A feature of lightweight fonts for IoT devices, etc. is that the font file size is reduced based on Universal Design fonts, which have excellent visibility and legibility. The design size was adjusted by widening the size of the character face, the size of the dakuten and the semi-dakuten, and the similar openings such as “c”, “e”, “o”, “3”, “6”, and “8”. , Easy to read character design. Also, Type-S is provided as a "TrueType font" that does not require a font engine to display. A scalable and beautiful display is possible regardless of the drawing area of the device. Therefore, it is possible to unify the character design on multiple devices such as "wearable device" and "smartphone app" that works together with it. On the other hand, since Type-XS is provided in its own font format, a dedicated font engine for displaying is included. It is ideal for embedding in low-spec devices that cannot allocate space for fonts.
