OUR wind­screen could soon read road signs, guide you through thick fog and show you where to go.

GM this week re­vealed it is work­ing on the nextgen­er­a­tion head-up dis­play which uses the en­tire wind­screen as a trans­par­ent dis­play.

Present head-up dis­play, such as that fea­tured in up­mar­ket BMWs, is lim­ited to small screens di­rectly in front of the driver.

The screen GM has de­vel­oped at its Michi­gan global re­search and de­vel­op­ment cen­tre has a phos­phor coat­ing which re­acts when a small laser projects in­for­ma­tion on it, cre­at­ing dif­fer­ent colours.

GM lab man­ager Thomas Seder ex­plained the safety ben­e­fits in the tech­nol­ogy at the launch.

‘‘Let’s say you’re driv­ing in fog; we could use the ve­hi­cle’s in­frared cam­eras to iden­tify where the edge of the road is and the lasers could paint the edge of the road on to the wind­shield so the driver knows where the edge of the road is,’’ he said.

GM is work­ing with Carnegie Mel­lon Uni­ver­sity and The Uni­ver­sity of South­ern Cal­i­for­nia to de-

Yvelop the sys­tem ahead of its pro­duc­tion de­but in 2016.

Holden ex­ter­nal com­mu­ni­ca­tions di­rec­tor Emily Perry said the headup dis­play de­vel­op­ment is ‘‘a re­ally ex­cit­ing project that has gen­er­ated lots of in­ter­est in Aus­tralia as well’’.

‘‘At Holden we look at all tech­nolo­gies that GM has to of­fer, par­tic­u­larly when it comes to im­prov­ing road safety,’’ she said.

‘‘It is cur­rently an ad­vanced en­gi­neer­ing project so we can’t com­ment on how or where it would be rolled out first, but in time, should the sys­tem be com­mer­cialised, it could be a huge step for­ward in mak­ing driv­ing safer for Aus­tralian mo­torists and pedes­tri­ans.’’

The head-up wind­screen is ex­pect to fea­ture an evo­lu­tion of GM’s road sign recog­ni­tion sys­tem that tells the driver the speed limit.

It would be ex­panded to alert the driver to speed lim­its with a laser draw­ing a ring around the sign.

The sys­tem is also ex­pected to be linked to the sat­nav to alert the driver of their de­sired exit by read­ing traf­fic signs.
