This paper presents valid concerns on current status of elderly population suffering from dementia, why societies should focus more attention in helping them and how this could impact healthcare and social services. This paper also discusses the requirements and methods, which can be used to improve the design process of wearable procam device using Picture based Input Method Using Tapping on Wall Surfaces (PiTaSu) that can help people suffering from dementia. A guideline of proposed requirements is presented that takes into account several different types of problems people suffering from dementia face. An improved user interface (UI) is proposed for people suffering from dementia, as well as the need to implement separate tele-assistance functionality for the informal and formal caretakers.
