Try Options > User Interface and adjust the User Interface Scale Factor.

It is worth buying a touch / pen / stylus. I have an elderly relative with fat fingers whose life was changed by one of these pens.

I know, but there are some pieces that do not scale, like the chart chooser.

Opencpn is a good software, originally not written for touch. The whole approach is very different from for example Navionics, which is a touch interface software. There is much more functionality in Opencpn, which also complicates the touch interface. There is only so much screen real estate.

As mentioned, I believe it is realistic to have proper touch oriented menus for the upper level of the menus you use when cruising. But first, proper hardware

You might want to look into new color paper white display for high NITS and low power

Re: Contemplating a commercial plotter based on OpenCPN

Any license restrictions w/OpenCPN on a commercial product?

Re: Contemplating a commercial plotter based on OpenCPN

Read the GPL...
The license that governs OpenCPN.



In (very) short: commercial products can use GPLed software while they respect the rules from GPL. In case you modify or develop the software it will stay under GPL.
Producing a chart plotter or navigation system running OpenCPN and selling it is legal.

Re: Contemplating a commercial plotter based on OpenCPN

How about an e-ink based display? It would have downsides but also would have lot going for it, power and clarity under sun being the most obvious ones.

I like my Kindle Whitepaper on a sunny day and I absolutely love the low energy consumption.

It is a proper quality commercial device, with an aim to be also affordable. The specifications below are at this time fairly open:
  • Mounting in bracket or on surface. Only external connection needed is 12V, so easy to install and remove.
  • Casing is water proof, exact final IP-rating TBD.
  • Display full daylight readable, between 8" and 10". Capacitive touch. Anti reflective. 1000 nits or more, exact TBD.
  • Main CPU is standard Raspberry Pi 3 with Wifi and Bluetooth.
  • Latest high performance GNSS with integral antenna built in. No external antenna option.
  • AIS receiver built in.
  • NMEA 0183 bidirectional interface.
  • No NMEA 2000, possibly optional.
  • Supports SignalK and Pypilot.
  • Battery backup to survive power interruptions, and for orderly shutdown.
  • Power consumption TBD, but aim is to make it as frugal as possible.
  • Backlight auto-adjusts to ambient.
  • Low power standby mode with instant wakeup.
  • Hard power switch.
  • Possibly other hard buttons: Man-over-board? Restore standard zoom with current position on center? Full zoom/pan/etc?
  • No depth sounder interface.
  • No radar interface.
  • Charts pre-installed depending on market.
  • Use wireless keypad for downloading charts and other maintenance.
Your views on this, and on the specifications, would be highly appreciated. Would such a product be of interest?

(Sorry, cannot say more about any commercial details at this time.)
