Indication of the condition of a user
A wearable electronic device such as a wrist watch ( 60 ) is supplied with conventional clock with two pointers ( 32,33 ). The device displays a parameter indicative of how “cool” the wearer has been over the past period as a function of time, using the time axis of one of the pointers ( 32,33 ). “Coolness” can be based on the measurement of related physiological parameters like heart-rate, body temperature, movement, skin resistance or muscle activity. “Coolness” of a person is understood as being the ability to cope with stress. Therefore, the stability of physiological parameters can be used to derive a signal for the subjective trait called “coolness”. All physiological parameters can be measured by sensors ( 10 ) in the watch ( 60 ) or in the strap ( 50 ). The invention is used as a gadget for self expression and emotional feedback.
1. An apparatus for displaying time of a type using at least a rotatable pointer on a dial with a circular time axis, and further being adapted for indicating an emotional condition of a user thereof, the apparatus comprising:
sensing means for sensing at least one physiological parameter of the user; and
display means concurrently displaying (i) time and (ii) a single indicator representative of the emotional condition of the user derived from a stability of the at least one sensed physiological parameter as a function of time, wherein the time and the single indicator use the circular time axis of the rotatable pointer, and
wherein displaying the single indicator includes displaying within an outer circle of the dial a current value and a plurality of past values of the single indicator for a predetermined period of time that is selectable between a first mode that uses a twelve hour time scale of the circular time axis and a second mode that uses a one hour time scale of the circular time axis.
