Wearables: Delivering enhanced user experience through advanced, power-efficient graphics

Wearables: Delivering enhanced user experience through advanced, power-efficient graphics

The user interface is one of the major ways for portable electronics manufacturers to differentiate their products – with well rendered graphical content proving invaluable to the user experience. Now, as we move into the wearables era, effective implementation of graphical interfaces is more important than ever. However, implementing functionality that consumers expect within a wearable device raises all manner of power issues. A key issue for wearables designers is how to deliver high-quality graphics with maximum power efficiency.

The challenge is that the compact form factors of wearables tech limits battery and energy storage options, impacting the operational period that can be supported between charges. Simpler wearable devices such as fitness bands avoid this issue, as they don’t need to give the wearer access to graphical data. Instead this can be done by interfacing with a smartphone or laptop at the end of a training session.

With a device such as a smart watch, however, the graphics – as well as comprehensive touch interface functionality - need to be supported in the product itself. Among the many graphic functions needed in today’s power-constrained wearable devices are rotation, blitting (to render clock timers), fade in/out, simple animation and scaling.

The advent of more energy efficient processor architectures with embedded graphic accelerators and intelligent on-board power management mechanisms can support these requirements. For instance, by taking an approach where only the elements on the screen that have changed are refreshed (rather than having to constantly refresh the whole display), less processing power needs to be allocated and battery life can be prolonged.

To address the graphics and connectivity challenges facing wearables designers, Toshiba has developed its ApP LiteTM series of application processors. These feature built-in drawing and transformation engines that support the migration of smartphone-like user experiences to the wearable sector.
