Roadmap Overview
Design Structure Matrix (DSM) Allocation
Roadmap Model
We provide an Object-Process-Diagram (OPD) of the 3ARW roadmap below.
Figures of Merit (FOMs)
- Unit Cost [$]: Unit cost to manufacture the device.
- Clock Speed [GHz]: Speed of the processor (i.e., the number of processor cycles executed per second)
- Ambient Contrast Ratio (ACR) [%]: Ratio of display luminance for on and off state [1].
- L_{on/off} is the display luminance of the on/off state
- T is the display transmittance
- Resolution Density [ppd, pixels-per-degree]: Total number of pixels in a display, which is directly related to the quality of the image (i.e., sharpness)
- Field of View [degrees]: Total angular range of the display or image visible to both eyes
- Display Luminance [nits]: Brightness of the display
- Weight [lbs]: Heaviness of the wearable device and its required parts
- Pixel Response Time [ms]: Time required for a pixel to change. Longer times signify slower transitions resulting in visual artifacts when displaying rapidly changing images.
- Refresh Rate [Hz]: Frequency of display updates per second.
- Memory [GB]: Total storage capacity of device
- Training Time [hrs]: Average number of hours needed to set up and learn to use device
- Longevity:
- Single-use Lifespan [hrs]: Time of use afforded by a single charge of the device
- Total Lifespan [#]: Total number of charges afforded by device
