k 5.4 Summary So Far The thesis SO far in this chapter is that innovations in display technologies have created two new market sectors. Electrophoretic displays have created an e book sector that did not previously exist. Displays with capacitive sensing and touch-screen 'pinch and spread' functionality have reinvented and repurposed the smart phone. The Nokia 9210 featured by us in 2002 was essentially a business tool. Its purpose was to make us more efficient. The iPhone's use of capacitive sensing has transformed a business tool into a mass-market product that changes the way that people behave, interact with each other and manage and exploit information. The addition of proximity sensing, ambient light and temperature sensing, movement and direction sensing both at the micro- and macrolevel enable users to interact with the physical environment around them and if used intelligently can help battery life by turning off functions that cannot or are not being used. Fortuitously, wide-area connectivity is an essential part of the added value proposition of all of these newly emerged or emergent product sectors. The iPhone has also changed the anatomy of the smart phone. Figure 5.7 shows the main components including RF functions. The added value of these components is, however, realised by different entities.
