What is Portble handheld devices?


Portable devices are those intended to be moved regularly, but not necessarily for handheld use. Portable device design has requirements of rugged packaging, being relatively compact and lightweight, and sometimes requires battery operation. Handheld device design must ensure that the device can be comfortably held by a person and has a number of added constraints: very lightweight, intuitive to use, easily read display, button presses and touchscreen use must not be fatiguing, usually battery operated, can’t get too warm to hold, and more.

Portable device design and handheld device design incorporates associated electronic designs into packaged products. Enclosures for these devices must be lightweight and often water-tight sealed, but they should also be able to withstand physical abuse while being ergonomic and easy to use. Tablet design is a subset of handheld device design, where the overall device is very flat and the majority of the device front contains a touchscreen display.

The combination of these factors makes the design of portable and handheld devices a niche area of expertise. To maximize success with minimal cost, short schedules, and low risk, a system engineering approach analyzes use cases and specifications within a proven design processes. Tradeoffs between hardware, software, and packaging implementation have a huge impact on the technical, financial, and production success of the product.
