Chat based surveys Purpose: To be able to answering surveys using a chat interface. Input: A survey is generated from the WD back-end service (where the survey is stored in a database). Output: Survey responses from the user Software: Which software can make this as easy as possible? Perhaps see the ExperienceSampler, an open-source scaffold for creating smartphone apps for experience sampling ([login to view URL]) The app should include these steps: a. Asking whether it is ok to start a survey with a particular name and provided background information of the survey. b. Asking the questions of the survey, wait for user inputs. Handle different response formats such as word responses or closed-ended rating scales responses. c. Debriefing, or end of survey. d. Allow users to stop and continue at later time. e. Send push notification to remind users to of take or complete a survey 2. Voice based surveys Purpose: To be able to answer surveys using a voice interface. This voice interface should have the same dialog as the chat survey, however, rather than presenting text in a chat, there should a text-to-speech model that speaks the text in the chat, and rather than the user types the text, the user should be able to speak their responses. Text-to-speech should work for Swedish and English from the start. It should also be easy to expand to other common languages. Software: Which voice-to-text and text-to-speech software is as accurate as possible? 3. Behavioral sampling Purpose: To automatically sample behavioral data from the user based on existing sampling software and store the result in a database. Software: Use the AWARE software [login to view URL] Sensors: Here is a list of what should be sampled: [login to view URL] User interface: The user interface should be minimal. The first time the user login to the WD App it should ask for allowing of sampling. Then the user allows this. No other interface is needed at this point. Data storages: The data should be stored using a secure system in a database. One aim of the App is to lower the threshold of taking WD surveys, which should be measured by increased the number of participants that respond, and/or earlier/faster responses.
