Topics Navigational Functions Conceptual Screens Hardware Ideas

Button & Rotary Encoder w/ Push Button Simple Compact Encoder makes it easy to navigate menus and adjust values without repetitive button presses. Integrated push button and rotary encoder is convenient. Cons: When entering text you have to move through each digit in order to accept the change and vice versa for canceling a multi-digit change. 2-dimension navigation is probably not recommended. (2-dimensional navagation may add a layer of complexity that is not needed) Integrated Push encoder adds cost.

2 Buttons & Rotary Encoder Pros: Slightly more intuitive initially. Lowest cost option. Cons: Slightly more cumbersome to move your fingers from the encoder to the forward button during navigation in the long run.

Capacitive Touch Slider Slider can be used in place of the up/down buttons. Reduces repetative button presses.

2 Buttons & Scroll Wheel Different feel than the encoder. Similar to the scroll wheel on a mouse.

Joystick Encoder Similar interface to the one used in the automotive industry. Encoder can be shifted left/right/up/down, pressed, and rotated. (7 possible functions) Cons: Too many functions can cause confusion to the user. Up/Down is redundant. Right/Press is redundant.

Topics Navigational Functions Conceptual Screens Hardware Ideas Notes

Notes Speaker beeps for input feedback on button presses alarm when applicable (any button press deactivates audible alarm) Vertical soft-keys could possibly be used on the right side of the screen. Screensaver / Low power mode after configured duration Any button press wakes the screen When slides of this presentation are printed normally the screen should be close to actual size (3.5”) for reference. 1-Dimensional menu system is easier to navigate over the phone and allows for larger font size in general. Login from anywhere feature.
