Shimizu: What size of glasses would fit the smaller faces of children or women well? To find out, I enlisted the assistance of leading Sony retailers around the world to collect more data. This research led to the development of our smaller 3D glasses (TDG-BR50).
Children's faces are smaller, but the bridge of the nose is also lower, and the nasal bone is still growing. Individual variation in face size and shape is greater among children than adults. However, including a bendable core in the temples, as in the TDG-BR100, would make them heavier. So, for a good fit, we made the TDG-BR50 more flexible overall.
Instead of temples that incorporate a bendable core, we chose plastic temples with a flatter, elongated shape. To make the entire frame more flexible, we eliminated the prominent bridge. Although this affects wearability over eyeglasses a little, the TDG-BR50 fits smaller faces more easily.
For this model, we knew people would want frames in other colors. Simply put, 3D glasses are a way to see enjoyable content. Approaching design from this pure sense of fun, we prepared blue and pink frames in addition to the black ones.
Sato: No matter what your head size may be and whether you're a man, woman, or child, we have you covered with the TDG-BR100 or TDG-BR50. TDG-BR50 glasses easily fit my own children. As for me, my ears are fairly far apart. Statistically, my size of glasses fits one in 500,000 Americans, for example. But despite this, TDG-BR100 glasses fit me easily. Sony TV commercials show parents and children watching 3D TV together, and what made this possible was the development of these 3D glasses.
Sato: Sony 3D glasses excel at producing bright images with a sense of depth, but if they didn't fit so well, the LCD shutters in the lenses would make them feel heavy. At 3D movie theaters, you might see more than a few women and children holding up the theater's 3D glasses with their hand. While watching TV at home, nobody wants to keep holding their glasses, no matter how immersive the action on the screen may be. And even with all the family-oriented 3D videos available, children would still be disappointed if their glasses were too distracting.
I'm very pleased that, thanks to this project, Sony can offer 3D TV for people of all ages to enjoy.
Yuyama: This was our first attempt at designing glasses, and it was challenging. But precisely for this reason, we gained firsthand knowledge we could never learn from data alone, by researching the fit and other details ourselves. As a result, I think our approach is true to Sony ideals in styling and functionality.
For 3D TV to gain popularity, the styling and comfort of glasses is important, not to mention how they look on people. I'm proud to say that success in each respect was only possible because we dared to rely on our own strengths to design the glasses.
