SmartGlass is not responsive enough to be an adequate substitute for the Wii U’s GamePad, says Ubisoft’s Michel Ancel.

When asked by Shack News whether Microsoft’s mobile device app SmartGlass – which adds second-screen functionality to some Xbox 360 and Xbox One games – would be used in the upcoming Rayman Legends, Ancel responded in the negative.

"It's not as responsive as we need," he said, adding "it's not very popular today".

Even the Wii U’s GamePad presented problems when using a finger rather than its stylus, said Ancel.

"To me, it's not very natural to play with the stylus,” he said.

"I think most of the kids now are more comfortable with tablets, they use their fingers."

"We did some special developments to interpolate what the player is doing."

In related news, Ubisoft has announced that Rayman Legends will feature a bonus 40 updated levels from Rayman Origins, along with a soccer-themed minigame called 'Kung Foot'.

Rayman Legends will be available for Xbox 360, PlayStation 3, Wii U, and PlayStation Vita from August 30.
