“…Therefore, we designed a camera lens magnifier, which physically changes the mobile camera lens by applying a clip on the front camera of the mobile phone. We choose to apply a lanthanide optical glass macro lens [2] with a 3x effect to achieve the magnification without losing image qualities. The clip is made of ABS plastic.…”

“…As we utilized the mobile app's camera as a part of our system, it is natural and convenient for users to interact with a mobile app. We designed 3 workflows for Xiqu performers to help them to visualize their makeup residue (DC2 & DC3) and record their makeup-wearing time (DC6), which are (1) take photos of eyes without makeup, ( 2 We also embedded three vision-based algorithms inside the app, which are (1) eye feature point localization, (2) hsv-uv simulation, and (3) binary threshold, to achieve the visualization effects of our system (shown in Figure 5).…”

“…Therefore, we utilized HSV color space to filter similar colors of black and pink face paints. HSV color filtering contains these steps: (1) enhance the intensity of the blue channel, (2) change from RGB to HSV color space, then set HSV thresholds (lower and upper bound) of black and pink face paints, (3) apply HSV filtering and transfer to single-color images (blue for black face paints, and red for pink face paints). Visualization: Binary Threshold.…”

Chinese traditional opera (Xiqu) performers often experience skin problems due to the long-term use of heavy-metal-laden face paints. To explore the current skincare challenges encountered by Xiqu performers, we conducted an online survey (N=136) and semistructured interviews (N=15) as a formative study. We found that incomplete makeup removal is the leading cause of human-induced skin problems, especially the difficulty in removing eye makeup. Therefore, we proposed EyeVis, a prototype that can visualize the residual eye makeup and record the time make-up was worn by Xiqu performers. We conducted a 7-day deployment study (N=12) to evaluate EyeVis. Results indicate that EyeVis helps to increase Xiqu performers' awareness about removing makeup, as well as boosting their confidence and security in skincare. Overall, this work also provides implications for studying the work of people who wear makeup on a daily basis, and helps to promote and preserve the intangible cultural heritage of practitioners.CCS Concepts: • Human-centered computing → Empirical studies in HCI; Assistive technologies.

“…High refractive index glass bead is mainly made of water quenched glass materials with high refractive index. After drying and grinding, they are fired by flame [4][5][6][7]. Glass is a metastable substance that is prone to spontaneous crystallization under certain thermodynamic conditions, thereby affecting the property of the glass itself.…”

In this study, BaO-ZnO-TiO2 SiO2 was used as the research system, and IR, XRD and DTA analysis were used to study the structure, thermal behavior, crystallization phenomenon and chemical stability of the glass when different proportions of ZnO gradually replaced BaO in this system. The results indicate that replacing BaO with ZnO does not change the amorphous structure of the glass, and the density of the glass increases with the increase of ZnO content. With the increase of ZnO content in glass, the tendency of devitrification increases during cooling, indicating an increased tendency for surface crystallization of glass. The glass with high ZnO content has the highest density and refractive index, and has the best water resistance. However, at this time, the glass is easier to crystallize after heat treatment.

“…Widely used in traffic signs, vehicle license plates, life-saving supplies, emergency warning signs and other fields. [1][2][3] High-refractive-index glass beads are mainly made of high-refractive-index glass water quenching material, which is made by flame spraying after drying and grinding [4][5][6][7] . Therefore, a qualified high-refractive-index glass raw material that is not prone to devitrification is a prerequisite for the preparation of high-refractive-index glass beads.…”

In this paper, BaO-ZnO-TiO2-SiO2 is used as the research system of high refractive index glass, and IR, XRD and DTA are used to study the structure, thermal behavior, crystallization and chemical stability of different glasses when Al2O3 gradually replaces CaO. The results show that when Al2O3 replaces CaO, the glass still has an amorphous structure. With the increase of Al2O3 content, the glass structure first becomes tight, and then due to the formation of [AlO6], the glass network becomes loose, and the glass density peaks with the increase of Al2O3 content. DTA analysis showed that with the increase of Al2O3 content, the devitrification trend of the glass increased during the cooling process, the crystallization peak moved to the low temperature direction, and the exothermic effect weakened, indicating that the surface crystallization trend of the glass increased and the overall crystallization became weaker. The results show that the density, refractive index and water resistance of glass microspheres containing only CaO are the best, but the crystallization of glass is obvious during heat treatment.
