, however, was substantially smaller on the palmar surface, suggesting that this binding is incomplete. The implicit representation of the human hand may be a hybrid, intermediate between a 2-D representation of individual skin surfaces and a 3-D representation of the hand as a volumetric object
The effectiveness of origami on overall hand function after injury: A pilot controlled trial
No full textThis pilot study measured the effectiveness of using origami to improve the overall hand function of outpatients attending an NHS hand injury unit. The initiative came from one of the authors who had used origami informally in the clinical setting and observed beneficial effects. These observed effects were tested experimentally. The design was a pilot non-randomised controlled trial with 13 participants. Allocation of the seven control group members was based on patient preference. The experimental group members attended a weekly hour of origami for six weeks, in addition to their conventional rehabilitation.
Hand function of all participants was measured using the Jebsen-Taylor Hand Function Test before and after the six-week period, and additional qualitative data were gathered in the form of written evaluations from patients. The quantitative data were analysed using the Mann Whitney U test or Fisher’s exact test. Themes were highlighted from the qualitative data.
The results show that there was a greater difference in the total score of the experimental group using the impaired hand between pre- and post-intervention of 11.8 seconds, compared with 4.3 seconds in the control group, but this was not statistically significant at the 5% level (p=0.06). Additionally, differences in the sub-test scores show a markedly larger improvement in the experimental group. Qualitative data indicate that the experimental group experienced the origami sessions as being enjoyable and beneficial. Further research with a larger sample and randomised group allocation is recommended to verify and expand these preliminary findings
Hand gesture recognition using RGB-D cues
No full textIn this paper, we propose a hand gesture recognition method in the clutter background by fusing the RGB-D cues. Since the hand localization is the key issue, we propose a coarse-to-fine procedure to detect hand accurately, which combines the statistic skin model using color information with depth prior knowledge. By detecting the skin candidate regions on the color image with Gaussian Mixture Model (GMM) skin model, hand region is obtained by compounding the depth information with the assumption that hands are at the closest position to the camera in all skin regions. Then, a new descriptor based on saliency point is used to represent the binary hand properly. A new hand model containing the wrist is proposed and the gesture recognition based on special points is applied. The experiment results demonstrate that our method performs better than NMI and moment based methods with a 96.2% recognition rate. © 2012 IEEE

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Wayland D. Hand (interview)
No full textThis interview is included in the Indiana University Folklore Institute, 1987 Collection at the Indiana University Center for the Study of History and Memory. In this interview, Wayland Hand discusses his experiences with the Indiana University Folklore Institute. He outlines his educational background and his work with mentor Archer Taylor. He discusses his early involvement with Stith Thompson and his experiences attending and teaching at the IU Folklore Summer Institute for several years. He also outlines the development of other folklore groups at the time. Hand discusses the offer from Herman B Wells for the directorship of the Folklore Institute after Thompson retired, which he ultimately turned down. Hand reminisces about Stith Thompson, Richard Dorson and other Indiana University alumni he has known through the years. He also describes both Thompson's and Dorson's contributions to the success of the IU program. Hand tells several anecdotes related to the Institute and other experiences in folklore. Finally Hand compares the IU program to other folklore programs in the United States and outlines IU's strengths and weaknesses. This collection is part of the Indiana University Folklore Institute, 1987 collection which is available at the Indiana University Center for the Study of History and Memory. It consists of: 58 pages, 2 cassettes (1 7/8 ips, 120 minutes), index, subject list for Encyclopedia of American Popular Beliefs and Superstitions, and two sample articles from Encyclopedia of American Popular Beliefs and Superstitions. This collection is closed until 2015 except to authorized project personnel. The IU Folklore Institute, 1987 collection deals with the beginning, the building, and the growth of the Indiana University (IU) Folklore Institute into an internationally recognized program. The interviewees are mostly students and/or faculty of the folklore program from the 1940s to the 1980s. They discuss those who most influenced and impacted the institute, namely Stith Thompson and Richard M. Dorson. They share their memories and experiences of the time they spent, or continue to spend, in the IU Folklore Institute
