Development and Evaluation of a System for AR Enabling Realistic Display of Gripping Motions Using Leap Motion Controller

AbstractAugmented Reality (AR) in the traditional systems have a problem that the drawn objects are always displayed in the foreground because 3D models by AR are superimposed later than the picture of the actual world. This paper proposed a system to produce a realistic picture of AR in accordance with every depth. We developed a prototype system to verify the effect of the method. The prototype system was developed by focusing on a human hand. This paper utilized a Leap Motion Controller as a motion capture device to acquire the depth data of the hand and fingers

Growth curve of the body weight, body length and tail length in the cotton rat (Sigmodon hispidus)

The body weight (BW), body length (BL) and tail length (TL) of 202 cotton rats, 102 males and 100 females. were measured. Significant sex differences in the BW were observed 3 weeks after birth. The BLs in one-day-old males and females were 8.33 = 0.36 cm and 7.82 +/- 0.69 cm respectively, while the TLs were 2.98 +/- 0.12 cm and 2.88 + 0.28 cm. Growth of the BL and TL was rapid until about 8th week of age, when a steady length was reached. The equations in males were BL (em) = 8.07 + 0.23 x BW (g) - 0.00068 x BW (g)2, TL (em) = 2.79 + 0.11 x BW (g) -0.00037 x BW (g)2 and TL (cm) = — 2.21 + 0.67 x BL (em) — 0.0068 >< BL (cm)2. Correlations among the BW, BL and TL in male and female cotton rats were all highly significant (r 20.98, P < 0.001)
