Current Risks to the Project:
Neither Magnetometers nor Hall-Effect Sensors will work:
In the event that we cannot viably sense devices with any of the tested methods, we plan to use IR LEDs and sensors to detect devices as they have a high probability of reliably detecting a new object. We want to avoid this approach as using IR means that we will detect all objects on the table and will require an IR-transparent material to be used as the table top.
Design Changes:
We will no longer be using induction to detect devices due to range limitations. For the approach to work, we would need to tile the entire underside of the table with coils. This would greatly reduce efficiency and increase project costs.
