### 2022-02-08 : Meeting ###
- multiplatform --> mobile, desktop, touchscreen,...
- both in terms of graphics as well as chipset portability and device size
- reactivity and performance --> from graphics to hardware acceleration
- quantify this by comparing with silicon vendor / hw vendor provided original SDK)
- BOM / performance --> integrated graphics onto SOC
- sub 20 $ hw BOM
- benchmark with target portable graphical libraries such as design systems, or us horonix or alternatives
- UI design tool / IDE needs to generate production ready code
- https://en.wikipedia.org/wiki/Design_system
- for reference --> https://material.io/ (micro animations)
- flutter is a good solution to use as well as JS
