## Abstract

A remaining-LP-gas display control apparatus includes a consumption obtaining unit that obtains daily gas consumptions in a tank, a consumption predicting unit that predicts future daily gas consumptions for a set number of days such that each future gas consumption is predicted based on the latest gas consumption on the same day of the week included in the gas consumptions obtained by the consumption obtaining unit, a replacement date predicting unit that predicts the amounts of gas remaining in the tank and a date on which the gas remaining in the tank will be used up by using the obtained gas consumptions and the predicted future gas consumptions, and a display control unit that controls a display unit to display an image in which remaining-gas information is superimposed on a location where the tank is placed by using the predicted date and location information.

## Claims

### Claim 1

A remaining-LP-gas display control apparatus comprising:
a consumption obtaining unit that obtains daily gas consumptions in a tank;
a consumption predicting unit that predicts future daily gas consumptions for a set number of days such that each future gas consumption is predicted based on the latest gas consumption on the same day of the week included in the gas consumptions obtained by the consumption obtaining unit;
a remaining-amount predicting unit that predicts the amounts of gas remaining in the tank by using the gas consumptions obtained by the consumption obtaining unit and the future gas consumptions for the set number of days predicted by the consumption predicting unit;
a replacement date predicting unit that predicts, based on prediction by the remaining-amount predicting unit, a date on which the gas remaining in the tank will be used up;
a location obtaining unit that obtains location information indicating a location where the tank is placed; and
a display control unit that controls a display unit to display an image in which remaining-gas information indicating the number of days predicted to elapse before the gas remaining in the tank is used up is superimposed on the location of the tank by using the date, on which the gas remaining in the tank will be used up, predicted by the replacement date predicting unit and the location information obtained by the location obtaining unit.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the remaining-gas information is represented by a color that depends on the number of days predicted to elapse before the gas remaining in the tank is used up.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein the display control unit controls the display unit to display a map image in which the remaining-gas information is superimposed on the location of the tank in a map.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein the display control unit controls the display unit to display an aerial photographic image in which the remaining-gas information is superimposed on the location of the tank in an aerial photograph.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein the display unit is an augmented reality display unit, and the display control unit controls the augmented reality display unit to display an augmented reality image in which the remaining-gas information is superimposed on the location of the tank in a landscape.

### Claim 6 (depends on 1)

The apparatus according to claim 1, wherein the display control unit controls the display unit included in a mobile terminal.

### Claim 7

A remaining-LP-gas display control method comprising:
(a) obtaining daily gas consumptions in a tank;
(b) predicting future daily gas consumptions for a set number of days such that each future gas consumption is predicted based on the latest gas consumption on the same day of the week included in the gas consumptions obtained in step (a);
(c) predicting the amounts of gas remaining in the tank by using the gas consumptions obtained in step (a) and the future gas consumptions for the set number of days predicted in step (b);
(d) predicting, based on prediction in step (c), a date on which the gas remaining in the tank will be used up;
(e) obtaining location information indicating a location where the tank is placed; and
(f) controlling a display unit to display an image in which remaining-gas information indicating the number of days predicted to elapse before the gas remaining in the tank is used up is superimposed on the location of the tank by using the date, on which the gas remaining in the tank will be used up, predicted in step (d) and the location information obtained in step (e).
