A system (1,21) for determining a suitability of an input modality of a first input type for providing a user command for controlling at least one lighting device (31,32), said system (1,21) comprising: at least one receiver (3,23); at least one output interface (4,9,24); and at least one processor (5,25) configured to: - receive, via said at least one receiver (3,23), a signal indicative of said user command for controlling said at least one lighting device (31,32), said user command being provided by a user using said input modality of said first input type, - determine a suitability rating for said used input modality in relation to said user command, - determine one or more further suitability ratings for one or more further input modalities in relation to said user command, - compare said suitability rating with said one or more further suitability ratings, and - output, via said at least one output interface (9,24), information specifying an input modality of a second input type recommended in relation to said user command, said recommended input modality of said second input type being selected from said one or more further input modalities, said further suitability rating of said recommended input modality being higher than said suitability rating. at least one receiver (3,23); at least one output interface (4,9,24); and at least one processor (5,25) configured to: - receive, via said at least one receiver (3,23), a signal indicative of said user command for controlling said at least one lighting device (31,32), said user command being provided by a user using said input modality of said first input type, - determine a suitability rating for said used input modality in relation to said user command, - determine one or more further suitability ratings for one or more further input modalities in relation to said user command, - compare said suitability rating with said one or more further suitability ratings, and - output, via said at least one output interface (9,24), information specifying an input modality of a second input type recommended in relation to said user command, said recommended input modality of said second input type being selected from said one or more further input modalities, said further suitability rating of said recommended input modality being higher than said suitability rating. - receive, via said at least one receiver (3,23), a signal indicative of said user command for controlling said at least one lighting device (31,32), said user command being provided by a user using said input modality of said first input type, - determine a suitability rating for said used input modality in relation to said user command, - determine one or more further suitability ratings for one or more further input modalities in relation to said user command, - compare said suitability rating with said one or more further suitability ratings, and - output, via said at least one output interface (9,24), information specifying an input modality of a second input type recommended in relation to said user command, said recommended input modality of said second input type being selected from said one or more further input modalities, said further suitability rating of said recommended input modality being higher than said suitability rating.
