Problem statement l.jpg

Problem Statement

  • Alzheimer’s disease and dementia currently affect a large and growing segment of the population.

  • Most people who are initially diagnosed with these conditions cannot be immediately placed in a care facility.

  • They cannot live on their own; a close family member typically stays in close contact in order to take care of them.

  • This situation can become extremely stressful for both the caregiver and the cared-for due to the constant presence required to ensure the safety of the cared-for person.

  • The proposed solution includes an easy to use communication system that will help both the patient and caregiver to communicate with each other.

  • They can communicate via voice, video and text.

Display device software l.jpg

Display Device Software

  • The display device software uses the Skype API

  • The Skype API passes commands in simple text messages between Skype and client applications and devices

  • The Skype API has two main components; the Skype phone API and the Skype access API.

  • The display device software uses the Skype access API.

Skype access api l.jpg

Skype Access API

  • The Skype access API enables external applications to control certain Skype functions,

  • For example to place a call

Characteristics of skype api l.jpg

Characteristics of Skype API

  • All actions performed using the API are mirrored on the Skype client

  • All times and dates in the API are in UTC (Coordinated Universal Time)

  • Multiple applications can use the Skype access API at the same time.

  • Transmission over the API is in UTF-8 encoding.

Initialization l.jpg


  • Use the RegisterWindowMessage method to register

  • To initiate communication, a client application broadcasts the SkypeControlAPIDiscover message

  • Skype responds with a SkypeControlAPIAttach message

Communication between skype and client program l.jpg

Communication between Skype and Client program
