Effective use of sensor methods to assess physical behaviour (e.g., physical activity, sedentary behaviour) requires collaboration between professionals with different expertise and they may not always understand each other.  In this sessions we will distinguish four roles:

(1) method developers who propose new algorithms, devices, or software;

(2) method evaluators who evaluate and compare these methods to advise role 3;

(3) the physical behaviour researchers who use the methods, and finally;

(4) a broad category of professionals involved in making and implementing public health policies based on the insights gained by the researchers in role 3. An individual can act in multiple roles. 
In this session, we will try to facilitate a discussion to find out how we may work better together despite our sometimes very different areas of expertise, with the shared goal of effective using device-based measures.  

We will do this via both audience participation and a panel with extensive experience in the respective roles: Ulf Ekelund, Sarah Kozey Keadle, and Vincent van Hees. Fourth panel member from policy maker role tbc. If you want to volunteer for this, contact: v.t.vanhees@amsterdamumc.nl

Format: After a short introduction, the session will be structured in 8-minute discussion blocks.

Each block starts with a short pitch from one of the panel members to explain a particular challenge they perceive from within their role. For example, a developer may see it as a problem that their method is not always correctly used or interpreted, the evaluator may see it as a problem that their advice is not always followed up, the researcher that uses the method may see it as a problem that feasibility of methods receives too little attention, and those involved in making and implementing public health policies may feel that research output is not always tangible for use in the real world. Next, we will use the multimeter.com app to let the audience propose solutions. The panel members discuss these proposed solutions as they come in.
