Hand Image

In this study, we aim to construct a perception-based shape display system to provide users with the sensation of touching virtual objects of varying shapes using only a simple mechanism. Thus far, we have proved that identified curved surface shapes or edge angles can be modified by displacing the visual representation of the user's hand. However, using this method, we cannot emulate multifinger touch, because of spatial unconformity. To solve this problem, we focus on modifying the identification of shapes using two fingers by deforming the visual representation of the user's hand. We devised a video see-through system that enables us to change the perceived shape of an object that a user is touching visually. The visual representation of the user's hand is deformed as if the user were handling a visual object; however, the user is actually handling an object of a different shape. Using this system, we conducted two experiments to investigate the effects of visuo-haptic interaction and evaluate its effectiveness. One is an investigation on the modification of size perception to confirm that the fingers did not stroke the shape but only touched it statically. The other is an investigation on the modification of shape perception for confirming that the fingers dynamically stroked the surface of the shape. The results of these experiments show that the perceived sizes of objects handled using a thumb and other finger(s) could be modified if the difference between the size of physical and visual stimuli was in the −40% to 35% range. In addition, we found that the algorithm can create an effect of shape perception modification when users stroke the shape with multiple fingers.

Compare And Contrast

Objective: To identify factors that influence Saskatchewan women’s choice between breast conserving therapy (BCT) and mastectomy in early-stage breast cancer (ESBC) and to compare and contrast underlying reasons behind choice of BCT versus mastectomy. Methods: Interpretive description methods guided this practice-based qualitative study. Data were analyzed using thematic analysis and presented in thematic maps. Results: Women who chose mastectomy described 1 of the 3 main themes: worry about cancer recurrence, perceived consequences of BCT treatment, or breast-tumor size perception. In contrast, women chose BCT because of 3 different themes: mastectomy being too radical, surgeon influence, and feminine identity. Conclusions: Although individual reasons for choosing mastectomy versus BCT have been discussed in the literature before, different rationale underlying each choice has not been previously described. These results are novel in identifying interdependent subthemes and secondary reasons for each choice. This is important for increased understanding of factors influencing a complicated decision-making process.

Body Image Disturbances

Despite much recent interest in the objective measurement of body image in anorexia nervosa, many questions remain regarding basic mechanisms responsible for the findings as well as their meaning in the disorder. It is unclear if “whole body” measures assess the same underlying phenomena as the “body part” method, and it is unclear if body image disturbances are etiologic or a byproduct of anorexia nervosa. The possible association between self-esteem and body satisfaction and the relationship of the latter variable to actual size estimation supports the hypothesis that size perception may be closely tied to satisfaction with non-physical aspects of self. Finally it must be determined if over estimation is a function of a general psychological disturbance or of a deficit of specific interest in this disorder. Despite these questions, the way in which anorexic patients see themselves as well as the cognitive and affective responses to this perception remains an interesting and potentially fruitful area of study with this disorder.
