HCI in IoTBoadu A. Charles Jnr

… is the network of physical objects or "things" embedded

with electronics, software, sensors, and network connectivity, which enables these objects to collect

and exchange data.

Definition of IoT

…the design and use of computer technology, focusing particularly

on the interfaces between people and computers.

HCI by Definition

…any device that accepts input, performs some computations or

processing of the input and produces an output.

Technically, that makes an most devices computers.

Computer by Definition

Touch Devices

Force Sensors

How it works Changes resistance when a force or pressure is applied.

Resistance is inversely proportional to the force applied.

Applications Any project where you have to know how much pressure user applies on a button.

Touch DevicesHow it works Measures component position on the x-axis (right or left) and the y-axis (front/up or back/down).

Applications Controlling speed and/or direction of mobile devices - quadcopter and other robots.
