Apparatus (20), including a flexible insertion tube (28) having a distal end for insertion into a body cavity, a first sensor (44) in the distal end configured to acquire a first signal from the cavity during a medical procedure, and a second sensor (54) in the distal end configured to acquire a second signal from the cavity during the procedure. The apparatus also includes a display (50), and a processor (46) configured to present, on the display, first and second measurements corresponding to the first and second signals, and to accept an input selecting one of the presented measurements so as to generate a selected measurement. The apparatus additionally includes a handle (39) coupled to the tube's proximal end, and a haptic feedback device (82) attached to the handle configured to provide, under direction of the processor, a tactile feedback in response to the selected measurement while deemphasizing a presentation of the selected measurement.
