Designing games for entry level Series 40 devices requires more care than for devices with bigger screens and greater power.

Solutions to webinar problems
This section contains problems raised in the webinar exercises, along with recommended solutions.
Minimum size of a standard touch area and its margin
What is the minimum size of a standard touch area and its margin? (The answer should relate to size in cm and amount of pixels in Series 40 full touch devices.)
On Nokia touch phones we recommend:
For Asha full touch phones with a pixel size of approximately 0,163 x 0,163 mm this means:
Compensating for a touch area that is too small
How would you compensate for a touch area that is too small (for example, if the touch area is only 4 mm x 4 mm, with only 0.3 mm margin, what would you do to support people playing with your game?)
You may want to use
Hanlding the red end key
What does your application do if people press the red end key?
- If your game level takes more that a minute or two
- Save the current state
- Allow the gamer to continue the game where she has left the game or close to it, e.g. at a milestone
- You may want to add a pop-up list
- Continue game
- Save status and exit
- Do not save and exit
- If your game takes only seconds
- Close the game immediately
- It is unlikely that the gamer has pressed the red end key by accident, since this is still a single hardware key
- Closing fast means also being able to change tasks fast, e.g. store the phone away and take the subway
- Fast closing might be the reason why people prefer to play your game over a similar game in this situation
Playing sound after loading a game when the phone is muted
The phone is muted, but the user sets ”sound on” during the last game session. How does your game behave when it is opened?
Always choose the option which would result in the least harm - usually this means muting the sound unless it is explicitly requested.
- If the phone is muted, mute the game sound when opening the game
- If the last setting was "mute the game sound", always mute the game sound when opening the game
In our example, it is recommended to mute the game sound when opening the game.
How would you change this UI component?
How would you change this UI component?
This is an improvement because it avoids additional navigation and shows all options "up front":
Best place for in-app purchase access
Where would you place your in-app purchase access?
- Start view
- All menus
- Game level selection
- Views before and after the actual game view
Question: Does Remote Device Access (RDA) support multi-touch gestures for Series 40 phones?
Answer: Multi-touch gestures with Series 40 phones are expected to work in RDA beginning of week 39. Symbian phones are already supported.
Question: Is there an example application which demonstrates the use of an external controller via Bluetooth?
Answer: No, and it is not planned so far.
Question: How many frames per second (FPS) are possible with Asha (full) touch phones
Answer: (Thanks Satyam!)
|Device||Video Recording Frame Rate||Video Playback Frame Rate|
|Asha 305||10 fps||10 fps|
|Asha 311||25 fps||30 fps|
Note that all device specifications are linked from the device names in the table above.
