Các thiết bị di động ngày càng thông minh hơn, mạnh mẽ hơn, và đang trở thành một phần không thể thiếu của cuộc sống con người. Điểm thú vị là chúng cung cấp cho chúng ta một nền tảng để có thể viết những ứng dụng thú vị bổ ích trên đó. Môn học này cung cấp cho sinh viên những kiến thức về nền tảng và cách thức lập trình trên thiết bị di động. Để từ đó sinh viên có thể làm chủ công nghệ và phát triển ứng dụng trên một số nền tảng nhất định (J2ME, Android).
