mobile devices as controllers

[DreadKnight]

Smart-phones and tablets should be usable as controllers.
Android devices could use a Google Play app to scan a QR code associated with a player spot from the pre-match screen in order to sign up for a game, then the device will allow to control the active unit during the players own turn.

• player scans a QR code using the mobile device's camera
• a webpage is opened it's opened and the player is assigned to the according in-game spot
• during the player's turn, he is able to control the currently active unit

Left screen side will contain 6 directional d-pad, showing 7 hexagons, with one circle resting on the middle one, which can be pulled over the other hexagons in order to target the relative spot on the combat screen.
The center should have the skip and delay buttons aligned vertically. Holding both for 5 seconds can allow surrendering (if possible), while doing so, a bar would fill or the screen would turn red. The game screen could also show a notification and progress bar.
The right side of the screen will contain 4 buttons, one being for walking (canceling ability selection) and 3 being for the active abilities. Clicking an ability button would select that ability and start targeting selection mode while clicking the ability button a second time would confirm the ability provided the selected target is valid. If no target is valid and the button is pushed, an error could be display (or a sound played) or the targeting could be canceled.
An alternative design could have an ability cycle button and a confirmation one.
Touching a button should make a little sound in order to enforce tactile feedback.

The page could also allow for easy logging in of the player with his existing account, which could be useful for physical tournaments and bets. To achieve this the page could store a key locally on the phone and send it to the gameplay server.
