 If you just take a look around you, you will see how almost everything we use and experience in our environment is designed. We live most of us in surroundings that are almost entirely human made. Design involves creating products, systems and services. From my spectacles to your smartphone or computer on which you are watching me, from the room in which you sit, to the mug of tea or glass of water by your side, it has all been conceived and carried out through a process of design. You may ask, is this design or is it technology? Well, design is multi-disciplinary. It engages with all disciplines. So when it comes in contact with technology, it strives to make that technology accessible to people. Its engagement with art leads to aesthetically designed products and clear communication. Its partnership with ergonomics leads to user-friendly products. Ergonomics, that is a word that may not be familiar to everyone out there. What does it mean? Well, a useful definition is that it is the science of designing products to optimize them for varied human dimensions. Ergonomics is sometimes called human factors engineering. We will be discussing this in detail a little later in the module. Let me demonstrate. Take the problem of the jam pickle bottle. See what I do? How easily that got done. The designer of this tool really understood the human hand.
