There are many different forms of care available today for care-dependent persons: alongside mobile care services, care is also provided by family members, neighbours, friends or voluntary services. The goal of the KNOTS project is to develop a server-based mobile documentation and information platform for both professional care providers and service personnel for domestic technology and emergency call systems on the one hand and private caregivers on the other. This communication instrument will allow both professional and informal caregivers to easily store technical instructions or medical and personal information and to subsequently access this information as required. Requirements relating to data protection and their technical implementation are also part of the research work. Commercially available tablet PCs will be used as the operating devices and will allow information to be saved in the form of texts, photos, videos and audio recordings. Speech recognition will be implemented to permit simple and accessible operation. This will allow files to be indexed and located by means of key words
